External hard disk not detected in My Computer and in Disk Management

Question: External hard disk not detected in My Computer and in Disk Management

I have a problem regarding my external Toshiba hard disk 500 GB where it can?t be detected in my computer and also disk management. I have formatted the external HD since I was asked to format it when an error popped up.
So I formatted it and after the formatting completed, I tried to connect the hard disk to my Windows Win 7 laptop. When I connect it to the laptop, it can?t be detected and yet the hard disk is blinking with its white light like it used to when it is connected to the laptop. I tried the disk management thingy, but it can?t detect my hard disk. I tried in other laptops but the result is same
What can I do to make it better? Please help me.

Preferred Solution: External hard disk not detected in My Computer and in Disk Management

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: External hard disk not detected in My Computer and in Disk Management

First off, how old is your Toshiba external HDD? Also, when it starts to spin up, do you hear any sort of clicking or whining noise?

If you hear any noises that sound off, it's possible your external HDD is failing.

When you formatted it, what file system did you use to do so? Because sometimes even if Windows can't detect it, I have had success with booting with a Ubuntu Live CD, and then connecting the external HDD in order to format it that way. It all has to do with how Windows formats HDD's and how Ubuntu and other Linux systems do.

If you can I recommend downloading Ubuntu onto a CD and boot to it on one of your computers, in the Live CD mode, so it doesn't install anything. Once its loaded, plug in the Toshiba and try to format it as NTFS (this is important, because Ubuntu doesn't use it as a native file system, so you need to make sure that NTFS is selected on the format window, not EXT4 or the other types of Linux OS File Systems)

If it doesn't work, post back here, and I will see if I can help you some more. Also feel free to PM me if you have any other issues.

I have had the same Toshiba external hard drive for years and have never had any problems plugging and using from any machine, mac or pc. I recently had to reformat my hard drives and re-install windows 7, and ever since I have been unable to access my external from this machine. It still works fine on my laptop, and when I plug it in to my tower, it still recognizes that "External USB 3.0" has been plugged in and downloads the drivers. However, the drive appears neither under my computer nor disk management, nor diskpart -> list volume. It does show up in my device manager as USB mass storage but uninstalling the drivers and plugging it back in does nothing. Is there anything I can try before moving all my files off and formatting the drive, and will that even help? Thanks for reading.

I have a samsung SV0411N ATA IDE hard disk, just enough to meet my memory needs.the problem is it doesn't get detected, there is no mention of the device in MY Computer. I tried to install XP on it, but set up displayed a message saying it could not read the drive.I used Vista disk management, from another HDD and in disk management, the disk finally showed up. but as soon as i start disk management, it asks me to innitialize the disk, i click OK, it returns data error (CRC). and then in the disk management window the disk shows up as a 37 GB unallocated space.when i try to create a new simple volume, it says "operation cannot be completed because the disk is not innitialized"Chkdsk dosen't read the drives, the samsung doesn't even have a drive name yet.

Hello all. I've used this forums many times before and decided to join. The information is very good here.

Anyway, I'm working on a friends computer (Dell Optiplex GX520 with Windows XP SP3) who had some spyware on it. I think I have it all removed but I have this one strange issue I've not come across before. I discovered it when trying to run the disk defragmenter and I kept getting an error message that said it was unable to start. The C drive is present there and other USB drives that I connect as well. But when I go into disk management, the only thing listed are the USB drives and the CDROM drive, NO C drive or any other volumes. Also, when I tried to run chkdsk on reboot, I get a message saying that it could not check the disk for some reason (flashes by too quickly). Can someone shed some light on possible conditions that would cause Disk Management to not be able to see the main Volume?

BTW. I removed some trogans and installed MS Security Essentials. Computer seems to be working fine except this issue. I don't have much history on the computer. Hard drive is reported in Device assignments as ST3808110AS, I'm currently running sfc /scannow to check Windows files.

System File Check just finished. I need an XP Pro disk to repair Windows and I don't have one. Oh well. Please let me know if there's a way around this.

Answer:No hard drives detected in Disk Management but C drive is in My Computer. ?

Can you post a screenshot from Disk Managment?

Logically...any connected drive should always appear in two places...the BIOS and Disk Management.

The only possible reason that I can think where this might not if two drives are assigned the same letter by Windows, only one can be reflected.

As for C: being reflected in Windows/My Compter...any version booted into appears as the C: drive, as any person who does multiboots will tell you. The C: drive is nothing but a designation for the O/S partition/drive booted into.

As for your XP Pro situation...there is no way around the requirement for the system files for the applicable O/S installed. XP Home is not Pro and vice versa.

please help me .am currently running windows 7 build 7077

Answer:External hard drive not seen in disk management and computer

USB drives dont show in BIOS.

The USB adaptor may be USB 2 and your USB may be usb1 and as such is having trouble seeing the drive.

Or your USB sockets or drivers are faulty, try another USB device in them

One day I pulled my external hard drive straight out of my computer (didn't use "safely remove hardware"). From now on it isnt displayed in my computer, and it doesnt appear in disk management either. When I open device manager and then open my WD SES Device, it tells me the device is working properly.

I've been having this problem for a few months now. I recently built my own computer, having been on a lap top for a couple of years, and found my old external hard drive. I plugged it in to the new computer, and it said something about needing to be formatted, which I promptly did due to nothing of importance being on it. I went to sleep, and woke up to see that it couldn't be formatted.

This is where my issue begins. It no longer appears in Computer, or Disk Management. Disk Management won't even load if I have the drive plugged in. There seems to be no way at all to format the drive, since Computer, and Disk Management both don't load when the drive is plugged in. Any help?

I have an external hard disk which got corrupted. When i connect the disk through USB it shows as an unknown device in the disk management with no option to format.

In My computer the device is showing as H: drive but unable to access it. It asks if i want to format or not but when i go for format it does not do it. I want to erase the disk completely as of now. What should i do??

I tried to load it from linux but there it shows as Device Error. Disk Failure is Imminent.

Can something be done or is it a hardware failure.

Answer:External Hard disk showing as RAW in disk management

Sounds like the drive is failing or the circuitry in the enclosure is faulty.

I would first remove the drive from the enclosure and hook it up as a slave to a desktop PC. See if you can then access it. If you can, then post back for further instructions with the version of your OS.

I have an external hard drive that wasn't showing up anywhere on my computer, so I replaced the hard drive case and now the external hard drive is found in device manager, but not in disk management or my computer. I am running windows 8, and there is data on the external hard drive that I would like to have access to.

The disk drive that is in the case is a Samsung HD103SI

I have used the rescan command in disk management. It showed as Disk 2 Unknown and not initialized. (Please note this is not a new disk and it has data on it that I am hoping to retrieve).

Hey everyone,
I just purchased a new external hard drive for my laptop. I have a Sony vaio, and the hard drive I bought is a Micronet Platinum XL 500gb. I turned it on and it didn't show up in My computer so I went into the disk management and noticed it was not activated. I activated it and then still nothing.

That was obvious because the drive had not been formatted. So I clicked create new partition and started formatting it. All was fine, it was late so I went to bed, got up in the morning to see how it completed and it said that the format was NOT successful. Now it won't show up in My Computer, nor will it show up in Disk Management. Should I just create a WIN98 bootdisk and format it from DOS, or is there something else I can do?


Answer:External hard drive not showing up in Disk Management

If it won't show up, I don't see how you can format it in DOS.

Anyway, check out Device Manager and tell us more.

Other suggestions:

1. Test your drive on another pc
2. Check your bios settings

good luck

My external hard drive seagate 1TB not showing in my computer and disk management. It happen after I install seagate dashboard. It showing in device manager under disk driver but I can't access this drive. I'm trying to get into BIOS while inserting the external drive but my computer stuck. When I pull out this external hard drive my computer can enter bios and boot up normally. Please help. I got very important data in my external hard drive. TQ very much


I assume that if you start without the 1TB HD that everything works normally.

If this is true, when you connect the 1TB HD, do you get any indication that you have added new hardware? You should.

Is your connection to the 1TB HD via USB?

Never mind. One of your images shows that the Seagate is recognized. From that, I conclude that the USB interface is good

I'm currently using a Samsung NP-QX410, and I'm trying to install an external hard drive onto the laptop so that I can backup the data.

The hard drive is a Western Digital Scorpio 750GB
The hard drive enclosure is a Vantec NexStar TX 2.5-Inch SATA (I know it's cheap. That might very well be the problem).

When I plugged in the hard drive into the USB ports (I've tried all of them), the light on the enclosure lights up and I can hear the hard drive spinning. When I look around, I can't find any signs from my laptop that a hard drive has been plugged in (or that anything at all has been plugged in for that matter). After some digging I found out it's suppose to appear in the Disk Management page, then create a partition and do a few other things with it.

My disk Management shows no signs of the hard drive though. All it shows is Disk 0 (the basic disk) and CD-ROM (for DVD's).

To me the problem just looks like I just bought a cheap enclosure, but I'd rather ask to make sure there isn't an obvious step I skipped. If anyone has any ideas I'd really appreciate some help.

I have a Simple Tech Pininfarina 320 GB external hard drive that is no longer recognized by two different PCs, even under disk management. When plugged into the USB, the PCs do try to install the driver, but fails. It is recognized under Devices and Printers as Unspecified and with the information Model-Simple Drive, Category - Unknown, and Status-Software is installing for this drive. The troubleshooter searches for a driver, but does not find one. Basically I get the information that "There is a problem wiht the driver for USB Mass Storage Device. Reinstalling the driver might fix this problem." But I cannot find a driver for this hard drive.

Can anyone steer me in the right direction?

Thanks in advance!

Answer:External hard drive not recognized in Disk Management

The system is telling you that there is a problem with a USB driver, check in the Device Manager for any yellow warnings. Under Universal Serial Bus Controllers you will see a driver for USB Mass Storage Devices, right click and uninstall it then reboot, Windows should reinstall it, or go to the motherboard's manufacturer's site and download and install the latest chipset drivers..

There are two other possibilities, the hard drive has failed or the circuitry in the enclosure has develpoed a fault.

Remove the hard drive from the enclosure and (if you have access to one) hook it up to the internal connections of a dektop PC. Or, purchase a USB Hard Drive Adapter (about ?10) from a computer store or eBay and then plug it into the USB connection on any computer and see if you can then access the drive.

I brought a Seagate Expansion Hard Disk about six months ago and have never had problem with it till now....
The problem is that my HD does not get detected if its plugged in after the windows startup.... In most cases it hangs my PC. The green light blinks so I'm positive that it's not a problem of the HD. The safely remove hardware icon also comes up. But the Autoplay menu doesn't show up and its icon wont be there in My Computer (that is, if I'm able to open My Computer. As I already stated, in most cases, the PC gets stuck).
I discovered that there are no issues if I keep it plugged in the USB port before the startup, but that is an inconvenience since I only have one free port . Ive tested with other pen drives and they work just fine. I even tried plugging it to a different port, but to no avail. It would really nice if you could help me with this....
Thnx in advance.....

Answer:External Hard Disk not being detected...

Try it on another machine. It sounds like the drive is having some problem. Run chkdsk /r on it in the other machine and check for bad sectors.

Hopefully, the data was backed up recently. External drives are the most unreliable of all storage media. If not, you better make a fresh backup in case something is wrong with the drive.

I did not even know of such things a few days ago, but in diagnosing an issue I was having, I discovered that all of our external hard-drives, regardless of which of our computers they may be connected to, show as Active in disk management.
All of our ext. drives are identical 1-TB Transcend; one is brand-new and we have had the others for a couple years.
If I ever did anything to these hard-drives that would make them show as active, I have no idea what it may have been; they have probably been like that for a long time.
The only reason I even found it out was that I had to look in Disk Management.
Has anyone else had their external hard-drive to show as Active ?
Is this just a weird thing with Transcend drives ?

I joined the forum as the activity seemed high and knowledgeable . Here is my problem.

I have an 500 Gb external hard drive (one of those slimeline jobs) and use it for backup and external storage fvrom my personal laptop.
It worked fine for ages and for a while I didn't use it (didn't need it).

When I went back to use it recently it wasn't detected by my laptop (Win 7) anymore. I can feel and hear it spinning but it is not being detected. Being somewhat technical I tried the following

- I went to my local PC hardware store and bought a new cable. They helpfully plugged it in there and it showed up straight away there.
- When I got home I plugged it into laptop and again not detected.
- I trawled around disk management and no luck in it being seen.
- We have a desktop PC in the house (running Vista) and when I plugged it in there it was seen find there as well.
- My other USB devices are not having any problem so as far as I know the ports are fine.

Any ideas as I am tearing the hair out of my head

i had an old notebook with an overheating problem that I thought I had fixed, so I transferred all my music and picture files to it. then the problem recurred and the computer won't reboot. So I pulled the hard drive and put it in an enclosure I've used before, and am working through trying to get it recognized by my new notebook as an external hard drive.

Device Manager recognizes the drive and indicates that it is working properly, and it appears in Disk Management as well. However, in Disk Management, it shows as Disk 2; Unknown; Not Initialized. When I attempt to initialize it, I get the error "The request could not be performed because of an I/O device error."

I've tried to initialize it as MBR and GPT, with no luck, and I've checked the device drivers to make sure they're up to date (they are).

What else can I try? I will try anything, but if it's hopeless, I need to know that too. I just don't want to give up if there's a chance!

Hi all,
I had a problem of Windows 7 x64 Pro not seeing my 8TB Seagate USB HDD no matter what I tried, it just would not show anywhere except in "Devices and printers" and there was nothing I could do with it there!
After several weeks and hours spent on the net searching for an answer I struck the resolution by chance, because i like to fiddle about my operating system.
In case someone is still facing such a problem of external USB HDDs not being recognized and not even showing in "My Computer" or in "Disk Management" (as I had), here is what I did to resolve this problem:
1. Open "Device Manager>Universal Serial Bus Controllers",
2. Look for the USB "Mass Storage Device" and uninstall it by selecting it and hitting the "Uninstall" menu button at the top (with the red X on it),
3. Do a "Scan for hardware changes", the system will find and install the appropriate drivers and you should be able to find and use your device now.
I hope this will be of help to someone.

I've had my Acer Aspire 5310 laptop for a few months now with Windows Vista. I have an 80GB hard drive, partitioned into two drives as default.

Until now I've never noticed that the numbers didn't add up. I know when you buy and 80GB hard drive, it should actually show up as less due to bits and bytes and what not (80GB=74GB roughly) but I found something fishy in Disk Management. There is a drive showing up with no letter assigned to it which is nearly 10GB in size and after doing the math it accounts for the 10GB i lack after adding my two 32GB hard drives together.

So I have 2 x 32GB drives plus this weird drive which is 10.

I have attached the screenshot of disk management.

If anyone knows what is going on here I would very much appreciate it!

Cheers, Darren (newbie)

Answer:Problem with Vista Disk Management/Being robbed of hard disk space!

has this just recently appeared? This is a longshot, but if you have Kaspersky lap installed then that could be the problem. It autologs roughly 10 gigs of data without your permission, it is easy to get rid of, but annoying none the less.
However this doesn't seem to likely as what seems to have happened here is that you have accidently split one of your hard drives into two. Either that or a program like deamon tools has created a virtual drive. Do you use either deamon tools or alcohol 120?

Hello, i am using a seagate 1TB harddisk. When i connect it to usb port in front panel of my CPU, the computer is not detecting it.

But When i connect it to usb port in back panel of my cpu, It works fine. My system detects the hard disk and and everything is fine. How to correct this strange problem

Please help me.each and Every time when i want to connect my hard disk, I have to take my CPU out from its shelf and connect it in the back usb port. Its tideous for me.

Answer:Seagate external hard disk not detected in front panel USB port

Well not exactly knowing what type of a computer we are talking about here, I can only say, that what your are reporting is completely normal. Most computers I've ever touched have passive styled USB ports on the front of the computer, and aggressive USB ports off the back that can handle just about anything you can hook up to it.

So stop trying to connect that external hard drive off the front, not enough power and not enough data exchange rates. I would recommend that if you have all your USB ports off the back of the computer taken, I would start thinking seriously about an "amplified" 4 port USB HUB. Remember the HUB your looking for has it's own power source, and does not relying on the computer at all for it's power.

The following one is a good one, a friend of mine got her's about a month ago and has not yet reported any problems.

Hope this all helps....

hi i am new to this and 18 about to go to uni next week so i need some help and FAST! i bought a 320gb hardrive in june 2010 and it was perfect i made a back up of my whole HP system. However a friend of mine plugged my hardrive into her apple mac and i think my hardrive must have synced to her hardrive called time machine or something like that and now i am trying to use my hardrive in my hp laptop it wont work.

ive tried everything it wont show my computer i searched for help all over the net and with technicians on the phone saying to go into disk management and its not there either. One techinician was sayin i might have to reformat it on the mac.

this cost soo much money and i cant afford to buy another one nor can i afford to lose all my data on this one..

please is there a genius out there that can help me!!!!!!!!!!!

Answer:Hard drive not recogized in my computer or disk management

Timemachine shouldn't automatically synchronise to the hard drive, unless told to do so. Also, in order for time machine to function on that drive, it requires it to be formatted in the MacOSX native filesystem.

In case your not aware, Timemachine is Apple's backup software, designed to backup Apple systems.

If the data on the hard disk is not of any consequence (e.g. it contains no essential data), it can be formatted as NTFS, which will then be read by Windows. Unless it has been formatted as a Mac OSX partition it should be read natively anyway. In other words, it should be NTFS still.

Lets go back to basics:

1. If it's an internal hard drive, does BIOS identify the hard disk?
2. Your positive disk management doesn't identify the hard disk?

You could use a bootable partition editor like GpartED to boot from the DVD drive and inspect all your connected partitions.

You could also boot from a Linux Live distribution like Ubuntu as well, which would enable you to check your connected partitions/drives.

The fact Windows is refusing to identify that hard disk is leading me to suspect its been re-formatted as a Mac OSX filesystem and as such can't be read from Windows. If its been re-formatted your data is already lost, in which case just formatting it will resolve your problem.

my hard drives are working properly but they are not displayed in the disk management.
so what can i do for it?
and my computer icon on the destop was deleted by mistake so from where i can get back my computer icon also i deleted the icon from the recycle bin..

Answer:hard disk not displayed in disk management

Hi chinu89,

As far as the icons go, the following tutorial covers the procedure to restore both the icons you mentioned: Desktop Icons.

Do your drives show up in Windows Explorer?

Please attach a screenshot of Disk Management so we can see what it looks like as things currently exist. It will be easier than asking a dozen questions about what is or isn't there. We can then proceed from there.

Also, please update and run a full AV scan with your security software. Also, download, install, update, and run a full scan with Malwarebytes: This type of problem can be caused by malware - so let's rule that out.

I hope this helps.

Thanks and good luck!

I am having this Hard Disk problem. My old Hard Disk (Samasung 500GB) (bought in 2010) started showing signs of corruption (like Windows doing chkdsk at every boot, and data getting lost). So I bought a NEW Hard Disk (Western Digital 1TB) last month (Sep 2016) to backup all the data from old one. I didn't have time to backup but wanted to use PC so I Clean Installed Windows 7 64bit on the New Western Digital 1TB and used it about a month without any problems.
A couple of days ago i decided to backup up the data. I reformatted the New Western Digital 1TB with Gparted and did a clean Windows 7 Install again. I connected the old Samsung 500GB to the motherboard and started copying the files to the new Western Digital 1TB.
Suddenly Windows showed me an error "Windows detected a hard disk problem" which makes sense because the Samsung 500GB is old and might be failing BUT the error is showing both of my Hard disk in the dialog box.
Is my new hard disk corrupt as well?
Why is Windows showing my new hard disk as failing?
Can Windows mistakenly show both hard disk in error?
Please help i am confused. sorry for a confusing question. i will answer anything required.
I have taken the screenshot of the error message, they are in attached files.
1)The 1st Screenshot shows both my Hard disk in the error box (OLD Samsung and NEW Western Digital WD)
2)The 2nd Screenshot shows only one of my Hard disk and its the new one (Western digital WD)

hello I need some help with a hard drive I just put into my system is this is the wrong part of the forum please let me know

I recently installed Vista with on this machine with this new HD deatched though it had previously been used in this computer running xp.

It is a IDE hard drive and although device manager recognizes it as a disk drive I cannot get windows explorer or disk management to notice it. It has a ntfs format.

Thanks please let me know any additional info I should post. my other drive is SATA drive

Answer:2nd HD (IDE) not detected by disk management

Hi Usurperr, and welcome to Vista Forums.

It sounds like you may not have you BIOS setup properly for the drive. Consult with your motherboard manual for this to help you also. You will need to check in BIOS to make sure that the port you plugged the new IDE hard drive into on the motherboard is set for IDE in the BIOS (CMOS or Integrated Peripherals) settings and not for SATA or RAID.

Also, double check you IDE ribbon cable and power connections to make that they are secure and fully connected.

Hope this helps,

I will enclose here my complaint which I send to motherboard maker Gigabyte, regarding USB external hard disk problem. Please read it and if anybody knows how to solve this, thanks.
My computer has external hard drive connected to USB 2.0 port(s), which is extremely slow. Drive is Transcend StoreJet. No drivers exist for it. It works perfectly for other I/O operations like copy, paste, delete,etc. When I try to make hard disk image with any program, and store it on Transcend Store Jet, speed starts with 50MB/s but drops to nearly zero in few minutes. You can see example on attached picture. It is the same with any program. Disk image would take more than one day to complete, if it completes at all. Actually, I never managed to finish image with any disk imaging software. I tried all usual software for that: Paragon, Aomei, Acronis, EaseusToDo, Drive XML, etc. Are there any USB or other drivers which are responsible for this issue? Can Gigabyte be serious regarding its costumers and provide them solution in order to use USB ports for most important thing (backup)? In this case, making disk image is totally impossible. USB 2.0 ports have speed оf 480 Mbit/s, theoretical. This is far cry from situation here. So, ... Read more

Answer:Problem with slow (impossible) disk image making on USB 2.0 external hard disk

This could be any issue causing your problem , software , usb drive may have errors on it / or ?
Imaging your 150 Gig via Usb will take time { Mine are about 40-50 Gig } Operating System And Programs Only.
I personally partition my main Drive eg: c:\ and d:\ and so only the operating system is on C;\
Then use the D;\ to store your personal files. , this way your c:\ wont keep growing in size as you are storing everything there.
If you cant actually do anything with the computer because of warranties as you stated "just serviced" , ask them why you cant Image Drive.
1/ Try another hard drive to backup to.{ Usb will always be slower } than directly connected to Mobo.
2/ Use Mini Tool Partition Wizard [ Free } to create another partition -
3/ Remove all Temp Files / Restore Points / etc with Ccleaner { Free ] -
    this will reduce C:\ size to minimal size { defrag drive also }.
4/ Use any program to Image C:\ { I use Acronis }. to the D:\ Backup Folder.
5/ Then copy the image to any portable drive or external if need be.
6/ Use the D:\ for your personal files and folders as a backup also.
Sometimes you have to do things yourself - than rely on Service Centres and Costs.
If you run a Business then you claim all your costs incurred.
All this will take time but you will have backups and feel at ease.

If I am saving a backup to internal hard disk vs USB 3.0/2.0 USB external hard disk

Answer:Speed of saving to internal hard disk vs USB 3.0/2.0 external disk?

There's no definitive answer, it would all depend on which internal drives you had (SSD/HDD, SATA 6GB, SATA 3GB) and which external drives you had and their relative transfer speeds. It's all just guesswork without that info.

Couple of hours ago my Windows 7 could not recognize my external USB hard disk (Maxtor Basic). It came up on Disk Management and Device Manager but not on My Computer. However I fixed it (by deleting its line off regedit in HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices, plugging out the ext. HD and plugging back in). Windows automatically installed the drivers and I could access the drive.

But now Windows shows my Maxtor as a fixed disk drive, instead of "devices with removable storage". I still have the option to "Safely remove hardware and eject media" from taskbar, however I rather have Windows treating it as a Removable USB Storage so that the disk can sleep when not in use. I am pretty sure it has something to do with regedit, so any help would be appreciated.

Is using internal hard disk in external enclosure risky in terms of loosing the data?

Is using internal hard disk in external enclosure reliable to use?

kindly let me know as there is a vast difference in the price of these hard disks. The external hard disk is costing more and if i use internal hard disk in external enclosure price is very much reduced.

Running Windows XP service pack 3 on AMD Sempron 3000+ Biostar board.

Formerly, we were running a 500-Gig external USB drive on this system for years without a problem. I don't remember its drive letter ever just disappearing. It may have happened; but, it was so rare I don't remember when it might have. That drive died so we replaced it.

New drive is a Western Digital 1.5-Terabyte in an Eagle brand enclosure. Problem is it keeps disappearing for no obvious reason. Restarting the computer does no good; but, power cycling the enclosure makes it work again 100% of the time on the first power-cycle try. We have tried the drive on both the USB add-in card with it being the only device on that two-port card and on the native main board USB ports and the result is the same.

We need for this thing to stay on-line as there is an automated scheduled backup that needs to run every day and sometimes twice a day.

I gave my external hard disk to friend and that was a big mistake. I plugged it back to my own PC and clicked on Open Folder to View Files.
All my folders in the hard disk were made into shortcuts. I went to Folder Options and unchecked Hide Protected Operating System Files.
Soon enough I found my data in hidden folders and two more hidden folders called 3535 and System Volume Information.
3535 has 2 files named g249.js and i28282.js

If I delete the 3535 folder it comes back within 5 seconds. I can delete all the shortcuts and the autorun file but they come back once i reconnect the externla hard disk.
Worst thing is it infects everything I plug in like my pen drive. I even formatted it but the 3535 folder and the shortcuts were there after formatting.
I did a full scan of my PC and external hard disk using both Security Essentials and mbam but no effect

Hi all,

I'm getting quite desperate about this as my external hard disk has backups of all my photos, artwork, essays and whatnot since 2003!

I bought this external hard disk (Western Digital) late last year, and it's been working great until today. I normally use SyncBack to backup my files with no problems. So today when I plugged it in to make my usual weekly backups, the blue status indicator light was blinking as per normal. I realized that in My Computer the usual disk space indicator Vista shows was missing. When I double-clicked on the drive icon I got the error message "You need to format the disk A: before you can use it". I tried plugging in to all my USB ports to no avail.

Also, I noticed that when I plug it out it makes this sound like a hard disk shutting down (or a computer shutting down). This has never happened before. What do I do?

I got new Desktop recently, Lenovo K450e, and when I went to plug in my external HD, Seagate 500GB, it didn't show up in either My Computer or Disk Management and there are no exclamation points next to the drivers suggesting that I would need a driver update. I plugged it into other ports on my computer with no luck but when I plug it into my laptop it works fine. I have read so many different forums with no luck. My computer is a Windows 8.1 intel core I7 processer.

Thank you

Answer:External Hard drive not recognized in My Computer or Disk Managment but it is on my laptop

Make sure you update and apply all the Windows updates before trying to use this new computer. You can run Windows Update manually for this

I have been trying to find an answer for hours on google and am throwing in the towel.

I have: HP Desktop xt963, Windows xp sp3, 1.2 ghz processor, 512 RAM, 2 internal WD 40gb HD (one ide and one sata), 1 external Hitachi HD (the problem). The external HD is connected to the system via a generic ide/sata cable adapter.

The external HD is first connected to power, the power turned on, the adapter cable plugged into the HD then plugged into a USB 2.0 recepticle on the computer. (The USB 2.0 was an add-on. The existing USB 1.0 was factory installed.)

At that point, a "new hardware" message appears preceded by the usual chiming sound. An icon saying "safely remove hardware" appears. In Device Manager, the HD is recognized and in Properties it says "device is working." However, the HD is not recognized in My Computer or in Device Management.and accordingly is useless to me

In the beginning, it did work off and on for a while, but lately I can't use it at all.

I have tried "uninstalling" in Device Manager and restarting the computer. Upon restart, the device shows up again in Device Manager (installed) but nothing else changes. I tried connecting via the original USB 1 but it didn't make any difference.

I connected the cable and HD to my wife's Dell laptop (Windows xp) via a USB 1.0 port and viola everything worked just fine.

It would seem (a) there's nothing wrong with the HD or cable adapter or power supply, (b) t... Read more

Answer:External HD Doesn't Show in Disk Management

I just discovered something. After you utilize "safely remove hardware" before disconnecting the HD, the next time you connect it it does not power up (the power light is on but you can't feel the disk spinning) until you hook up to the usb port).

Previously, I had not been using "safely remove hardware" at all so I'm guessing the disk was running when conneting to the usb and that's when it didn't work right. But when power is not running when you plug the cable into usb (and it wasn't just a moment ago) then eveything is normal (as it is right now).

At least I'm going to go on that assumption until proven wrong and you can consider this thread solved.

I am experiencing problems as I try to extend dr O:\ 65GB of a portable HD to use all the unallocated space (9.77 GB) on my Disk 2.
Disk 2 also has dr M:\ @ 35GB.

My problem is the error message as seen in attachment #2.

I then made a Simple Volume and tried to extend O:\ but "extend" was grayed out and not offered. I then returned the 9.77 GB to an unallocated state. Everything is backed up so losing any data is not a likely risk.

I do not know what to do in Win and before I try to use cmd prompt I wanted to ask for advice.
I assume if I have to use cmd I will extend and the unallocated space will automatically be used up, correct?

The PC Magazine Vista book I have offers no help. The terminology is confusing me.

Any help is appreciated.
Regards, Mark..

Answer:external hd disk management extend problem

Hi Mark989. Welcome to BleepingComputer.Vista is not as good as Win7 for adjusting partitions so I would be inclined to use something like Partition Wizard which I have used successfully in the past.. As you are not booting from this drive, you can safely ignore the warning.In your case, what I would do is 1. Remove the new Drive N:. 2. Extend the M: drive into the spare space. 3. Shrink the M: drive into right hand side, leaving the unallocated space next to the O: drive, and then 4. Extend your O: drive.Do each of these tasks one at a time and reboot between each task. luck. Let us know how you get on.

My WD Passport 320gb external drive is not recognised. When I plug it in the light comes on and i can hear the disk fine as normal. But it won't show up in either My Computer or Disk Management.

I've tried Re-Scanning is Disk Management, as well as every single USB port on my Toshiba Equiuim L40 laptop.

I can't assign it a drive letter because literally nothing shows up.

I was hoping to format this hard drive to FAT32 so I can backup my PS3 data before I upgrade it's hard drive. Any help much appreciated, and just to make it clear there is absolutely nothing on the drive I want to keep so it doesn't matter what is lost from it!

Many thanks to anyone who can help!!!!!!

Have external SCSI 3TB RAID - need to get it properly configured in Disk Management to actually show up in "My Computer" as connected drive. Running Win2K Pro OS. RAID contains 8 - 500GB drives, and has been initialized. Disk management shows as: Disk 1 Dynamic 2047.99GB Online and Disk 2 Dynamic 1209.22GB Online, but both are Unallocated. (I changed them to Dynamic from Basic - was that right?)I want them set as RAID-5, but am not computer tech and don't know where to go from here and don't want to mess it up. Please advise!

Answer:Set RAID 5 external SCSI in Disk Management

To use RAID 5 on Windows 2000 Pro you will need a separate RAID controller. Do you have this? Windows 2000 Pro does not support software RAID 5. To implement software RAID 5 you would need a server OS.

Yesterday, I started a download and kept the pc on with my Seagate FreeAgent GoFlex External HDD 1TB plugged in. After I woke up I realized that there was a power cut and the computer went off unexpectadly (I had no UPS or any backup system).And, I found that my Ext HDD was not seen in my computer anymore (It was working perfectly until before I went to bed).
In device manager, under 'Disks' it shows 'GoFlex Hard Disk', but in BIOS or Disk Manager there is no sign of this HDD.

I really need the data in the HDD badly. Please help me recover it.
P.S. I read somewhere that keeping the HDD in freezer might help and give a little more time. Is that true? Worth the risk?

Answer:External HDD gets detected in Device Manager but not Disk Manager or seen in 'My Computer'

Power outage probably killed something in the enclosure or its PSU. The drive in the enclosure is probably fine. I would remove the drive from the enclosure and put it in a dock or install it in a desktop computer before considering freezing it. Freezing is usually reserved for click of death drives, and a last ditch effort.

Windows XP sp2 wont boot from hard disk.

After much to do turns out my computer doesnt recognise the hard disk.

I have a seagate 500Gb SATA hard drive, its about a year old, the computer doesnt get hot in the slightest and it shouldnt be dead. I checked the wiring, as far as i can see, its all fine.

only conclusion i come to is that my hard disk is kaput which it shouldnt be. Can anyone give me any other possible solutions to try out before i cry and/or spend money on a new one? theres a lot of data on it i dont want to lose.

If not, ill plug it in to another computer to check, i havent done that yet because it will take me hours - i can only unscrew the hard drive from one side without rearranging the room.


Answer:Hard disk boot failure -> computer won't recognise hard disk

Is your Seagate the 7200.11 series?

We've been seeing a lot of harddrive issues layely that has nothing to do with the drive itself but bad SATA cables aas the cause. Do you have another one you can switch out?

When you say the computer doesn't recognize it we're talking the BIOS here, correct?

Another suggestion is what you have already suggested but I would "slave" it in antother system and see if you can access it that way.

Hi all, I am hoping someone would be able to help me out on this problem. I'm running Windows 7 Ultimate 64 bit.

Windows detects my external HDD but doesn't show up in My Computer. Drive is detected in Disk Management, indicated as "not initialized". When I try to initialize the drive, it gives me the following error,

"The request could not be performed because of an I/O device error"

What I've tried doing:Do a clean instll of windows - Don't work
Uninstall external HDD driver, turned off power, turn it back on again, reinstalled driver - don't work
Tested the same external HDD on another Windows 7 system - No problems, detected and able to access
Tried plugging on different ports - Don't work

After hours of searching through the web and reading forums, I realized that this is quite a commonly faced issue. Thank you.

I bought a brand new U12-43837 Ultra 500GB external hard drive but as soon as I hook it up to the computer, the computer recognizes the drive, installs the driver, makes the hardware insert sound, but the drive does not appear in My Computer, nor does it appear in Disk Management. A few threads on here say to do certain things with the drive in Disk Management i.e. change drive letter, but the drive doesn't even show up in Disk Management so I cannot do that. Where do I go from here?

Hi All,

I've recently ran into an almost identical problem that was described (but not resolved) in this thread.

In my case, the drive worked perfectly with my system and only recently stopped appearing in My Computer. Also, my drive is still visible and accessible on Windows XP but is not visible on my Windows 7.

I'd be grateful for any useful advice how to restore the functionlity of this drive on Windows 7.

Please let me know if you require any additional information to help resolve this issue.

Thank you!

Answer:Unable to initialize external HDD in Disk Management due to I/O error

Hello, tommythecat.
Is the external drive used much? Is it aging? Damaged (from moisture, shock [dropping] or misuse)?
If you can, back-up all the data to another HDD.
Connect the problematic HDD to the troublesome PC.
Open an administrative command prompt > type diskpart > type list disk.
Is the drive listed?

Cheers - Happy Holidays.

I have a WD MyBook 3 TB external HDD. I can see the drive letter in Windows Explorer but the name I had for it is no longer there and the window freezes when trying to access it, disallowing viewing of any files. I was going to take a look at in through Disk Management, but when opening DiskMgmt with the hard drive plugged in the window never opens and reads 'Connecting to Virtual Disk Service'. When the hard drive is unplugged I can use Disk Management just fine.

The drive is able to be viewed in Device Manager. I tried uninstalling the drivers but this did not work.

I am currently running a "chkdsk /r" on the drive. It has been running for about 9 hours now and is 0% complete on verifying files and folders. (see image) Before it started this step I noticed it was back to normal in Windows Explorer, but I did not try to open the drive to view any folders. It also showed up in Disk Management as that was open in the background when I started the command.
I found this very odd, because once this step started it was back to the issues before.
Do you think the chkdsk is working properly? I can hear the disks spinning and the light is flashing like it is being used. I would like to preserve the 2 TB of data in use, but if it's not an option I would just like to be able to use the hard drive again.
Would quitting out of this cause damage?

ok, I currently have two 2tb verbatim usb3 external HDD. one works perfectly and the other has recently started giving me BSOD for some strange reason. I tried to format the drive and that is when it all started. now whenever i power up the drive it crashes the pc straight away. Pc will not boot with drive turned on. The other 2tb drive works just fine. Dead drive? well I sent the drive to verbatim (seagate barracuda) under warrranty to be repaired and recieved it two days ago. I plugged it in, powered up and all was fine. I then went into disk management to format the drive to NTFS and bang....BSOD and drive is completely invisible and as soon as its powered on it crashes the pc. I already have no hair left so any help would be greatly appreciated.

Oh one more thing, before returning the drive to verbatim i tried it on another pc and had the same problem. I have been unable to try this with the new/supposedly fixed drive as yet.

My company's computer needs to be patitioned and reformat. The system is still working well. I mean, nothing wrong with anything (weird huh?). Ok the hard disk just need to be 'split'. I mean, make drive C & D on the hard disk. I know how to do that... easy... Then the HD need to be formatted & reinstall windows XP. Ok, easy too..

But the main problem occured before I do anything (partition & format). I have my own bootable CD that I usually use for partitioning & formatting.

Ok, i insert the CD & restart.
I went to BIOS & changed the boot order (1st boot: CD-ROM, 2nd: HDD-0 & 3rd: Floppy). Then restart again.
Ok the bootable CD is excellently loaded.
I typed fdisk, then came the first problem. it says something like 'no fixed disk'. I exit fdisk.
Then I typed format c:, 2nd problem occured. it says something like, 'invalid drive'.
I forgot the error message because the pc is in my office right now. I'm currently at home 'begging for help' So the error message is not accurate. sorry..

I think, if I run the CD, the hard disk will not be loaded (or should I say, hard disk failure). & If I take off the CD & restart again, change the BIOS (1st boot: HDD-0) then windows will load! Weird right?

It sounds like it might be the bootable CD you've created is not picking up the HDD's/partitions.

My machine O/S is Windows XP SP3 with all current updates.

A few months ago I had a problem with my boot Hard Drive (blue scree and error code indicated lost boot sector). I installed a new hard drive and rebuilt my system .

I have some files that were not backed up on the HD and would like to try to recover some of these files .
The HD is Samsung SP4002H 40GB IDE Drive. I have put the HD in an external Drive enclosure (Sabrent ECS-STU35) and connected it to my PC via USB. When I turn on the drive enclosure:

Device Manger shows a SAMSUNG SP4002H USB Device entry under Disk Drives; and
a USB Mass Storage Device entry is under Universal Serial Bus Controllers.
The HD from the Drive enclosure does not appear in My Computer or in Windows Explorer.
The HD from the Drive enclosure does not appear under Disk Managment.
Under Disk Management I do see 2 Hard drives (Disk 0 is a 500GB and Disk 1 is 120 GB) - the 40GB drive is not present.
I suspect that my original problem with the 40 GB HD was a damaged boot sector and partion table.

I am looking for ideas on how to make the drive visible to to Windows XP and also some thoughts on how to partition table and files.

Thanks for your help

Answer:Hard Drive Not Show in WIN XP Disk Management

how about putting it into slave and then you can use it to recover all files that have not been corrupted by the bad sectors. you can also get your HDD tables by formatting it when it's slave...

although its not clear why you didnt bother replacing the damaged boot file with the install disc, its only one or two files...and if your lazy like me put the install disc in and do a recovery install, it looks like a normal install but it replaces all the original files like bootloader and other things that i cant think of right now...
