Preferred Solution: What is item Unknown(0x0) in xperf disk io?

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.)

hi all,
I have a question about an xperf diskI/O's item.
whats meaning of flushes item of the diskI/O?
Does it mean that write the log file to disk or other issue?

there is its screenshot:

Why only my driver c has the flushes operation? (as the screenshot of red line)
my driver g is running iometer, but it has not flushes.

thank you!

Answer:xperf disk io graph about flushes item

That's disk cache flushes to the drive - iometer tests a drive by measuring I/O to the disk subsystem itself, and bypasses the cache entirely (as that would skew the results entirely). What you must understand is that some I/O that is written to the disk is actually written to the cache first, because writing to cache is generally quicker than actually putting data to disk - especially when a disk is busy. It can then be written to the disk later, when the disk is not as busy, thus keeping OS performance from getting bogged down due to disk transfer speed. This can be controlled by the application writing the data to disk, or the disk controller itself. What you're seeing is normal behavior, on both drives.

I am running XP and am having a problem with a startup item.
When I go into winip.cfg I have an item called ihiqedukicu. Under command the path is rundll32.exe "c:\WINDOWS\ihiqedukicu.dll",Startup
I have no idea what this file does but when I uncheck it and hit Ok it automatically checks itself again.
I searched on this site and then generally on Google but nothing comes up at all.
I feel that my system is running a bit sluggish.
So..I have no idea what this file is but the fact that I cannot find any information about it at all bothers me greatly.
Any suggestions/help?
I am close to just wiping the drive and starting over.

Answer:Unknown startup item

RunDLL32.exe is a legitimate Windows file that executes/loads .dll (Dynamic Link Library) modules which too can be legitimate or sometimes malware related. Generally when a search yields no results of the dll in question, it can be indicative of malware. The fact that it returns after deletion suggests the file is being protected.Please download Malwarebytes' Anti-Malware (v1.50.1) and save it to your desktop.Double-click on the setup file to install, then follow these instructions for doing a Quick Scan in normal mode.

I routinely take a look at my msconfig startup list just to stay aware. Today I found a new item called Imgtask that was not there the last time I looked (a couple of days).

It originates from HKLM/Software/Microsoft/Windows/Current Version/Run.

Googling it yields a lot of nothing, but implies it may be malware. One says it's associated with Wallet Pix (whatever that is)

Any info on it. I'm going to initiate scans with AdAware and Spybot to see what I can find. I'll also run the scan on malwarebytes site.

Answer:My NETWORK shows an unknown Item ?

Hi Simonwar,
We don't think there is any other client connected to the router. If the computer is both wired and wireless, that might show two different IP Addresses. Make sure the wireless security on your router is enabled, so that no one can connect to your router wirelessly. could be a static ip address also. Make sure the ip address on your computer should be assigned by the DHCP.

To isolate this issue you can login to and check that out. Please follow the steps given below:

1. Open an Internet Explorer and type in "" in the address bar without any quotation mark and press Enter.
2. Click on Login, by default the password might be blank and click submit.
3. Click on DHCP Client List on the left hand side of the page.
4. You can view the Client name and the Client's MAC Address and the ip address which is connected to your router.

Note : If that is a wireless client, you will have to enable the wireless security on your router. That will automatically get disconnected as soon as you enable the wireless security on your router.

If the problem persists, please get back to us with the following information:
1. Model and version number of the router?
2. Number of the computers connected to the router (Wired and Wireless)?
3. If the IP Address is assigned manually on one of the computers?

Thank you.

Question: Xperf help

Hello again ladies and gents,

I had a post recently about a performance drop in specifically Black Ops - it can be outlined here:

I've been messing around with this xperf stuff and came across a curious graph - Interrupt CPU Usage. All my cores except one are flat lined - the other is jumping around 40-75%.

Does anyone know how to read this stuff? Is this bad? Does this indicate a bad core? Is it negligible?

Any help would be greatly appreciated

PC Specs:
Windows 7(x64)/Windows XP Pro (x64)
AMD Phenom 1090t 6-core
Asus M4N98TD EVO nForce 980a mobo
2 x 4GB G.Skill Ripjaws DDR3-1600 PC 12800 RAM
2 X eVGA GTX 465 1024MB DDR5 video cards
Western Digital 320GB 7200 RPM sata HDD
850 watt Thermaltake Black Widow PSU

Answer:Xperf help

During the time this graph was made was the computer idle or were you running something intensive like gaming? If the computer was idle this is acceptable as the OS will use only one, mabe two cores at the most to conserve energy. However if you were playing say Black ops then you should definitely have more than one core running and at a much greater percentage than 75%. The easiest way to test your cpu to ensure it is working properly is run any program that will bench mark test you cpu alone. While you are running the cpu have the task manager open to the performance tab. There you should see 6 graphs next to the "CPU usage history" one for each of your cores (this is assuming you are running windows 7). If they are each above 80% then your CPU should be just fine, but if you see one below this number you probably have a faulty CPU. Hope this helps.

I've been trolling the forums here for a while. Lots of great info but now I actually have an issue where I need some assistance.

When I was booting one day last week I got a nasty BSOD when Windows was trying to load. Then on the next reboot Windows 7 said it couldn't load and needed to do the recovery OS option from the Windows 7 repair on the CD. Well, before trying that I did a cold reboot and it got back into the OS fine so I didn't think much of it. Now, I noticed Ghost shows the C: drive status as "Unavailable" and it can't back it up anymore. It does give me an option to restore from one of my old backups. I'm thinking the MBR got hosed up somehow or something like that. But I'm skeptical to run an MBR repair since I have that 100MB partition on my SSD where my OS resides.

When I first set it up I installed it on my SSD (Intel 510 120GB) drive. One of the qualms I had with the install is Windows created a separate boot sector on the disk drive where it stored my boot files. This is known the the "system reserved" operating system files 100MB partition. Apparently the way to avoid this is to use a third party partition tool before doing the windows install. That way it will keep the Boot sector files on the same partition which is how I would of liked it for doing resto... Read more

I'm running Vista Ultimate 64 on a 500 Gig hard drive with 3 partitions.The problem is I marked one of the partitions,not Drive C, as "active" by mistake.I done a Command Prompt to make it "inactive", but when I started the system up again it wouldn't boot.I used the Vista disk for the recovery process, but I got a message "Operating system unknown on (unknown) local disk" i tried fixing the problem with a command prompt "bootrec/fix boot" ,but nothing happened.When I look at the info in Command Prompt it doesn't show the disk partitions, just Disk 0.Also I can't repair because no Disks are listed to be repaired. If I look at the drive in "My Computer" it is full with a file system marked as "Raw" and it wants me to format the drive.I used "Recover My Files" software and it shows some of the documents that are on the drive, but doesn't show any recovery.I looked at some internet post about the message I got and partition and boot problems like I have, but at this point I don't to try any else to make it worse.I would do a reinstall ,but on one of the drives I have some stuff that wasn't backed up.I never thought about backing it up because it wasn't on the C drive.Any help to solve this problem would be appreciated. ..........Kumpie

Hi, I'm 'playing' around with Xperf and the command line because we have (sporadic but too often) performance issues on a location, especially with a program which use large data files (e.g. 9 GB) from a network share.
The users have Windows 7 machines with >48 core CPUs, 64 GB Ram, SSDs and sometimes the computers are (reported) completely stuck while working but the task manager do not show any suspicious activity. So the hardware should not be the bottleneck.
Because the responsible persons, who administrate the network, stated "it's all ok with our environment" - every time they do this - then I tried to catch the reason with Xperf.

Hi all

I find the standard Hard disc Icons confusing -- with the padlock this would impy to me (or maybe I haven't understood properly) that these discs are SECURE and have limited or restricted access.

I can share these with no problem on a network ( it's what I want anyway).

On Network shared devices there used to be different icons denoting a share ( I think the disk had a pair of hands or something on it to denote a share).

A Padlocked item to me denotes a secured item (or have I mis-understood what a padlock is).

In this case there are only 2 drives but on other systems I might have 8 or 9 drives connected and I'd certainly like to know quickly what are "Networked" drives and what are "Local" drives.

Maybe I'm just being fussy but the Icon does seem a bit illogical.
There must be a better Icon for "Fixed Drive" .

Hi,Bought a G510 running w8.1 in May.  After 3 months of untroubled use I started getting all of the above error messages and problems. Restored to factory image. updated bios and updated drivers problems still persisted, all hardware tests were fine. Contacted Lenovo, laptop needed to be shipped to Germany, from UK as it appears there are no facilities in the UK??, to be examined.  The solution... Lenovo replaced the hard disk. Laptop was working fine again until a couple of weeks ago (about 3 months elapsed since original repair!!)  and exactly the same problems have returned.  The joke is I dont even use the laptop seriously as I dont trust it, and it spends 99.9% of its life as an expensive web browser machine. Surely the drive hasn't failed again, are they really that bad, or does the real problem lie somewhere else? Either way I'm totally unimpressed, no doubt having to send the laptop off for another 10 day holiday in Europe. :-( Anybody got any suggestions whats happening here?  Many thanks

I'm having a problem manually backing up a folder that contains many smaller folders, files, documents, photos etc to an external hard drive.  Things got convoluted and complicated when during the initial copying attempt,  my computer accidently shut down.  From that point on, the situation snowballed after I trashed the first copy folder attempt.  Long story short,  I've made numerous copies, attempted to drag them manually to the external hard drive (E), wasn't able to do it, renamed them and then dragged them back to the desktop and now I have a problem I can't resolve.
For the sake of simplicity, I have 2 folders named "BackUp files". One is on my C drive and the other is on my E drive (external hard drive).  They're  both the exact same size and have the exact number of folders and files on them.
I'm attempting to copy the one on my desktop to the external hard drive as insurance because even though they both open, I don't know which one may be tainted.  (I really don't want to lose this information.)  For example, I can't drag the folder on my desktop to the E (external) drive because I get the following message:  "COULD NO FIND THIS ITEM.  THIS IS NO LONGER LOCATED IN THE COMPUTER.  VERIFY THE ITEM LOCATION AND TRY AGAIN.
How can I resolve this problem?

Answer:Could not find this item. This is no longer located in computer. Verify the item

It may be that the folder moved. Right-click on the Desktop > Refresh and if the BackUp Files folder is missing on the Desktop, it means it was moved to the E drive. You can also use command prompt to verify.
Run the command below:

cd "%UserProfile%\Desktop\BackUp files"

If the command says that the "system can not find the file or directory/folder specified", then it is not on the Desktop

I turned on my computer the other day and it decided to run a checkdisk. No problems, everything was fine. HOWEVER, the next time I rebooted, it said that there was a computer software problem and the exact error was "load dlls for kernel", please contact your support person for assistance. Now, every time I boot up, I get this error. It doesn't matter how I boot up, (safe mode, last known good config, normal) I get this error. I saw on the web that the fix action was to run the XP install CD and do a repair, so I tried that; BUT...when I run the CD, it says, "unknown disk" where it normally lists my partitions and it won't let me continue past there. If anyone can please help me, it would be HUGELY appreciated as all of my children's photos since birth are on this hard drive!!! PLEASE HELP!!!

Answer:Please Help - Hard Disk Unknown

For starters, I'd suggest booting (typically you hold down the Delete key during power up) into your CMOS BIOS and make sure the BIOS sees your drives. Could be somehow the BIOS got corrupted and needs to be re-config'd.

My scope is to save the content in the disk and move it to my PC, is it a mission impossible? Any suggestion is very welcome. Thanks Alex

Answer:Disk 1 Unknown, Not Initialized

I'm not sure you will have much luck if the disk is not readable. You can usually use a Linux distro to try to read it, but you've tried that. If it can be read you can also try Copy & Paste - in Windows Recovery Console. Other than that you could try Recuva and see if that will work. But, if the disk can't be read, I'm afraid there is nothing you can do if those 3 options don't help.

Answer:Disk unknown - not initialized

My laptop took a fall and after that it doesnt enter the boot sequence for windows, stops at the laptop manufacturer logo.

That is bad news mate. Usually a mechanical HDD won't survive physical shock like dropping etc. This is because of the microscopical gap between the head and platter. Heads flying height on modern HDDs is about 5-10 nano-meters. For example: an average human's hair is about 25000 nano-meters in diameter. A drop will most likely cause the head to stuck on platter or cause scratches on platter surface.
I would suggest diagnosing the HDD using "Seagate Seatool" and verifying it's health.

SeaTools for Windows | Seagate
Run the tool and select your external HDD for testing. Then choose "Basic Tests --> Shot Generic" and wait for it to finish.

If the test is a pass, run "Basic Tests --> Long Generic". If either of the test fails, the case will be beyond DIY and you should consult a data recovery pro for recovery.

Hi, i'm new on this forum. I was searching for an answer to this issue in a lot of threads but i didn't find something to fix it.

I built an external hd using the hard disk of my old laptop (Fujitsu MHV2120AH PL) and a Woxter i-Case 240.

When i connected it via USB i went to the Disk Manager and saw the unit as "Disk 1 Unknown Not Initialized". But there was something else, the disk has a size of 120GB but the Disk Manager shows only 700MB.

The Disk Manager didn't allowed me to format this partition and when I press on "Initialize disk" it didn't do anything.

I used a Linux Live CD and I had the same issue, i tried to create a new partition table but it didn't create it and GParted didn't allow me to create a new partition answering that i need a partition table first.

I tried with Diskpart without any result too.

This HD had an Windows XP installed on the old laptop and before dissamble it i made a quick format with the Bootable CD of my laptop. The quick format was interrupted when the program was copying the files necesary to install Windows XP.

Do you have any idea?

Answer:Unknown - Not Initialized Disk (External HD)

Hello Matterito!

You could try a couple of things: changing the enclosure, as this one's controller may be corrupt, or hooking up the disk directly to the computer.
Also, see if your USB drivers need updating.

Following this, it may be that your disk is just damaged. It could be just that the partition table is corrupted, so may be writing full zeros to the disk and repartitioning and reformatting it would help fix the issue. That is in the case that you don't need the information on the drive.

For a while my computer has refused to start Windows. It would get to the screen with the Windows logo and then no further.

I have not replaced any of the hardware since I bought it, and as far as I am aware this problem came on the back of nothing. (It didn't follow any installation of software or hardware.)

Since there is nothing of too much importance on it I decided to reinstall Windows, but after the setup had started it reached the screen from which I was to choose which drive to install Windows to and each was listed as "Unknown Disk." Pressing any button resulted in a blue screen.

If I even attempt to load without using the disk I just get a black screen prompting me to enter the setup disk.

I am currently at work and so cannot post the precise specifications of my computer, though I will as soon as I get home.

In the meantime I gather that I need to look in BIOS to see if my hard drive is being recognised?

I have Googled this problem but each response was slightly over my head, since I'm not sure what type of harddrive I have (though I will once I get home, I have all the documentation).

Though I do not consider myself too dense when it comes to computers, I am not confident enough to fiddle about in BIOS without instructions.

Does this happen when you try and select a partition to install to? I am assuming yes.

The drive you have appears to be a SATA drive. As setup loads you should see at the bottom a prompt to press a key if you need to load 3rd party SATA or RAID drivers. You will need to follow that prompt to load the drivers for your SATA hard drive. That should work.

This 2.5" SATA drive is from a Toshiba that seems to have died this morning. There's no boot, no BIOS, nada.
I removed the drive and attached it via USB to my Win7 box where it shows as "Unknown, Not initialized, and offline." There are no rt-click options in disk management. I can hear the drive spinning, but it shuts down on its own occasionally, and sometimes won't power up at all without a bit of fiddiling.

I've been recovering data from three older internal hard drives for a friend, by way of an external HDD enclosure connected via USB to my laptop. It went well for the first two HDDs but the third, well ....

It's a Maxtor DiamondMax 10 HDD, 120 GB and is also marked SATA150.

(1) On most occasions, the HDD in question does not appear under My Computer. Under Devices and Printers, I see the external HDD enclosure as "USB to ATA/ATAPI bridge" (but not the HDD). In Disk Management, I see my internal drives and CD/DVD ROM but for the HDD in question, only "Disk 2, Unknown, Not Initialised" - I get the option to initialise it as MBR or GPT (I cancel at that point).

(2) On rare and seemingly random occasions, my laptop does pick up the HDD as drive F: but usually asks me if I want to format it (nope!). At this point it also appears under Devices and Printers, My Computer and in Disk Management as 'RAW' and 'healthy'.

(3) On three occasions, I have seen the drive name; on two occasions, all of the files - and on one occasion, I was able to copy four files across to my laptop (before losing visibility of it). So I know all the files are there.

However the HDD disconnects itself (or is disconnected) quite quickly, such that I am back to position (1) for the vast majority of the time.

Recnetly I noticed I had a 4th hard disk drive instead of 3.
The strange thing is that I can't remember adding one..
I just got my 2 internal hard disk drives and 1 external hard disk. But now it shows 4.
Also, when I try to open this 4th hard disk it gives an acces denied error message.
When i look at it's properties it shows this:

Also, I'm unaible to scan the hard disk. For my other hard disks, when I right click, I got the option to scan for virus. This option isn't in the list when I right click this new station.
Here are the menu list by right clicking on the HDD's.

Where does this hard disk come from?
Is it a virus because of a virus?
Why can't I access it?
Is it because of a program I installed?
Do I have to remove it and how?
Please help.

Answer:Unknown new hard disk drive.

Do you have a media player plugged in by any chance? (iPod, Zen, Zune).

That would also show up as a removable drive, BUT, if it was a media player, you would be able to access it.
Mine has done that with my camera also. it would show 2 separate that I can't do anything with, and the other which is where the pictures are stored. If I remember, they are called "removable drive" and "fixed drive.

I guess my first guess would be an external media player. If you have one plugged in, I'd unplug it from the computer and see if that other drive disappears.

Okay so this is my problem:

I have been having this problem for a couple of days now. I have a Western Digital Caviar 120GB IDE Drive connected to my computer, and Windows XP doesn't seem to recognize it, all 4 of the hard drives on the Windows XP install says "Unknown Disk - There is no disk in this drive" If I press enter, it gives me the BSOD. If I press D, it gives me the BSOD. If I press any key it gives me the freaking BSOD. So I checked my BIOS and it only recognizes my DVD-RW Drive and my CD Drive. I started getting confused. I didn't know what the problem was. I believe this is how much in depth I can go through with this, I really need some help fixing this.

Answer:Windows XP Install - Unknown Disk

Ok, what IDE channel do you have the 120 GB HDD plugged into, i.e. Primary Master/Slave or Secondary Master/Slave. Where is the DVD-RW and CD drive plugged into? Is the HDD and the Optical drives on separate cables or on the same IDE cable? How do you have the Jumper pins set? The way it should be setup is your HDD should have the jumper pin set to Master or CS (Cable Select), most new drives come set as CS by default, depending if you have one of the Optical Drives on the same cable. The HDD should be on the end of the IDE cable, any other drives should be sharing the Middle or not at all. The Primary slot/cable should be the one you are using for the HDD. If there is an optical drive on the same cable, it's jumper pin should either be Slave or CS. The Red stripe on the edge of the IDE cable should be pointing towards the Power Plug of the HDD Drive. And the other end should be facing the same direction as all the other IDE cables on the motherboard signifying Pin 1. Make sure the IDE cable is plugged in tight to the drive and to the Motherboard, and that the power plug is plugged in tight. Once you have the jumper pin set correctly, make sure the drive is showing up in the Bios. If it still fails, then if there is a drive sharing the same cable, remove it for the time being.

Sorry for a long post, but the problems have been mounting and I want to be clear with what's wrong...

A while ago my computer stopped functioning. I came home to find the screen black, so I hit the hard restart button, and it got to the screen with the Windows logo and a scrolling blue bar underneath, but when that ended and it should have flashed to the login screen, it just went black. I tried hard restarting several times, and each time it would either go black or, in some cases, restart of its own accord. Sometimes it would flash a BSOD, but only once did it stay up long enough for me to write down any of the information. Turns out it was a graphics card issue (I have an ATI Radeon X800 Pro AGP card) - something about ati2dvag.dll being caught in an infinite loop. I researched the problem, and there seemed to be a way to fix it as long as I could log on to Windows somehow, which I could not do. Even trying Safe Mode only got me a little bit farther - I could get past the login screen and the desktop would start to load before it would abruptly crash and restart on its own.

Finally I decided the best thing to do would be to reformat. After using a hard drive cradle to pull off the data I needed to keep onto my laptop, I figured it would be a cinch to reformat and reinstall Windows. Thinking it would be easy, I decided to upgrade to a better drive so I purchased a 500 GB SATA Western Digital drive online (the old drive is a 200 GB SATA Maxtor) and tried to install Wi...

Answer:[SOLVED] Reinstalling XP - Unknown Disk

Thank you for the detailed post, i wish everybody would give such effort when posting. Now, first thing you should is go back into the bios with both of your hard drives plugged in and check and make sure that your bios is picking up them correctly. It will be show the name of the hard drive and some long number. Then go through the other settings like boot order and make sure that the hard drive is in the list. As for that video card did you update the driver for it recently before the crash, it might of done it automatically. That could of caused the problem. FYI i would of tried Last Known Good Configuration before a reinstall, if it was a bad driver that would of rolled it back to a point before it was installed. Anyways, try those things first and we'll move from there. Good Luck

Brand new external HDD, Western Digital My Book 1230 4TB, 1 week old now. When transferring files from the HDD as well as when renaming or deleting them, I get the error message:

"Item not Found; Could not find this item; This is no longer located in F:\music\[file name]. Verify the item's location and try again.",

while when transferring files to the HDD from any other location other than the drive, I get a similar:

"Item not Found; Could not find this item; This is no longer located in F:\. Verify the item's location and try again.".

The files on the drive are audio files and they cannot be played, as I get an error message: "File reading failed: could not open file "[directory]"; Your input can't be opened: [directory]"
Uninstalling the HDD's drivers through device manager, restarting the computer and then letting them reinstall seems to temporarily fix the problem, which is how I got some files onto the drive in the first place, but it always seems to come back after another reboot or occasionally during use.

I have tried using other external HDDs and they function perfectly well on my PC, and I have tested the WD My Book drive on a different PC and it doesn't seem to run into any errors over longer periods of use, even after multiple restarts of the secondary PC.

I'm pretty sure I have some sort of infection, although I am not sure. My disk is constantly active, grinding constantly every second even when the computer is idle, no matter how much I restart or how long I leave it on. This has been constant for almost two weeks now and it is driving me insane. I did some research, tried to turn off indexing in case it was that, but that did not change anything. I did some disk defragmentations as well, but that didn't help. I have Avast, Malwarebytes, ThreatFire and Online Armor installed, but none of those have detected anything. From what I can tell by looking at the task manager, there is a process called System that identifies itself as NT & Kernel system that seems to gobble up 20% of my cpu in concert with the disk activity I am doing. When I try to locate that particular process though, it takes me to my desktop on explorer with My Computer highlighted. I need help before I throw my laptop out of the window because that noise is driving me nuts. Here's the DDS log, and I've attached the other two logs required as well. Also, when I ran GMER the first time my computer got a blue screen, the second time GMER crashed unexpectedly, and finally the third time worked, but the log file is too big for me to be able to attach it...

The computer[nt4.0 server with service pack 6a] was running fine with two physical hardisk both running on ntfs. Later when I installed the the modem i just couldnot install it. The modem was not detected and the system just stoped booting also. I installed a fresh nt 4.0 on the same primary hardisk formating it as fat. Instalation is sucessful. But the operating system cannot access the secondary hardisk which is ntfs. The disk manager shows the disk but says "partition unknow" although it is ntfs. When i open the file manager and try to access the secondary hard drive it says "drive is not readable. disk structure is curupt and unreadable".When I right click on the drive and i hit properties i do not see the sercurity tab. Since I have reinstalled the operating system the service pack right now is service pack 1.
I want to recover data from the secondary hardisk which I can not access please help.

Answer:ntfs partition is unknown by disk manager

Did you overwrite your original install? If not, you may be able to repair it. I would try to convert the current partition to NTFS, but that may not help. Partitions created by disk administrator can be difficult for another OS (other than the one that created it) to work with. You may be able to save the data using ghost to take a picture of the second partition, then wipe it out and re-create it and use ghost to replace the original data. That may work. Hope it helps.

I have this 160GB hard drive that I have not been using for a while, yet I am very sure it was working fine the last time I used it.

Today when I plugged it in to my new notebook that is running Windows 8.1 now, it doesn't detect my hard drive. I also tried on other notebook and it has the same issue. So I know the problem is most likely on the hard drive.

Using Command Prompt, it says Disk 1's status is "Online", but size is "0".

Here is the status at Computer Management:
Disk 1
Not Initialized

I also tried to Initialize on MBR, but it returned me with "Incorrect function." message.

I tried "Troubleshoot" and the result says:
"USB Mass Storage Device is an older USB device and might not work with USB 3.0
Plug the device into an available USB 2.0 port..."
My notebook has 3 USB ports where according to the manual, 2 of them are backward compatible to 2.0... I tested on each, but it is still not working.

What should I do? Although I have not been using it for a while, I wish to check the content first before formatting it. I might have some forgotten, yet important files within.

Thanks in advance. Hope I can be assisted here.

I am trying to recover data from laptop internal HDD use as an external hard drive to recover data from that HDD. I can't see my HDD in my computer but in DISK Managemnet, there is a message, "Disk 1 Unknown Not Initizalized"

Please Help!!


Answer:Recover Data from Disk that is unknown and not initialized

If the data is critical, and it sounds like it is.. the first thing I would do is use a software that makes a sector by sector backup or image of that uninitialized drive. That way if trying to make it readable by initializing it should hose it, you have a copy.

After that, if you know that the unititialized drive was at one time formatted NTFS then you might try initializing it with Partition Wizard freeware

But it may be worthwhile to talk to someone well versed in disk recovery. There may even be some dedicated forums around for that specialty.

If you get lucky and the Partition Wizard initialization shortcut works, then the files should be there after doing a non-destructive format as NTFS file system.

Assuming that's what it was to begin with.

I have used the tittle from another thread as my issue is very similar, only none of what is posted there worked for me.

So I have a WD 500gb HDD. (Actually I am not 100% sure it is a HDD and not a SDD)
I have plugged it in various PC and laptops. When doing so, you get the usual sound que. It also installs the driver according to the little pop up window.
However after that, the drive is not visible in "My Computer".

When I check the drive in Computer Management>Disk Management, it wants me to initialise the disk. Which, I know I do not want to do (thanks to one of your earlier posts) as this will over write my data.
In Disk Management the disk is "Unknown" and "Not Initialised" It also does not give any volume. Pics of both of these attached.

I have tried using Partition Wisord free. It does not even see the drive.
I have tried using Photorec. It does not see the drive.
I have used R-Studio. It does see the disk, but I am not able to scan it. Again also no disk volume. Again Picture attached.

I am hopeful for a solution, as I feel like the symptoms suggest that I do not have a head misalignment. But I might be wrong on that.

Hoping for someone with some mad skills to help me out here.

I am using windows 8 and I have read previous threads with similar issues that I face but my problem is unique. My 60GB external Hard disk was manufactured by FUJITSU and was taken out of a dell laptop. When I bought a case for it yesterday it was tested in a laptop computer to see if it was working before I paid for the case and it was working properly. However, the owner of the laptop removed the cable without safely ejecting the drive first. Later, I connected it to several computer and it would install and be detected in Device manager, Disk Management and even devices and printers but it does not show in My Computer nor does autoplay options pop up. In disk management it is shown as Disk 1 unknown not initialized as shown in the attached screenshot.

I notice that whenever i open disk management, it prompts me to initialize the disk but when i chose gpt and click ok, this window pops up

We have a laptop that will not startup - 2 lights appear when trying but nothing happens. We need to get data back off it.

I removed harddrive from laptop and connected drive to PC USB with USB to Sata Drive Cable setup. It will not register in Windows Explorer. However, when I go to Disk Management, it seems to see something. It says there is a "Disk 3 Unknown of 465.76 GB" and "Not Initalized". In detail for that drive it says "465.76 GB Unallocated". It also displays a message when I fist enter Disk Management that says "You must Initialize a disk before Logical Disk Manager can access it". It offers initialization in either MBR or GPT partition style. The harddrive is stamped as a HGST of 500 GB capacity.

Listening closely it seems to be spinning. When it started up I did hear some other sounds but not a lot and it was very soft in all sounds - I had to listen very carefully to hear anything. And have not really listed to a drive before to see what sounds it should make. Also, I have not opened it.

I am running Windows 7 on the PC and the laptop was running Windows 8.

I have not initialized it as I assume it will wipe/re-format disk when I am trying to retrieve the data on it. Is it just the case of a drive letter conflict or is the drive just had it?

For any serious troubleshooting, diagnostics or recovery attempt, you should always connect an HDD to a direct SATA port. Usually you can easily remove the header of any Seagate Golex drive and then connect it to an internal SATA port.

Let us know what "Disk Management" reports when you connect the drive directly.

I have a Lenovo Thinkpad X-Series running Windows Vista and I've been losing disk space for the past few weeks. I checked the disk with WinDirStat and it says that there's 40.3 GB of unknown disk space and I'm only using about 20 GB or so on everything else. I only have 3.2 GB left...I've tried turning off System Restore/Shadow Storage and clearing the disk space, including deleting old restore points. I've also tried limiting how much the restore points can use to 1 GB. None of it has worked...I don't really have any large programs and I removed all of my games. I've cleared $RECYCLE.BIN and scanned my computer with viruses with Norton and Spybot S&D. No problems turned up. I've also used the vssadmin list shadow storage and that was only using about 2 GB. Can anyone suggest something? Thank you in advance!

Answer:[SOLVED] 40 GB of missing unknown disk space!

I would recommend going to disk management. I bet the is 40GB of unallocated space. If so you can right click the C: (windows partition) and select "extend" and just click next and it will add the unallocated space to your C: drive.

To get there:

start->right click "Computer" -> select "Manage" -> click on Disk Management in left column.

Please let me know if this works for you.

My C: partition is 100GB large, I have already uninstalled every redundant program, leaving only the most important ones. I do not store junk like music/photos etc. on this partition, yet it's still jammed, at the worst point reaching only 300mb free space left.
I run glary utilities cleanup every now and then. It's always a max ~1gb gain.
Restore points and system protection are disabled. Hibernation mode is disabled. File indexing is disabled.
The fragmentation of the disk (HDD) has been assessed for 2%.
Windows Update is set to "ask before downloading and installing" for about a month. 
I have run DiskCleanup yesterday and it has found almost 9gb of space to free up. Today after rebooting the pc I've found my C: partition again almost fully loaded, having only 2gb left. DiskCleanup has shown only 30mb of data to be deleted. Glary has found only 500mb of junk.

Your Installer folder looks bloated. Mine is 4 GB with Windows 7. You can't just delete it, it could crash your operating system. You can use tools if you trust them enough.

If you have a backup drive you could just move the files with the tool instead of deleting them. Just in case it causes issues.

Puzzled by the discrepancy between the size of my C Drive and the total of actual folder sizes I ran WinDirStat which has listed the 'missing' disk space as 'Unknown' and is 4.8GB! Any idea what that could be, and where it is?

Answer:Solved: WinDirStat 'Unknown' disk usage on C Drive...

Hidden files, restore points, the MFT, MFT mirror, etc.


Disk Pie
Directory Size Calculator

If that small amount of space is concerning, better get a larger drive.

Please help!!! is there any chance i can fix this?

Answer:Please help,disk 1 unknown not initialized (western digital external)

I guess there is mechanical problem with the hard drive. you can try checking and repairing bad sectors (, or just send it to some drive repair center.
but, if there is important files on the drive, you'll have to recover data before repairing it.

Hello,There must have been a virus on my computer but my antivirus system, NOD32, did not manage to find it.The virus created many many files, which were mostly found in the folder called Recycler under C drive.As a result, around 20 Giga of space were suddenly occupied.I ran the following scans:Ad Aware, and did not find anything at all.Spybot S & D, and did not find anything relevant.Ewido Security Suite brought up the following log (I copy here a part of it, as it is too big):--------------------------------------------------------- ewido anti-malware - Scan report--------------------------------------------------------- + Created on: 11:11:57 πμ, 17/07/06 + Report-Checksum: 2584831A + Scan result: :mozilla.301:C:\RECYCLER\NPROTECT\00264472.MOZ -> TrackingCookie.Hitbox : Cleaned with backup :mozilla.182:C:\RECYCLER\NPROTECT\00267202.MOZ -> TrackingCookie.Valueclick : Cleaned with backup :mozilla.183:C:\RECYCLER\NPROTECT\00267202.MOZ -> TrackingCookie.Overture : Cleaned with backup :mozilla.247:C:\RECYCLER\NPROTECT\00267202.MOZ -> TrackingCookie.Sitestat : Cleaned with backup :mozilla.283:C:\RECYCLER\NPROTECT\00267202.MOZ -> TrackingCookie.Euroclick : Cleaned with backup :mozilla.284:C:\RECYCLER\NPROTECT\00267202.MOZ -> TrackingCookie.Pointroll : Cleaned with backup.286:C:\RECYCLER\NPROTECT\00267202.MOZ -> TrackingCookie.Pointroll : ...

Answer:Unknown Virus Filled My Hard Disk With Files

Hello elzosim and welcome to the BC HijackThis forum. I do not see any signs of viruses or malware in the log. It is clean.It is normal for many files to be in C:\Recycler. This is the folder used by the Recycle Bin. Whenever a file is deleted it is moved to the Recycle Bin so that if it was deleted by mistake it can be recovered (undeleted). Unless the Recycle Bin is emptied regularly there will usually be many files in it. They are stored there until the space that is allocated for the Recycle Bin is used up and then it will automatically delete the oldest files first to make room for any newly deleted files. This is normal.You can manually empty the Recycle Bin by right-clicking on it and choosing Empty Recycly Bin. Some people do this regularly and some never do it. It is up to you.Cheers.OT

Guys please help me to fix my hard disk WD elements 1TB

I have tried so many ways to fix it.. but I got nothing in 4 days!!

I have tried from command prompt " chkdsk /f /r "
the first time I tried it works, but something error occured, and now I can't using that method..
when I tried to using that, just show " cann't open volume for direct access"

my hard disk didn't appear on my computer list, but I can reject it.

and anyway I have tried to using minitool partition wizard, but you all can see that my hdd didn't appear with the volume.. just show up disk 2 with 0.00 GB

Anyone can help me to solving this problem ?

btw, My english isn't good enough..but I hope all of you can understand what I mean

Thanks before.!

Answer:External hard drive disk unknown n not initialized!

Sorry to say your WD Elements is dead and you have tried everything.There is nothing left for me to do, honestly. I would have done the same thing before declaring it dead.. No DIY data recovery is possible. The only option open to you is to entrust it to Western Digital Data Recovery partners in your region. Check with them whether there is any hope of recovering data in good shape.Telephonic consultation is free.
