E525 internal hard drive not detected by BIOS when eSATA drive attached

Question: E525 internal hard drive not detected by BIOS when eSATA drive attached

I have a new E525 that I am trying to use with some external eSATA storage. If I boot the system with the eSATA drive attached, the internal HDD is not found and the system will not boot. I get "Fixed Disk: External Disk 0" on the diagnostic splash screen.If I boot with the eSATA drive turned off, and turn it on once the OS has booted, all is well and both internal and external drives are found.Any ideas? I have looked for a BIOS update but have not been able to find one. I've also been through most of the BIOS settings but can't see anything that looks relevant.

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: E525 internal hard drive not detected by BIOS when eSATA drive attached

It appears that this has something to do with the hard drive ordering. When the machine is switched on with the eSATA drive attached, eSATA becomes SATA HDD0 (presumably the internal drive becomes SATA HDD1).The only option to boot from SATA drives on the boot order menu in the BIOS is SATA HDD0, so it never tries to boot from HDD1 (now the internal drive).I can see this is useful if you WANT to boot from the eSATA, but I don't........

Hi. Just today I finally received my shipment of a WD HDD - Western Digital Caviar Black WD1001FALS 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive and a Rosewill Enclosure - Rosewill RX-358-S

I put the hard drive in, made sure it was in the SATA port, screwed in all the screws, attached it by eSATA and turned it on. My computer doesn't detect it. It's not under device manager or disk management.

Help? :\

Alright, so I have an 1TB Toshiba External Hard Drive and it has the option for either USB or eSATA. I had it attached by USB up til now cuz I didn't have an eSATA cable or port. Today, I went to MicroCenter and got an eSATA to eSATA cable and a port thing that has two eSATA females and two SATA males that go into my SATA ports in my motherboard. I put the two SATA ports in my motherboard, screwed in the two eSATA ports in my case, closed the case, plugged in the eSATA cable to my computer then to my External HDD, turned my computer on, and it doesn't even detect it. Can someone help me out here, please?

I have two WD hard drives with the OS installed on one and the other is for storage. All this started with a hard shut down when the PC froze and then after the restart Windows wouldn't boot at all. It was stuck at the Windows logo for a very long time. Then I checked in BIOS and I noticed the secondary drive was nowhere to be found.

After letting Windows run the automatic repair on the drive the drive showed up in BIOS and I could access two of the three partitions. The third partition threw me an error saying the disk structure is corrupt and unreadable when I tried to open it. In Disk Management the drive showed up as RAW format and healthy. Then I tried to backup whatever I could from the accessible partitions before everything froze.

I rebooted again and right now none of the partitions are visible in Windows and is not detected in BIOS. But in Disk Management it says the Disk 1 is unknown and has to be initialized and asks to initialize with either MBR or GPT partition styles. I've also tried running chkdsk, used EaseUS Recovery and other third party data recovery tools but none of them detect the drive anymore. The drive is however visible on HD Sentinel and it says there are bad sectors and data must be backed up immediately. Does this mean the drive is completely dead? I have over 700GB of invaluable data on it so I don't want to just give up. Any help would be greatly appreciated.

Also, I ran a prescan with HDD Regenerator and it says the MBR is corrupted ... Read more

Answer:Internal hard drive not detected in BIOS after hard shutdown.

Welcome to the TensForum @BlackIce21

Sorry to hear about drive. I think you drive is dead and even if you were to work around getting it operational again, the strain of moving 700GB will likely be a death blow.

If it were me, and the data was invaluable, I would be checking out a credible Data Recovery outfit. Good luck, no body likes losing data.

Hi all ill try describe my problem

I have a sata to esata adapter installed on my desktop but its not spinning up or working my hard drive. The hard drive has 3 ports

Usb to usb
Usb to dc power
Esata to esata

Over usb it works fine but when i use the esata and power cable the hard drive makes a constant ticking noise and isnt detected on windows. Ive double checked inside my motherboard that its plugged into my sata ll port not sata lll. It isnt detected at all by the computer even when i search for new hardware.

This used to work fine over esata on my laptop so it isnt hardware issue

Answer:ESATA hard drive not detected

Esata is tricky sometimes. If you shut down Windows then hook it works I assume. Tell me if I'm wrong. I don't know why they can't get eSATA figured out.

You most likely need drivers for whatever controls your eSATA port. I have had machines that take a lot of work to get the eSATA to work right. You might need to go right to the maker of the chip on the motherboard to get a driver that will hot plug with the machine running.

I have a 7052-B2U M91p with four SATA connectors on the motherboard: two are SATA 6.0, one is SATA 3.0 and one is eSATA.  Two hard drives and one SATA DVD burner use the three SATA connectors.  Is there a straightforward way to employ the eSATA connector for an additional internal hard drive? How is this eSATA connector different from the others, practically speaking? Or was this connector simply meant to power an eSATA connector on a back plate at the rear of the computer? Thanks for your helpfulness. Doug

my situation is the following:

I'm still using Winxp x64 (SP2). My external WD hdd is connected via esata and I regularly switch it on while the computer is running. It is detected by windows within a few seconds. My SATA controller is configured to work in AHCI mode in the BIOS. When I want to switch it off again, I use the HotSwap! Utility to safely remove it (because it is not shown in the native Windows list of removable drives). So far, so good.

Now I installed Windows 7 x64. I try the same thing, but Windows just doesn't detect the drive when I switch it on while the OS is running. It's not even present in the device manager.
It is correctly detected when I switch the external hdd on before powering up the computer.
It is also correctly detected when the following sequence is followed:
1. unplug esata cable and switch off hdd
2. switch on computer and wait until win7 is up and running
3. turn on hdd
4. wait for hdd to spin up (can be heard)
5. plug in esata cable

Then I can also remove it in the Windows removable drive list in the tray icon bar. HOWEVER, when i switch it off again, unplug it, switch it on and plug it in, it is not detected anymore. I have to reboot then. Very strange behaviour.
I also tried the Hotswap! utility and its feature "scan for hardware changes", but it doesn't help.

I plugged in my eSATA drive while CrystalDiskInfo was running and the computer froze. There was no way to regain control of the computer so I restarted.

So now this eSATA drive is not recognized by the computer. The eSATA drive works in another computer.

What's really weird is that another eSATA drive I have works in the computer where the crash happened.

I've tried uninstalling all drivers (both hidden and visible) in Device Manager that relate to the drive.

The eSATA drive also has a USB 2 connection, and that still works fine in both computers.

Answer:eSATA drive not detected--can CrystalDiskInfo damage an eSATA drive


Its unlikely to be the software. The fact that your other eSATA drive works fine, points to a connection issue on the first one. Have you tried swapping the cables?

Hello! Earlier today I bought a brand new 2TB Seagate Internal HDD to replace my temporary 300GB HDD. The first thing I did was connect it to my PC (and other laptops) using USB-to-SATA Adapter. I opened the disk management and the HDD wasn't there, only the drive letter showing up and it says that there's "No Media". After that I connected it to the SATA cable to see if the PC will detect it. Unfortunately, it's still not detected (It says "PXE-E61: Media test failure, check cable, PXE-MOF: Exiting PXE ROM, No bootable device - insert boot disk and press any key". I reinserted the HDD to see if this fix the issue, still no-go. But when I inserted the 300GB HDD the PC detected it as usual.

I don't know what to do now! Need help!

Answer:New Internal Hard Drive Not Detected

You should check if you have purchased a good hard drive but not the defected one. Sometimes it may happen. I assume that because you have connected it to your PC (and other laptops) but the hard drive is not detected.

Alright, so I have a Dell Latitude D630 laptop that's rather old and has several major problems, including never charging, overheating without a small fan next to it, and the occasional key falling off. Well, I was using it a few nights ago and it was working better than usual. Eventually, I turned it off and went to bed. Nothing unusual happened then, but the next day, when I booted it up, it told me the internal hard drive was missing and suggested I reseat it. I ran a diagnostic and it told me basically the same thing but this time it was accompanied by a happy little tune composed of loud beeps, as if to say: "Ha ha, I have found yet another way to ruin your life by becoming even more of an ungrateful mule than I already am, a feat which you thought was impossible but apparently isn't." As of today, when I try to boot it up, it doesn't even show the Dell logo before turning off. This is naturally a tad miffing, but I hope reseating the hard drive will help. Thing is, I don't know how. Any help would be greatly appreciated.

Since you state that you're not allowed to do anything that involves moving the computer or opening the case, there's nothing we can suggest. I was going to suggest you pull the hard drive and try it in another computer with an EIDE/PATA connection (XP doesn't natively support SATA) to see if the other computer detects the drive or to put it in a USB enclosure and connect it to another computer.

I bought a esata-sata cable and tried to connect a esata external hard drive througn a sata 2nd hard drive caddy. The result is that my T42 can not detect the external hard drive. The caddy, cable, and the external hard drive are all functional with other setups. As I know, the signal of esata and sata are the same. It should be just passing through. I don't understand why it fails. I observed that both the leds on the caddy and above the caddy are lighting when I boots T42. However, both leds dims after that. Any suggestion?PS. I know using a pcmcia will be easier. However, several reviews confirmed that the writing speed is limited to 30 MB/s through pcmcia. The writing speed on the caddy is at least 55 MB/s when I tested it with a 2.5 in hard drive.

Hey SevenForums users.

I'm afriad that a Wild Problem has appeared (Sorry for the horrible Pok?mon reference). I have been trying to sort out this problem for days now and I've had no luck what-so-ever. Here's the problem:

My Windows 7 Computer was diagnosed with a dangerous virus. It was stopping Windows 7 from booting. Windows 7 would attempt to boot, it wouldn't get passed the "Starting Windows" screen. Then, it would automatically restart. Then the process would start again. So, I thought 'Why not reinstall Windows 7 since I had the disk with me?!'. That being said, I attempted to reinstall. It wouldn't make it past the "Setup is starting" screen. So, I thought 'This virus must be really bad.'

I decided to install Ubuntu with the sole intention that it would remove the little bugger that was stopping Windows from Booting or installing. It did, but now I wish I haven't. Ubuntu got rid of the virus, and installed successfully. But, now when I want to reinstall Windows 7 back on my laptop. Luckily, it DOES make it past the "Starting Windows" screen and goes into set up as usual. But, I cannot make it past the "Where do you want to install Windows?" screen.

Hi there
I bought an old computer at a garage sale and it had Maxtor 40G hard drive in it (that's what the label says, and it is Model D540X-4K). When I start the computer, I go into bios and it detects it as 204MB hard drive. In addition, when I try to install Windows XP on another drive in the same computer, it says that the 40G hard drive cannot be accessed. I have tried changing the jumper settings into all possible combinations, even upgraded the bios, and it still won't detect the original capacity of the hard drive. I know the hard drive was not removed from the mother board, so it cannot be the jumper settings. Is it possible to retrieve the hard drive in some way? I would like to wipe it clean, and get back my original 40G on it but the bios itself won't recognize it as such. I have the Ultimate Boot CD and have tried using some of its utilities but I haven't had any success with having my bios reading its original capacity.

I don't want to install it in my main computer for fear that my system will crash and I have no other computer to test its capacity within bios. Is there something else I can do? BTW, my computer is COMPAQ Presario 5000 (Model 5UVME2). Any help will be appreciated.

I have a single 80GB drive in the computer. It's set to master (CD is unplugged). Computer boots up and memory test is fine. The bios gets to the "detected IDE devices" and just hangs...and hangs...and hangs. After about 5-6 minutes, the bios will finish it's POST and I'll get "boot disk failure insert system disk and press enter" on the screen. Big deal..that doesn't do much for me, since my hard drive is never recognized.

When I get into the bios, and I try to auto-detect the drive, it never finds it. I've tried all combo of the jumper on the drive too (including cable select). If I have the cd-rom problem there finding it.

I suspect the hard drive is dead (but it gets power because it's nice and warm). What do you guys think? Bios never sees the hard drive (even after I replaced the IDE cable 3x's)....think the drive is dead?

Answer:hard drive is never detected by BIOS

That's one possible reason. Another is that the cable is somehow faulty, or the Motherboard damaged? Is it worth getting a new HD, installing an OS on that, running the suspect drive as a slave, and seeing if BIOS picks it up then? (this may be pointless - i'm new to this lark - but it's what i'd do if i were you).

I found your thread because I have a similar issue, but sounds like mine is more soluble than yours. Rather than hi-jacking your thread I'll post mine on a new thread.

I have a machine that will no longer detect my samsung terra at bios. It seems to make the boot up noise and everything but it wont detect it at all. It does detect my other sammy but not this drive. I tried it in another machine and i get the same problem.

I swapped the circuit board from my working drive to the non working and still nothing. I have quite a bit of data on there if i can get it to boot that would be great and copy it all over.

Before this happened every now and then when i turned the machine on it would not show it as being detected. If i powered off the system a few times and turned it on it would come back, i thought it might be because it was Pentium 4 and it was old and dying but when i put it in my i3 it doesnt work.

Answer:Hard drive not detected at bios

Is this a SATA drive (probably)? You didn't provide any specifics on the hardware.

Have you tried moving the SATA cable to a different connector on the motherboard? I know you said you tried it in another machine, so that would suggest the drive itself is the problem... but still...

Try using a different SATA connector on the motherboard, and maybe even another SATA data cable.

Pull out the data cable and re-seat it, both on the drive and also on the motherboard.

I had a recent similar situation with a Western Digital Velociraptor drive, that I thought was going bad. Like you, I would try all kinds of different ways to coax it back to "normal operation", and mostly they would work. Eventually, I decided to replace it.

I ordered a new one, transferred the contents, and it all seemed to work perfectly, pointing to the old drive as the culprit. Then two weeks later the new drive began to act up again, just like the old drive had. Grrr..

Anyway, I decided that maybe it was my SATA #4 connector on the motherboard that was at fault. So I moved the cable over to the SATA #2 connector... and it's been perfect ever since (fingers crossed that this holds true forever).

Hi. I have looked through some other articles here at TechSpot relating to non-detected hard drives but did not find this peculiar issue. After four months of running just fine,n suddenly the hard drive is not detected in the BIOS but sometimes the Windows logo comes up (it has to see the hard drive from somewhere!) but does not open the operating system.

COMPUTER SPECS--all components were purchased four months ago:
Motherboard: ASUS M2A-VM, a low to mid-range board
DRAM 3 GB Ultra Dual-channel
Power supply: Thermaltake TR2-R1 450-watt
Processor: AMD Athlon 64 2GH
Hard drive: Seagate Barracuda 320 GB 72 RPM (Nice!)

I tried a different power supply unit.
I ran the Windows CD, pressed R, and it declared that no disk was found.
I ran the Ultimate Boot Disk and it did not see the hard disk.
I connected the hard disk to an MSI motherboard, ran the BIOS, and it detected the hard disk. I did not run Windows as I knew Microsoft would not see it as the original motherboard.

The BIOS on the ASUS computer does not have a listing or selection for PATA. It just has IDE (the DVD drive) and four SATA connections. The hard drive is not detected but it is on SATA connection #1.

I suspect a failed hard drive which is surprising since it's a Seagate. I don't have another SATA hard disk to test that idea with. I haven't tried clearing the CMOS, either, but at this point, I'm not sure what good that would do.

Hard drive not detected by Windows or BIOS [SOLVED]

I know this is has been addressed before; however, the responses did not solve my issue. I will include more detail about my issue in hopes of a better diagnoses.

I accidentally changed my external hard drive from NTFS to HFS when prompted, while connecting via USB to a macbook. Now I can no longer see the hard drive via USB or direct connection to my PC.

I took it out it's case and noticed it has an IDE connection for a motherboard that only has SATA connections. I purchased an IDE to SATA Adapter and installed it into my computer.......nothing. The BIOS and Windows still does not see this drive.

I am aware I have two separate issues. In order to correct the file structure issue I have to gain access to the drive.



The hard drive powers up both in the external case and with the adapter.

Answer:Hard drive not detected in bios or my computer

Hi ally1956

Recheck the drives jumpers and try a different IDE cable. Its possible that the drive has just died. Try downloading the manufacturers drive test and running that. Is the drive under a warranty?

Answer:Laptop hard drive not detected in BIOS

It's very possible your HD is dead.
You can try re-seating it, or test it on another computer via enclosure or USB adapter, but you probably need a new drive.

Yesterday, my motherboard keeled over and died on me, so I went out and bought another one for my PC. I put it in and hooked everything up correctly according to the manual. My computer starts up, and it stays on the mainboard screen (the one where it says "press <tab> to show POST" and "press <DEL> to enter setup") and does not leave this screen. So I decide to go into the BIOS setup. In the BIOS setup, and look at the boot order. My optical drive is there as SATA2, but my hard drive is nowhere to be found.

I turned it off and reset the BIOS in hopes that it would fix the problem to no avail. Upon closer inspection, however, I found that the hard drive DOES in fact spin for a few seconds, only to stop as soon as the mainboard logo screen shows up.

I have plugged my hard drive into my brother's computer as a secondary drive, and all my files show, so I know the hard drive is not completely faulty. Does anybody know how to solve this problem? If so, please help!

Here are my specs, in case they help:
Motherboard: MSI K9N6PGM2-V2 AM2+
CPU: AMD Windsor 6400+ @ 3.2 Ghz
HDD: Western Digital Caviar Blue 320GB
Video Card: nVidia GeForce 9800 GT @ 1GB

Hello guys,
I have 60 GB maxtor hard drive. it had two primary partitions with dual boot,
one is WinME and the other was XP. it had lot of unwanted programs from my friend and was not working well.
my friend had assembled it with AMD 1.8 GhZ, 512 MB RAM.

I bought a new XP pro software and decided to have a clean install.
used GDISK( similar to FDISK) to delete all partitions.
then i put the XP CD to create partition and load XP, it said no HDD found.

i did not open the box nor distrub the box.
i did the following in the sequence i have stated.
I copied all the data files into CD.
then i put the GDISK to delete all partitions.
then put the XP cd and boot from CD,
XP setup comes up and it is unable to identify the HDD, so everything else
stops. everything was working before suddenly after delete of partitions,
HDD could not be detected by BIOS.

then i looked into setup while booting,
the CMOS standard does not identify HDD.
it had the following identified in SETUP - CMOS standard
Primary master: DVD rom - ( i set this in AUTO and press ENTER it identifies
Primary Slave: no installed ( i set this to AUTO and press ENTER- it says
not installed.
Secondary master: CD ROM
Secondary slave: not installed.

it detects Floppy drive.

any ideas..
thanks in advance..

Hi, I'm hoping someone can help me with this problem. I have two WD SATA drives (WD3200AAKS & WD6400AAKS) which have worked fine for a few months. Now I'm trying to install a third SATA drive (another WD6400AAKS).
BIOS detects it on IDE Channel 2 (Master) with correct specs. AHCI and RAID are disabled. During bootup, I can see all 3 drives detected at POST.
My problem is that Windows XP doesn't detect the third drive. When I go to Computer Management > Disk Manager, there's no sign of the drive. I see no way to format it.
Any help would be greatly appreciated.

Answer:3rd Hard Drive detected in BIOS but NOT in Windows

Is this drive right out of the box?
That is to say, un-partitioned and un-formatted?

I have never, ever, presented a new hard drive to Windows without first booting the system up to DOS and partitioning and formatting the drive.

For safety, the new drive should be the only one connected during this process, so you don't wind up formatting your OS drive.

If your SATA port on your mobo is SATA2, then make sure that the SATA1 jumper on the back of the drive is REMOVED. Otherwise, the drive will NOT be seen. IT's a minor detail, but it's already bit a bunch of people in the pants.

I use my Windows ME boot disk to FDISK and Format every hard drive I get before I ever present it to Windows XP.
But then, I use nothing but FAT-32 for all my drives.

Even if you set up a drive as FAT-32, in Windows there's a Utility to convert it to NTFS, if that's what you want.

Almost an afterthought.......make sure the data cables are TIGHT.
They have a real bad habit of working loose. I fasten all my SATA cables to my drives with HOT GLUE, so they can't come loose.

Good Luck,
The Shadow :cool

Im re-using my current 750gb SATA drive.
I plugged it into the sata port, and start the computer.

When it starts it says "no hard drive is detected!"

I go into the bios, and on the bottom it has a disk drive, and a SATA drive.
It recognizes that the sata drive is there, but when i go to start up it says no hard drive is detected.

I have tried a few different sata ports and it is the exact same thing.

I'm a bit kind of desperate now. I purchased a 2TB Western Digital Sata drive (WD20EARS) and an enclosure with USB2 and eSata interface (independent power supply). Everything was ok for almost 2 months till today it just suddenly stopped being detected at all.

I wasn't doing anything in particular when this happened. I remember I restarted my laptop around the time this happened (I do not remember if it happened before or after this). Any idea what could be wrong?

When I attach it with the eSata cable, nothing happens. With USB, I hear the beep that "something" was attached but then again nothing. Nothing at all in Device Managre or Storage Management.

Any ideas, please let me know... I'd appreciate it. Thank you.

I have had my Toshiba Satellite Pro P200D-10P for 3 years now and have had a recurring problem. If I shut it down for any reason I then cannot reboot it thereafter, sometimes for several hours and at worst for several days. In BIOS, under 'Main' it has 'None' under the 'Hard Disk' title. If I try and boot it up I get the error; 'For Realtek RTL8100E/8101E Fast Ethernet Network Adapter v1.02 (060529). PXE-E61: 'Media test failure, check cable. PXE-M0F: Exiting PXE ROM.' I assume this is due to no hard drive being found in the boot sequence and LAN being used.

I have updated the version of BIOS to v1.07 and have tried removing each of the 1GB RAM to check if its due to bad RAM but that has not helped the issue.

I have removed and replaced the hard drive to ensure it is seated properly but that has not improved the problem.

Hi all,
I am attempting to install Win7 in an Inspiron 1545 with a new SATA hard drive that was purchased. When i insert the drive, I get "Internal Hard Disk Drive Not Found." I have verified the drive is not showing in the BIOS, I've already attempted to reseat the drive several times. In addition, I've attempted to load the chipset drivers, SATA drivers, etc from Dells website, the drive still does not show in the OS install when booting to DVD or in bios.
I dont believe it to be an issue with the new drive, as I plugged the new drive into another model Dell laptop and it recognizes the drive fine in BIOS, also I can still boot to the previous hard drive in this laptop without issue when i plug it back in.
Is there a specific driver, etc that I need to use for the drive to be recognized or other thoughts people have?

Answer:Inspiron 1545- replacing hard drive, new SATA drive not found "Internal Hard Disk Drive Not Found

This is strange - either the new hard drive has a rare compatibility issue with your onboard controller (I use a 500Gbyte in my 1545 without probs)) or it is a mechanical problem.I would take a close look at the physical dimensions and compare your original hdd with the new one.Watch the video (even though it's about a 1525 (similar to an 1545) and an SSD hdd) -  go to 2:20

Answer:?Will attaching primary drive via eSata, result in less fan sound? (due to less internal heat)

<<Will connecting the primary SolidStateDrive via eSata, reduce internal temps significantly, and would that result in slower/quieter fan speeds?>> No.  Your hands resting on the laptop will transmit more heat to the laptop than an SSD installed inside.  Manufacturers don't even test or run heat profiles on them anymore because the heat output is negligible.  <<Can an external SolidStateDrive be cooled passively, just sitting in the open?>> SSDs don't need active cooling.  They're tested at the design stage in ovens that are way hotter than any temps that your laptop will reach inside for it to still be functional. Don't worry.  Be happy.

Lots of BSOD, lock ups, hard drive not being detected by bios, is it failing?

Let me start by saying my PC is custom built, most parts are only a year old.

The oldest parts are the harddrive (about 5 years) and the soundcard (about 7 years).

I have never had major problems until now (a year after building it).

It all started with a blue screen.
Reboot windows and it seems to start up fine, gets to the desktop and locks up.

Reboot windows and I get another blue screen.

I Try to start windows from the last good configuration.
Error. Registry file failure. Cannot load hive file.

I try booting from the windows cd and running a chkdsk.
Harddrive starts making a buzzing sound.
It gets to step 3 of 5 and stops.
Failed to transfer logged messages. Status 50

Now the bios rarely even "sees" the drive.
When I can get it to boot and see it, any attempt at diagnostics and repairs produces errors, locks up, or fails.

Is this a bad harddrive? I would hate to spend the money on a new one only to find it is a bad mobo or virus.

How can I diagnose this? If it is a bad drive I would like to save what juice is left in it and try to recover a few files before it dies.

Most of the important data has been backed up but I would like to try and get a few game save files if I can.

But its not a disaster if the drive data is not recoverable.

Thanks for any help in advance.

I went into BIOS to see the Hard Drive status but i can't see any option where the HD is detected (so i assume it is not being detected).

I thought this issue meant the HD must be the problem. However, i took the HD out of the Advent & tried it on another laptop and it worked fine. Also, i used the working lapyops HD to test the Advent Atom laptop & i get the same error - even though the HD i tried is a perfectly working one.

I have checked to see if the hard drive has power going to it & i can hear it spinning.
I have tried the recovery CDs but they won't install (assuiming thatw ithout a drive, the recovery software can't install).
The hard drives in question are SATA drives

Can anyone please help me with this issue?

My Dell laptop is displaying this message upon booting up. I have no idea how to start fixing it or figuring out whether it is fixable.

My dell charger is worn out, and the computer has not recognized it -- it still gets power to the computer, but the computer does not recognize it as a dell charger, and therefor I can run the computer on AC power but it cannot charge. I haven't needed to use my laptop out of my house in awhile so I haven't really worried about it, but can the fact that the battery has been totally drained for awhile (about a week, I think -- and totally drained, if I unplug the charger it turns off immediately) have something to do with it? I have it on a working charger right now trying to revive the battery, but the battery light is not on so I don't think it's even charging.

If trying to charge it doesn't help, what do I do? I can still run setup and the boot menu but I have no idea what to do when running these.

Answer:HDD Error - "Internal Hard Drive not detected"

"My dell charger is worn out, and the computer has not recognized it"...

Your post is confusing. Are you talking about the AC adapter (charger) here? If the charger isn't being recognized by the laptop, how is the charger able to power the laptop?

The laptops internal battery is probably dead. They don't last forever. What about this " HDD Error - "Internal Hard Drive not detected"...?"

This means that there is something seriously wrong with the hard drive. This hard drive stores all your data, pictures, email and Operating System

Please help

Answer:eSATA Drive Windows 10 and BIOS

What system are you using, and are you trying to use an eSATA port built onto the system or a dock?  As far as I know, eSATA ports are typically controlled by the motherboard's own SATA controller, so you wouldn't need additional drivers, though it may help to have the latest Intel Rapid Storage driver. However, if even the BIOS isn't seeing the drive, you might have a problem below the OS layer anyway.

I just got a new Gigabyte GA-P55A-UD4P motherboard, and I am trying to get Windows 7 64-bit to recognize an external hard drive connected to the eSATA ports.

I've set the the following BIOS options:
PCH SATA Control Mode to AHCI
HPET Mode to 64-bit
eSATA Controller Enabled
eSATA Ctrl Mode to AHCI
GSATA Controller Enabled
GSATA Ctrl Mode to AHCI

When I first connected drive the motherboard, a tray icon said that I needed to install a driver to get the hard drive to be recognized. So I went to the device manager, and under other devices there was a device titled JMicron something (sadly, I don't remember exactly what it was titled). So I placed the driver disc in the optical driver, and I had the missing device search for the driver on the driver disc. The device manager found the driver, and new device came up as JMicron SATA something (again, I don't exactly remember what it was titled). So I restarted, then I powered on my external hard drive, but Windows still didn't recognize it. If I try turning on the external drive before I boot-up my system the drive still isn't being recognized by Windows.

The drive does get recognized by the BIOS on start-up if I power on the external drive before I boot-up my system. So that tells me that the BIOS is detecting it correctly; and the problems is with Windows.

So where do I go from here?

Answer:Windows 7 not recognizing eSATA drive, but BIOS is

The GA-P55A-UD4P has 2 eSATA ports in the rear on the motherboard. Are you plugged into those, or are you using the eSATA port on your case?

The case connectors usually plug into the JMicron Controller, but the rear ports should be on the mainboard SATA controller. If you haven't tried already, try using the rear ports and test.

In my web travels I've notice a lot of posts describing issue with eSATA cables. It seems quality cables are a must. I've even seen where some folks have had to cut up to 3mm of plastic casing off the plug top get a connection to work.

Can you see if the eSATA drive can be recognized, using the same cable you are using now, on someone's else's computer?

I have a 2TB Western Digital My Book Essentials, it's filled with tons of old photos, movies, docs, games, and I'm scared to think of what else. The SATA to USB connector broke on it, so I took the drive apart and put it inside my computer. I opened up device manager because it wasn't showing up automatically and the 2TB is showing up as unallocated, I'm freaking out now because I'm scared the data was somehow deleted.

What do I do?

edit: I realize also this isn't directly related to Windows 8 (besides the fact it's the OS I'm on), but I don't know where else to post it. I'd also like to say that I had a really deep feeling the drive was going to break continually for about two weeks before it happened, so if you have a similar feeling about something, don't ignore it!

Answer:External hard drive shell broke, salvaged internal drive

As long as your hard disk is still spinning & recognized by Windows, the data in your hard disk is still there, just the File Allocation Table got corrupted, You'll have a good chance to recover your data. What you need is a data recovery program, I use this program in the past:

Data Recovery Software Products - Runtime Software Products

In the mean time, leave this hard disk alone, do not initialize or format it when Windows offers to do so.

Answer:750 GB 2.5 Inch 7200RPM Momentus XT Solid State Hybrid Drive Internal Hard Drive

There isn't a simple answer. This drive has 4K sectors, (advanced format) so the answer (yes/no) depends on what operating system and service packs you are running and how you intend to load your OS/data to the new drive

I have Vista Home Premium with two 320 GB internal hard drives © & (E). I am trying to put Vista on drive E and upgrade to Windows 7 on drive C.
I had successfully cloned the drive C of Vista onto an external hard drive and copied it to drive E (the second internal hard drive). When I copied the cloned copy of Vista to drive E, the system changed the drive letter to L. Everything was working fine and I could boot into either C or L.
In a fit of neatness I guess, I decided that I would like to have the newly labeled drive L designated as drive E again and changed it to drive E in "Disk Management" while I was booted into drive C.
Now I am unable to boot into the second internal drive. I just get a blank screen. I can get "Task Manager" but nothing else, not even the "Start" icon.
I booted back into C and changed the drive back to L, but that didn't work either.
I tried to boot the second internal drive in Safe Mode, but just got a blank screen, without the start icon.
I tried restoring to a previous date, but that wouldn't work and it only restores C anyway.
When I'm booted in drive C, it shows the second internal drive L and shows all the files and programs that should be on drive L.
How do I get the drive restored so I can boot into it?
Thanks to anyone that can help.

Answer:can't boot to second internal hard drive after changing drive letter

I don't know if this helps, but is drive L still marked as an "active" partition in disk management?  When you right click the partition the option should be there to do so if it is not marked as such.

hi , i have this problem whereby whenever i resume the computer from sleep, the dvd drive disappear from "my computer" and device manager. It could not be detected as well. All the hard disks were detected.

The only way was to restart the computer.

The dvd drive is connected via the IDE cable to the mobo , using the Jmicron IDE/Raid chipset.

may i know if there is any remedy to this ?

Thanks !

Answer:internal dvd drive not detected.

I experienced a similar issue, only instead of my dvd drive not being detected, when I woke up my computer from sleep mode my wireless pci adapter wasn't detected, and I had to restart the computer, and then it was fine. Only thing I can recommend is to make sure you have the latest drivers for anything you may have under IDE in device manager, and your dvd drive, only other thing I can recommend is to disable sleep mode if noone can provide a solution to your problem;(Right click your desktop, click personalize, click screen saver, towards the bottom click the blue link called 'change power settings', click your preferred plan, and set "Put the computer to sleep"; to 'Never') Hope that helps, but hopefully someone can provide a better solution for you.

Hey lads

I recently got a new WD MyBook2 and 2 esata cables for it and my other external HDD (Seagate FreeAgent).
Not sure if it's worth mentioning but my motherboard is a MSI P7N Platinum.

The MyBook isn't being found at all when connected by esata but works fine with USB. When connected by esata it isn't being found either in the BIOS or device manager/disk manager.

The first time I connected the FreeAgent it recognised it but it was transferring at USB speeds. It wasn't appearing in the BIOS either though.

I've tried different things, like changing the esata controller in the BIOS from IDE to AHCI and RAID. Neither of these worked and when I booted up I got a message saying xInsIDEx.exe has stopped working.

I've also tried plugging in the esata cables before boot and after boot and neither make a difference.

For the moment I've settled on USB but would love to get them working with esata but I'm stumped.

Any help would be greatly appreciated.

Two SATA 320 GB internal drives connected to SATA slots 1 and 2 of 4
An external ASUS eSATA and USB2 enclosure with WD 640 GB SATA hard drive connected to an eSATA port on the computer.

The external eSATA hard drive works fine after a reboot but after a few hours it vanishes and cannot be found by Explorer or the Control panel even though it has not been accessed to modify, delete or add files. A reboot finds the drive and it works again for a while.

I have an eSATA backplate port connected to slot 3 on the mobo. The mobo also has an integral eSATA port on the back. The problem occurs when I connect the external drive to either of these ports.

The external enclosure also has a USB2 connection - if I use this the problem does not occur indicating that the hard drive itself is OK.

Any suggestions?

I earlier posted about the Aspire AST690-UP925A having 250GB hard drive. I since then contacted Aspire chat support. Apparently, not being tech savy we didn't realize 250 gb hard drive only 112 c drive is able to be used, the d data drive holds the programs to run the computer.

I didn't mean can I use the external hard drive internally. I meant, if I hook it up externally would it work in place of the internal hard drive that is nearly full except for around 10 GB?

So, unfortunately the computer isn't as big as you believe. But...I wanted to know if I purchase (I was looking at western digital elements 2TB external hard drive). Can we use it for this computer. It will not run itunes or anything like that, but we can obviously go online.

My brother wants to buy a new computer, but I know that is probably not the way to go. Should we get an internal hard drive installed and other memory or something or can we use the external hard drive?

I would appreciate any informed help on this since we do not no technical info on computers. Can't really afford to buy another computer right now.

Thanks in advance

Answer:Can external hard drive be used for full internal hard drive?

If you want to take out the drive from external hard drive case and install it in your desktop/laptop, then usually you can. Usually external hard drives are just ordinary hard drives accompanied by some extra controller to make it able to "talk" via general ports (e.g. USB). However I am not familiar with digital elements 2TB , so I can not confirm it. But I do have WD external drive, which I had positively confirm that its real drive is just ordinary hard drive.

Note that if you decide to do this, I suggest to find experience people to work on extracting the drive. If you do it yourself you will risk to damage it, and you don't want that since usually opening the closure means voiding the warranty.

I am unsure about what happens after you convert your internal hard drive to an external hard drive... Let's say the internal HDD was your only laptop HDD and you replaced it with a SSD. If you convert your old internal HDD to an external HDD, what would happen when you open it up on your newly installed OS (on the SSD)?

I am trying to download a new OS but us my old internal HDD as an external drive just to access specific files. However, I don't want any other data/programs/settings/etc. downloaded onto my new SSD. Do I need to delete my old OS when I convert my old internal HDD into an external HDD or does the OS simply get "reduced" to a bunch of files that I will see on my newly installed OS?

If anyone is able to clarify these questions that would be fantastic!

Hi guys,

I'm new on any sort of forums so go easy if it's a stupid question..but here goes.

Me and my brother built me a new computer from scratch (he did the building - i did the watching).

To cut a long story short - I purchased an internal hard drive from Overclockers UK. It's a Samsung 1TB drive. I also have a 64 Solid-state drive in there as my primary hard drive that Windows was installed on and a couple of programs are installed on. My storage disk (the 1TB disk) is for all my music/films etc. Whenever I drag and drop a file into the Samsung hard-drive - it copies it rather than moves it instantly.

When I had a laptop, I had 3 external hard drives and this is the way it copied files onto them.

Does anyone know how I can get the internal drive to stop acting like an external drive?

Any help would be greatly appreciated.

Answer:Internal Hard Drive acting like an External Hard Drive

This is the way it works. I have an 80GB SSD and an internal HDD and the same happens if the file/folder is large enough. If you just copy a few MBs, you will not see the window with the green stripe running. But if e.g. you copy 500MBs, you will see it. It physically moves the data. That is different if you copy on the same volume from one folder to another. Then it only makes an entry in the MFT.

Sometimes the eSATA port has to be enabled in BIOS. And some eSATA ports require that the drive be attached and powered on when booting the system. This is particularly true if you aren't running your hard drives in AHCI mode.

If your system doesnt want to boot off the CD or DVD drive go into bios and set the CD or DVD drive as 1rst boot device in boot order. Once you successfully boot off of your optical drive you then can delete the partition on the hard drive, create new partition and reformat, then install clean installation to that hard drive. If you dont have recovery or oem cd available, you will have to buy one.

My motherboard is ASRock m3a770de. I built my machine 3 days ago. I have one Hiatchi 500gb internal HD, and one 1TB external HD.

I am running Windows 7 x64 Ultimate Edition.

After building my computer three days ago, I installed windows, and my external was not being detected through eSATA in the BIOS or in Windows "Probably need to install drivers" I said.

So I put in the CD that came with my motherboard, and installed the AMD All in One Driver that was on it. Restarted, and hey, my external was showing up.

Today, after installing SP1 (not sure if thats what did it), my ext hd was no longer showing up again. I reinstalled the driver on that CD. Now, I'm not sure if it even installed the first time, because it said it was currently uninstalled through the ATI catalyst installation program. But it didn't work this time. I'm not sure what got it to work the first time. But my eSATA drive was being read in IDE mode for three days. When trying to get it work the first time, I did plug it in via USB to see if it would work, maybe that had something to do with it working the first time?

Anyway, I changed my registry to start up in AHCI mode, and then went into my bios and changed my storage config to AHCI. Upon booting, windows would not load with my external HD turned on (anybody know why?), but loaded once I turned it off. Windows then installed AHCI drivers, and upon restarting, both hard drive, external and internal, were being detected as removal ... Read more

Had a dual-boot system (Win 7 on drive 1, XP on drive 2) installed. Got an NTLDR is missing error on the primary WD drive on which Win 7 was installed. XP wouldn't boot either because the MBR is on the primary drive. So, I had to reinstall XP and all the software on the 2nd drive and test in original and another computer. Worked fine. When plugged into the motherboard, the Win 7 eSATA drive is not recognized by either of the 2 computers in the BIOS. It won't boot and I can't even look at the drive to see the contents - it's a non-entity as far as Windows is concerned. I plugged it into a Mac with an external eSATA to USB adapter and the Mac saw the drive but said that it was unreadable and asked if I wanted to format the drive. Since I thought I might want to try to recover files, I didn't. Anyway to see the contents of this drive with Windows and recover them or does it seem to be dead from the description?

I had  a virus on my toshiba laptop L305-S5877.  So I reloaded the OS, and everything seemed to be going well, until the desktop showed after the install was completed.  I noticed that in my task bar, there was that icon that you normally get when you plug in a usb device.  And I clicked on it to find out that the device that was listed was my internal hard drive.  Why is it doing this and how do I fix it? 
Also I noticed that when I plug in an external hard drive or anything into a usb port, it is not recognized and I dont hear the familiar sound or see the device as being plugged in.  Whats going on

My brother bought a new internal 500GB hard drive a few months ago and saved all of our family photos to it. Well a few days ago he noticed it would not show up as a hard drive in 'My Computer'. If we go to 'Disk Management' the 500GB hard drive shows up without a drive letter and is marked as a Recovery Partition. Does this mean we lost all of our family photos that were on the hard drive?

If you need more information feel free to ask. I'll attach a photo of what i mean.

Answer:Internal Hard Drive does not have a drive letter but used to.

Welcome to Seven Forums BinaryMadman

The 500GB drive should not be listed as drive 0. shut down the system and swap the motherboard connectors on each drive. Let us know how that effects things for you. Go back to Disk Management, right click the drive in the bottom pane, Assign Drive leter (any will do).
