Windows 7: External HDD is detected but not accessable.

External HDD is detected but not accessable.

Hi,

I've a problem with my external HDD. It's WD 1 My Passport Ultra, 1 TB and I had no problem with it until 4-5 days ago. It's formatted as NTFS and I'm using Windows 7, 32 bit.

Firstly, I couldn't copy files from pc to HDD, couldn't crate a new folder etc. So, I'd tried to do an error-checking. Right clicked onto the HDD, properties, Tools tab, check now, check both then start. I'd waited around 36 hours to complete, but it had stopped around 1/10 of the bar to complete. So, I'd clicked cancel. After that I couldn't access to the files anymore.

The HD light is always bright or blinks, changes. I can see it in the BIOS, device manager, control panel and even Computer without a name, but can't access to the files in it. When it plugged-in, it corrupt my internet and programs like when I scan the pc with antivirus programs.

When I tried to double-click or right click onto the HDD, it shows the circle that indicates loading but nothing happens. If I click other parts of windows explorer, it goes to not responding.

Of course I've tried to unplug and re-plug it, with other USB connections and another computer. Didn't work.
I've tried to scan it with Kaspersky and Avast, couldn't find anything. (Well, avast found 3-4 files then quarantied it but didn't solve the problem.) But I only could scan the pc because when HDD plugged-in, programs have paused.
I've tried SFC /SCANNOW Command - System File Checker , couldn't find any integrity violations.
I've tried to assign a new drive letter for it in disk management, It can't be seen there.
I've tried to uninstall driver in device manager then reboot the computer, it installed the drivers normally, still unaccessable.
I've tried USB Driver - General Fix for Problems, didn't help.
I've read this thread http://www.sevenforums.com/hardware-devices/285134-external-hdd-can-t-open-but-can-partially-detected.html , didn't seem like a shortcut virus when I tried winrar solution.

Can you help me to solve this? Thank you.

If it misbehaves in more than one USB port, I'd download Western Digital's diagnostic tools and see what it says. I think it's called Data Lifeguard. There's a couple of tests---short and extended, something like that. Try the short one first.

Thank you for quick response.

The program couldn't run if the HDD is plugged in, so I unplugget it, still it can't detect the HDD (though it can detect another flash drive) and causes not responding problem for the program.

Were you able to explore the drive and see its contents in WinRAR?

Hi, Erchamion


You have done some pretty good troubleshooting, leaving us with so few suggestions. Do you experience the same issues on the other PC you checked on? I would try defragmentation to see if the situation will get better. In addition I would remove and reinstall the USB controllers. You can find more information in the thread I linked below. You have done the USB fix, but anyway you could find something useful. You can also try the chkdsk/r or chkdsk/f commands. If you have issues running Data Lifeguard Diagnostics, you can try it in DOS mode.
If you get access to your files on your PC or on another, I recommend you to do a backup and format the drive.

Nope. I can't access it. Like windows explorer the loading thing happens, nothing more. If I unplug it, it says "H:\ is not accessible. The parameter is incorrect."



When I click Ok, this message shows up:



And, I don't think that it's a shurtcut virus because the other guy's hdd type on the other thread is "Shortcut", while mine is "Local Disk."

Yes, I experience the same issues on the other PC. But I didn't try the solutions that I'd tried on my pc on it.

I can't access the files from anywhere. These times "Format the disk" message shows up frequently, so If I could have backed up the files, I would have tried it, then formatted the disk.

I'll try those links you've provided. Let's see if there will be anything.

Hi again.

Sorry for taking long. I was trying different options to try the solutions you've provided, but couldn't accomplish.

*Reinstalling usb drives came with same results as before. No changes.

*chkdsk command can't run if hdd is plugged-in. Actually even computer doesn't shut down or windows doesn't start if it's plugged-in. I don't understand this, it corruptsprograms running.

*And for Data Lifeguard program, we need to reboot the computer in order to use it. But, if the hdd is plugged-in, it doesn't reboot, so I need to remove it then select other removable disk in boot options. After that, command prompt opens, I plug the hdd in but it can't be detect by Data Lifeguard.

Hi again,


It is quite unfortunate none of my suggestions helped. I had so much faith in the chkdsk command. Check the latest firmware update from the link I leave below. Apart from that, I fear you don't have many options left. In order to save your data, you should contact a Data Recovery Company. I leave you a link below.
If I were you, I would try one more thing. I have seen many users having luck using Linux live CD, or Ubuntu to make their devices accessible enough to save their data. Sadly, I can not provide you with some Linux guidance, but I can assure you that there is a success chance.

Good luck! I hope you will find a solution

Hi there

If you have a powered USB hub try connecting it to that -- sometimes these drives need a little more power than the computer port alone can supply -- especially on a Laptop.

As far as Linux is concerned download any decent LIVE distro - choose the KDE version since it's almost "More Windows like than Windows" - so you might not have any trouble using it.

Another idea - download the bootable copy of GPARTED - fire it up and see if it recognizes the USB HDD. It has a decent GUI so you shouldn't have any trouble in using it either.

Cheers

Hi, just a novice here, but something that worked for me a few years ago when an external usb drive appeared to fail. I removed it from the original case and put it in a new (USB2) case, which I got from a computer store for about $20. It's been working normally ever since. From what I've read, the "failure" of external usb drives is not uncommonly actually a failure of the enclosure.

Just a thought as a possibility before going to an expensive data retrieval service.
