Can't access HDD / Unmountable Boot Volume

[Tamahagane]

I got an "Unmountable Boot Volume" on my system drive. I'm on XP x64.

No use entering in Safe Mode or any other, still get UBV.

I tried following the guide here: http://www.unmountablebootvolumebluescreen.com/

However, it didn't work at all because I don't even get the screen saying "Welcome to Setup", so there's apparently no way for me to get into DOS prompt. I think the reason may be because I'm using a somewhat special version of XP x64.

I put the HDD in another computer. My main goal is to get access to the data on the drive, so I can copy it elsewhere... I don't care if I can't use the drive as the OS disk anymore; I just want to save the files.

I can't access the drive. It shows up, but I can't get in.

When I just click on it once, no info comes up (such as free space etc). If I right-click and check Properties, it says 0 bytes for everything (used, free, capacity).

In the Disk Manager, it says under Status; "Healthy (Active)" and lists the capacity as "139,73 GB" and free space as "139,73 GB" (it's a 150gb WD Raptor, non-Veloci, and not the X / windowed Raptor, but the one without the window; in other words, it's the WD1500ADFD).

I checked it with HD Tune 2.55, and slow-scanned it and 8 blocks are red (damaged).

Is there any way to repair the UBV error? I'm guessing the boot sector is damaged, and that's why I can't access the drive(?). (because it doesn't boot properly to begin with?)

Is there any programs that can help and repair it and/or let me somehow get access to the content to the drive?

I really, really want to save the files on it.

Formatting the drive or otherwise repairing it in a way that the data is lost is not an option. I don't really care about just fixing the drive so I can use it as my OS disk -- what I care about is the information on it. I can and will get a new drive to install the OS on.

Just FYI, the computer which I put the drive in and which I'm using now is a 7-8 year old system with XP 32-bit.

In case you're thinking of suggesting it, then no; there's no way I can afford a professional recovery job.

Please help me out here!

Regarding the guide I linked to at the beginning, I just found this on another forum: "CHKDSK is more likely to mess data up than to fix it. It is good for some things, but when you want to recover data, you don't want to write to the drive at all, with any program." ..... Not sure I'd wanna do that, then... I want to save as much data as possible, very much preferably all of it (because if random parts of the HDD get erased then there's no telling what or how many files get lost).

One problem is with C7. This indicates either your cabling is bad or your SATA port or hard drive electronics are bad.

C5 indicates that there are 10 sectors that the drive has lost because of a URE (drive amnesia). Those probably corresponds to the damaged sectors since nothing is listed as reallocated.

Hmm, I usually see C6 = C5. I do not know why this is different.

I used the program called GetDataBack (for NTFS) and it worked well, I managed to copy all the important stuff (I was lucky that the damaged sectors only effected areas of no importance).

http://www.runtime.org/gdbnt.zip ... it could access the drive and see the contents of it when Windows failed to do so.

As for the HDD itself, why it failed I'm not 100% sure. But I think it was likely either due to moving the computer a bit roughly while it was on, or a weird electrical phenomena that happened during/after a switch on a multi socket extension was turned. However, nothing appeared to happen while the computer was on after it was moved, and the electric switch was turned after the computer had already been turned off, so I'm not sure which caused it or when. The damage may even have occured first when the computer was turned on again, although I find that less likely.

The harddrive didn't fail, you just had 10 bad sectors on it. And some cabling errors as well judging from UDMA CRC Error Count.

You can use Spinrite to recover the damaged sectors, to make a full recovery. After that perform a long format in win7 / zero-write so that the entire surface is clean again. Then the current pending sectors should be gone in your SMART output and the disk could be used for years to come.
