Corrupted Disk Using PowerQuest Drive Image 7!!

[FFF]

Sh*t! I was attempting to backup an entire 80GB drive tonight using
PowerQuest Drive Image 7. Somehow, around 10% through, the application said
that it ran out of space on the destination drive. I was sure there was
enough space there but that is another problem I will work out later. The
more serious problem now is that the drive I was attempting to back up can
no longer be read at all! :-(

When click on the drive in Windows Explorer, I get the error dialog "F:\ is
not accessible. The file or directory is corrupted and unreadable." The
Microsoft site says that the MFT or FAT is damaged and I should try chkdsk
/f on it.

http://support.microsoft.com/?kbid=176646

What the hell happened? Why was Drive Image 7 *writing* to the source
drive's MFT for??? The data in this drive is absolutely precious and worth
years of work! AAAARGH!! I feel liking punch the wall right now! I have
*not* run "chkdsk /f" on this drive yet until I find out some more info.

I have tried plugging this drive into another computer and I get the same
error! Pleaese HELP!!!

BTW, just be clear, this drive has a single NTFS extended partition that is
76GB in size. Still searching the net for a solution but nothing conclusive
yet... :~(

To provide additional information, you can download Findpart at

http://inet.uni2.dk/~svolaf/utilities.htm

do:

findpart all fp.txt

and insert (not attach) the output here.

Hi Svend. Thanks for the link and the program! The output you requested is
pasted in below.

The output is not complete, since we do not see the partition tables
on the disk.

Do this:

findpart 3 -fat fp-a.txt

The search may take some minutes to finish.

From the description of the problem, one possible explanation can be
bad sectors in the partition. If the search takes long time, or you
hear some unusual sounds from read retry attempts, you can stop the
search. In that case, the preferred method may be to initially copy
the entire problem disk sector by sector to a new disk.

Oops, okay I have the entire output now using the command findpart 3 -fat
fp-a.txt. See pasted text below.

There are no visible problems in the partition tables or boot sector.

If you have room for all files in another partition in the system, the
Findpart command to attempt to copy all files to current directory and
below will be (assuming the problem disk is disk number 3):

findpart findntfs 3 1 1 1 copy

or to initially make a file listing for your own use:

findpart findntfs 3 1 1 1 files files.txt


Alternatively you can:

1. Examine the disk for bad sectors. The command will be:

findpart findbad 3 fp-b.txt

or in pure DOS using the Findbad program from my page (faster and more
reliable, assuming the disk number is the same in pure DOS):

findbad 3 fp-c.txt

or

2. Get a new disk and initially copy the problem disk sector by sector
to the new disk. If you want help to that, you can mail me.

Found some awesome little tools that should help me copy out the data from
this corrupted drive. I tried demos of File Recovery 3.0 and Stellar
Phoenix and, from what I see, they will let me copy out all the data.

I think its all okay now once I buy one of full versions of these tools.
That was a close one!
