Drive not accessible, shows as "unformatted". Guidance?

#1 Postby dsutton » 16 Mar 2012, 09:06

I have a Western Digital 750gb drive that was working fine until one day it was inaccessible. The computer (windows 7) now tells me that the drive is inaccessible and must be formatted. I don't know what happened, but i have a feeling my data is still intact somewhere on this drive. The windows disk manager shows the partition as "RAW".

I have run testdisk and when I select "Analyse", here's what I see:

Next, I select "Quick Search", and I see this:

I press Enter to continue:

There are limited options with the Extended partition, so I press the down arrow to move to the Logical partition, then select "List". I see this:

Finally, I try the "Boot" option to see what happens:

I didn't take any further action.

Can anyone advise me on what i should do to try to access my data? Thanks.

Did you run Deeper Search in TestDisk?
If your partition was created using windows 7, your partition will be aligned on megabyte boundary.
Those partitions starting after 1 MB.
If an earlier partition was created using intel standard, a remnant can be found and displayed first.

Otherwise, it would look like, that your file system is damaged.
In case, you can try PhotoRec.

Yes, I tried Deeper Scrub. It didn't work.

I just tried PhotoRec, and it is able to recover all my files, albeit without original filenames.

That's better than not getting the files back :)

Thank you Fiona

Try TestDisk, Advanced, select the NTFS partition, Boot, RepairMFT. Maybe you will have access to your files this way.
