External WD 3TB Raw + Unallocated

#1 Post by thaskasw » 04 Mar 2016, 12:16

Hello there,

First of all tyvm for the awesome tool.

Let me explain my situation. The External HDD had some problem with the power chip (or something) so I removed it from it's original case and moved it to another case. Now the thing is that move messed up the HDD and I see Raw + Unallocated space:

I've followed a couple of guides and I can see the files and all but I just can't seem to be able to fix this :/ After a lot of tries I've managed to see that if I change the sector size from 512 to 4096 I can see everything being OK but after the restart the sector size is back to 512 and in the same situation :/

Here are a few screens and log:

After that I go to Analyze -> Quick Search -> Write -> restart but the sector size is 512 and still raw after the restart..

Any ideas?

I've changed the partition table type into EFI GPT which made all the partitions to merge again.

I changed the sector size to 4096 again but I'm unable to write since I get a "Partition: Write error".

Run TestDisk, keep the same sector size, Advanced, Boot, RebuildBS, List. If you can see your files, choose Write, confirm, Quit and reboot your computer.

If it works, you should run TestDisk again and this time, try EFI GPT, Analyse, Quick Search, List.
If you can see your files, choose Write and confirm, Quit and restart your computer

Thank you for the reply mate. I got an error when I tried that. Will upload a screenshot in a second.

I definitely had a chuckle when I read this post. I am currently having the same problem with the same HDD. Have a western digital 3tb and had a problem with the power adapter. the data transfer port broke, not allowing me to plug my usb data transfer cable into the HDD. ended up taking the HDD out of the case, and plugging sata cables directly into the HDD but now it was asking me to reformat. tried a data recovery program, and it recovered about 10k media files (i have over 50k). now i am running this program and it has been the only program to actually recognize how i had the HDD organized. recognizing file names such as "media, movies, tv shows, etc"... currently copying files and so far so good. everything has been able to be read by the program and has been successfully copied. although, only at about 4k files, so still a lot to go.
