USB ext 2TB HD saying needs to format (its not new)

#1 Post by CKBW » 07 Mar 2017, 18:32

My 2.0TB WD 3.5" external hard drive I've used for several yrs is suddenly asking to format every time I plug it in (USB).

...so after reading around the internet, I ended up here thinking I need to recover or rebuild the partition?

I downloaded TestDisk and Analysed it (and also went under Advance) to try and view files (to confirm they are still there). After a Quick Search and List Files I get an error that says:

Can't open filesystem. Filesystem seems damaged.

FYI, I am using the default (*) primary bootable characteristics selection on the ext hard drive when trying to view/list the files.
Disk Management on my Win7 64bit PC is showing a health partition and a SMART info on the drive shows no errors.

Any suggestions?

Thank you for any help.

Please post the testdisk.log file content showing what you have done in the Advanced menu.

Will do, I went ahead and started a deep search on the disk (not the recognized drive letter)... scan is at 33% after an hour and 1/2 so far.

after a deep search, I still get the same error when trying to view/list the files.
I have been able to view the files using a GUI file recovery program, but I would like to salvage the partition if possible.

here is the the testdisk.log contents (ext HD in question is: Disk /dev/sdb - 2000 GB / 1862 GiB - CHS 243197 255 63, sector size=512):

If a program can list your files, it's safer to use it to copy your data.
Otherwise using latest 7.1-WIP, you can try TestDisk, Advanced, Boot, Repair MFT.

the problem with the GUI file recovery program I have is that it doesn't remember/contain file location - so I have thousands of files with no directory structure. :(
I'll grab those file today and then try to repair the MFT and let you know what happens, thanks!
