NTFS partition vanished from 3TB HDD
Posted: 05 May 2014, 18:51
Hi, I have WD 'Red' HDD with 3TB which I use as storage drive. It contains one NTFS partition (GPT, of course) which spans the whole disc. The computer runs Windows Vista, so larger hard drives aren't a problem.
Yesterday I wanted to connect an older hard drive from a Linux laptop to copy some files. To be able to access an ext4 partition from Windows I installed Paragon Extfs.
After a reboot, however, I noticed that the partition mentioned above simply vanished. Windows drive management only showed a RAW partition which it wanted to format (but I declined, of course).
I then downloaded testdisk and started it. On the first screen I selected the 3TB WDC W30 drive:
Here I already noticed that it only showed 746 GiB, something that only happens if you try to use such a large drive on an OS like Windows XP that doesn't support GPT.
I proceeded and chose 'EFI GPT' on the next screen:
There I selected 'Advanced' and got the following message:
Now I'm a bit unsure what to do and how I can restore the partition or at least save my data.
If someone knows how to proceed at this point I'd be really grateful.
Regards
Chris
