I have an external hard drive that I used for back up once upon a time. When I power it up and plug it into my Linux box it comes up as /dev/sdd, with two partitions:
/dev/sdd1 is a EFI system partition, formatted as fat32 and 200MiB. Flags are "boot,esp" but I don't believe I've ever booted from this drive.
/dev/sdd2 has an "unknown" file system and is 76.14 Gig.
There is a message that says "Check and repair file system (fat32) on /dev/sdd1
I did run fsck on each of the partitions... and got this when run on /dev/sdd2:
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>
I'd like to see if I can recover any of the data that's on /dev/sdd2. Can you recommend any tools to repair the file system? Should I try the e2fsck? I am inexperienced and thought I'd ask experts before moving forward.
Thank you.
