So I had a customer come in for data restoration when they had an installation fail which resulted in partial data loss.

When booting into a live USB on the machine the drive shows up with lsblk as the correct size for the actual drive, df can find the drive but shows the partition as 7.8G instead of the true ~120G.

Here is the results of lsblk

sdc      8:32   0 119.2G  0 disk

And here is the result of df -h dev/sdc

Filesystem      Size  Used Avail Use% Mounted on
udev            7.8G     0  7.8G   0% /dev

Is it possible to either mount the drive or just browse the files to see what I can recover before properly formatting the drive and reinstalling the OS?

    Maybe, maybe not. Depends on whether the filesystem is corrupted.

  • You might consider using dd to make a copy, if you can. Then, in an emergency, you can do aggressive experiments. I've had to emacs a (copy of a) swap file before to recover data. It worked, but it was a (really) long shot.
