On Friday night, I was trying to upgrade my 64-bit installation of Mint from 12 to 13, through APT. Yes, I know this was a bad decision, but hindsight is 20/20. I should also point out here that I'm a relative newbie to Linux, having limited experience with Ubuntu in the past few years.
Unfortunately, the process was interrupted by the computer shutting down. Before I was able to back up my important files, which were essentially just my Pictures folder. As I expected, my machine wasn't able to boot up at all, so I had to use the LiveCD on a USB drive to try to save my data. For some reason, however, I wasn't able to access the computer's Home directory, and when I tried to open it as an administrator, it said it was separated to another partition to preserve the data, which appears to be just the main partition. It didn't make much sense to me, but I can transcribe it here if need be.
Anyway, after doing some research on my situation, I downloaded Testdisk on my LiveCD and used PhotoRec to try to recover my files, and after four hours all 172,684 .gif, .jpg, and .png files on my hard drive were recovered, which is obviously a heck of a lot more than what I was expecting.
I suppose what I'm trying to ask is, is there any other conceivable way I can back up my Pictures through the LiveCD, or was this about it? I'm not exactly looking forward to sorting through all these images, but it is most certainly better than losing them all.
