I'm not sure if this is the right forum, but I figure it's a good start.
I had to use my external hard drive enclosure for another hard drive than the one normally in there, and after I put the hard drive back in, I went to get some data off of it. I plugged it into the enclosure, plugged the enclosure into the computer, and nothing happened, no drives mounted.
In gparted, the entire drive is listed as "unallocated." I cannot remember the file system structure, but I had one ext4 partition with a Linux OS on it, another ext4 partition for the majority of my files, and an NTFS partition for Windows backup.
Any thoughts on bringing back the filesystem and the files?
