I've tried that but no files are listed.

Ok, I'm assuming that nothing can be done to recover my files. Thanks anyway.

Please let me know if there's any hope left or if I should just cut my losses and move on.
Thanks!

The 1000GB you see listed is an external I've attached for the purposes of cloning.

When I attempt to follow the instructions in your link, I get the error "Segmentation fault" when typing lshw -C disk and when typing fdisk -l, it only shows my flash drive (that I'm booting up from).

My hard drive refused to boot up randomly and isn't able to be mounted. I've been playing around with TestDisk, but when I try to write to the partition, it gives me an error. I've attached my log file.
Any help would be appreciated.
