No idea what caused it, does look a bit like what happened in the past when you moved files around on NTFS drives, at some stage they got messed up so you had to copy the files to a FAT 32 drive which fixed it, can't remember the reason because of it but after that you can copy the files to your usual drive again and they would be fine.
I've got an old Athlon 64 Dual core machine which was living inside a huge ass Chiefteccase, since it is micro ATX I decided to take the stuff out, clean it and then cram it inside a really small Asus micro ATX casing.. ye gods, cable management was a struggle, PSU is an Antec Eartwatts 380, it came in a Antec HTPC casing, all leads are 15cm longer than those on a normal PSU so cable management was like fighting an octopus..
