File system corruption?
What file system do you have? If it is something with a journal (ext4, for example) I would be surprised. If it is something experimental or less reliable (btfs, reiserfs?) then I wouldn't be surprised.
All file systems can lose data if you interrupt them while updating the file system, but some are more resiliant than others. I tend to prefer the good old ext3 or ext4 standby over flashier, faster but less resiliant newer file systems, and older, unjournaled file systems like ext2.
Have a look inside /lost+found (assuming /usr/bin is in the / partition) and see if there's anything there. You may find all your X files, and more, given generic names. Or you may find nothing at all.
Or unsynced RAID cache - I had it once.
No raids on the property, Steven.
Thanks.
