I have 3 internal hard disks, of which 1 for documents, which today tells me that most folders are empty (in Ubuntu 10.10).
I booted into another OS (Crunchbang Statler Debian) and saw that there the whole disk was empty.
Then booted into my 3rd OS (Fedora 14) and saw all my files were there.
Going back to Ubuntu I went to terminal and typed the suggestion that was given upon trying the disk again: dmesg | tail
dmesg | tail

Is the disk broken and for the wastebin? (I luckily have most files backed up)
Is it repairable in an easy enough way? (I'm no Linux guru at all)
Could it be caused by a hacker?
Strangest thing is that after a reboot all files seem to be there again (but for how long, I wonder)
