Thanks for the reply Marcelo,

Does this mean that there is a physical or mechanical problem with the drive
itself? I do use 
reiserfs as it's the best fs available for my purposes. Could the drive
attempt to write 
outside its physical bounds? Move the arm right when it was instructed to go
left? I don't 
understand how the drive could have an error w/o affecting the filesystem.
