The message you got means that you have a disk problem.  It may be a bad
spot on the disk.  If that is the case, you can use prep -a to get rid
of that bad block.  (find out what you are getting rid of first, so you
can restore it later).  If it is more than a bad block , you may need to re-
initialize the disk, and start over.  In a worse case you may need to 
replace the entire drive.
