It could be a hard disk, but it could be other things too.

If the hardware hasn't been touched since the last time it worked,
then a failing disk would be a pretty safe guess.  If not, or
especially if this is a new configuration, there are a few things to
try first.  One is to make sure that there is a master on the ATA bus
containing ad5; the ATA specs say that you're not supposed to have a
slave unless there's a master (the quickest way to fix it would be to
move the disk from slave to master).  

And of course, cable problems are a *very* frequent issue.
