[Cooker] Possible HD problems...

[Digital Wokan]

I think my Cooker install is crashing on me due to bad sectors on my
drive, but I have no idea how to find out if my drive has been going
bad.  Under Windows I had utilities to show me bad blocks.  I'm about to
retry the Cooker install and have it check for bad blocks during the
format.  How do I find out afterward if it found any?
