Can you get your installed package list from rpm and tell yum to 
reinstall them?  Overkill perhaps, but I've always thought there should 
a handy(ier) way to get the list from one box and duplicate that set on 
another which would mostly be the same operation.

'smartctl' will give you a health overview.  If the drive is too old to 
have the smart interface, it's probably time to replace it.
