Cable?  Either a better cable, or improve its routing, or just crumple 
it so it can't cozy up to anything else, or simply unplug and replug 
it?  Also, what's on the power connector?  Unplug and replug that one 
too.

Replacing the drive can be done by adding a new drive to the Volume 
Group and using pvmove (not that I've done it).
