[wplug] help interperting errors in messages log

[Mike Griffin]

CRC errors indicate bad blocks on the HDD. If you're trying to use a  
CDROM and get CRC errors, the CDROM cannot be mounted. It's considered  
"bad media"  I might be wrong with this, but unless a block is marked  
"bad" the OS still tries to read from, and write to, these blocks  
creating the error when the attempt is unsuccessful.
