Thanks all!



I found a Seagate 80 gig hard drive (not the same model as what was in 
the 550 - too lazy to run downstairs and get real model numbers) I 
pulled (what I think is the bad drive) installed the new drive, fired it 
up and it's re-syncing!

As soon as it's done I am going to hunt for another drive to replace the 
other "original drive" per Stephanie's  recommendation

Yes both drives have been running flawlessly since 2003.

Since the box has raid on it I use it here at home as a backup for my 
backups.


Thanks again all!
