I just swapped out the two failing 80gb drives that were in this server for 2 brand new 160gb drives. It took about 3 hours to transfer the data and now everything appears to be up and running ok. The second drive will be a daily backup of the main drive. In the next few days I will also be upgrading the database server. Enjoy!
[It's a good thing the server is back up because while it was down, 44 spam emails were waiting for me!]
