I just wanted to let you guys know that I got my 320GB Seagate HDDs and everything went smoothly. Since I didn't care about the data I just used the admin page to format and re-mirror the drives. Everything seems to be working and now all I need to do is wait for the drives to rebuild. I'm sure it'll take a little while since they are sort of large. So, thanks for all the help! I'm glad I have another NAS box, the more redundancy the better!
