Hardware Issues
If you ever decide that you need an IDE hardware RAID, be wary of Western Digital drives. One of our computers here has a 3Ware Hardware RAID controller with WD disks, and apparently the Western Digital drives go to sleep when they are not being used which essentially is causing the RAID controller to think that they are dead, or missing and it tries to restore it, and sometimes a couple of disks might sleep which could cause the controller to freak out and molest your data. Apparently there is a fix for it, but if you only learn of this problem the hard way that is only a small consolation. Be ye warned.
