If
this is your board, the page doesn't show that it supports RAID.
Another approach to the security you want would be to buy a second hard drive about the same size as your current one, install it in a
mobile rack and use Norton Ghost or Acronis True Image to clone your drive. This may be better for several reasons:
1. The cloned drive is a full working copy of your current drive. If your main drive dies, transfer the clone drive to the main position, and keep stepping.
2. As long as you're careful to scan your drive for viruses, spyware, etc. before you Ghost it, you're always as good as your last Ghost. If your drive becomes infected or corrupted, just Ghost back from your last good backup. The most you'll lose is any new files, and maybe not that, as long as you can save the new files before restoring from your backup.
3. It takes only minutes to clone a large drive. It takes about ten minutes to clone my 80 GB ATA133 drive and less for my friends to clone their larger SATA drives. On most sysems, it takes longer to do "the three S's" in the morning than to clone your drive.
4. If you use a mobile rack, you can unplug the clone drive when you're done. If you get a viruses, it will be on your RAID partition(s). There is no virus that can jump the air gap. when your backup is unplugged.
5. A Ghost drive doesn't require special setup or formatting so you can read it on any other machine if you need to pull info from the drive.
6. Large drives are cheap. Add $15 - $25 for a mobile rack, and you've got a full backup system for very little money.
All it requires is one spare 5.25" bay for the rack, and you've got it.
Any version of Ghost from 2003 on supports USB and firewire so you could also use an external drive. If you do, I suggest buying a standard drive and a
separate external chassis with USB interface that supports the drive you buy (ATA, SATA, etc.). That way, you'll know the make and model of the actual drive and that it works well with your system. Typically, that also costs less than a pre-assembled external drive.
