Is it possible to set up a single disk raid (kind of redundant to call a single disk an array) but I've got a single SATA drive in the machine not doing anything. It's a 10k maxtor 74G drive, and what I really want is just to backup two home partitions. I can always reinstall the OS, but the data can't be recovered that easily. The mobo supports raid-0,1 and jbod. Suggestions?

Don't think of it as RAID, think of it as backup. Do some scripting with rsync or use a package like amanda, and perform backups of your home partitions to the raptor drive.

Really for RAID, you want identical disks. Better solution would be to just archive important data to the drive on a semi-regular basis.
as for raid on just one disk, it's not a belt&suspenders type scenario, it's a "wearing two belts" scenario. There's no real point, because if the drive fails, you're screwed just the same.

This would be a good job for rsync perhaps....

You can set up raid1 on a single disk if the intent is to add another disk later on. When you add the second (or third) disk run mdadm and get the disk recognised in to the "array" Else as other have suggested rsync in cron will do an easier job of backing up on regular basis and will take less than a minute if run it regularly, say half hour.
