How are you supposed to fix a broken computer, unless you can look up online how to fix it with another? (You may need more if you're doing stuff like testing networking).
My computer has two hard drives, with an OS partition with full software installation on each. I have spliced into the ribbon cable and installed a DPST switch between the power supply and the second hard drive so that I can normally run with the second hard drive off, but if something goes wrong with the OS on the first hard drive, I can pull all my documents onto the second hard drive, nuke the OS on the first hard drive, restore the OS on the first hard drive from a Norton Ghost image, put the documents back, and revert to normal operation. I usually have to do this once a year or so when a file gets corrupted or I get malware or such. Recently I had to do this when a file got corrupted while I was on this site. In that way, I can fix anything that goes wrong with only one computer, but two hard drives. This also provides easy means of backing up the documents too. The ribbon cable splice has a switch in the master wire that lets me choose which drive to set as master without having to go in and move the cable.
Normal operation: Drive 1 set as master and drive 1 on, drive 2 off.
Nuke it: Drives 1 and 2 on, drive 2 set as master. Move documents from drive 1 to drive 2, then use OS on drive 2 to nuke OS on drive 1. Restore drive 1 OS from ghost image.
Backups during normal operation: Drive 1 set as master with drives 1 and 2 on, copy documents from drive 1 to drive 2.
All changes to choice of master and drive 2 on/off are made with the power off!
