Get Partition Magic and have a small partition for Win2k, and the rest of the drive for all your stuff. That way all your saved stuff will still be there. You will, however, have to install all the programs again after a reinstall of Windows. You should really consider something like a CD-Burner for backups to CD-RW too. That way if both drives manage to go you're not screwed over. You can get an 80GB Maxtor 5400rpm hard drive for around $300 USD. If you dont want to have to reinstall after a nice foul up of your system, so you're back where you were in a few minutes, you probably should consider RAID as alternative. Im not really too familiar with RAID, but if you dont want to reinstall all your programs, thats the best solution I can put up. Other wise you will end up reinstalling over your programs with the multiple partition method. If you dont want RAID, there is Norton Ghost, but Im not sure how well that does things, since some of the Norton line of programs excel in screwing up your registry, among other things.
