What i want to know is this, is it ok to let a hard drive set as a slave, to boot up? I havent had any problems so far, but wasnt sure if this was a good configuration. Also, does anyone have any other simple soloutions to running your pc as two computers, by using two hard drives? Basically I want to have 2 copmputers rolled into one, simply by having using two seperate hard drives. Being a media student and knowing that i would be working with large graphics and video i boought a 120gig Maxtor, when i first built my pc. This soon started filling up with work, aswell as music and games. So i bought a 200gig Maxtor. My original plan was to use this drive as the primary slave, but thought it was to good for that, since it had the 8mb cache and all. So i set it as the primary master and installed xp pro on that. I decided to use the new 200gig Mator for work, while using the 120gig Maxtor for music and games. When i wanted to work i would plug the 200gig in, and when i wanted to play games, i would unplug the 200gig, and let the 120gig boot up. I got fed up of removing cables, so i got a hard drive caddy and put the 200gig in to it, to do the same thing, but in a much easier way. The 200gig is set to master and 120gig set to slave (by adjusting the jumper on the drive). The 120gig uses the middle connector on the ide cable, and the 200gig uses the end connector, when its plugged in and being used. Thanks (sorry for the long post)

What I do instead of plugging and unplugging cable is to use the Bios for switching. You can usually enter the bios and tell it to boot from the second drive. The bios then changes the second drive to C: and boots from it. The first drive is changed to D:.

Should have learned about multibooting before spending all that time and hassle. You could do a reinstall of the OS with the best drive as primary. You would need to reinstall your games and such but you would have access to both drives at the same time.
