By Just added a 3rd hard drive to my system.
It happens to be the smallest of the 3; at only 74gb. But it's a Western Digital Raptor 10000rpm SATA drive. Guy from work had bought it for his latest system build and ended up not using it. I wasn't originally going to bother but decided that I could use it as my new boot drive.
After cloning my C: partition over and ensuring it was stable I wiped the old C: partition off of the old ATA/100 drive and moved the D: partition up to take up all the space. I now have individual drives for my System (C:), Games (D:) and Storage (E:).
It's unreal how fast it is. Using the old C: drive I'd see the XP bar go across 8 or 9 times at least. Using the new drive it barely makes it over once before the XP login screen appears.
I don't think I like you any more. :D It wasn't from Alienware by any chance was it?
