OK so I got my 74gb WD Raptor yesterday. Popped it in, put in my XP Pro install disc (after partitioning and doing a full format on the drive), started installing windows..... Everything was going fine, and after the "Copying Files" step, it rebooted, and said "Error loading operating system". I tried 2 different XP Pro install discs and got the same crap...I went through this about 8 times. After the first time it didn't work, I removed my Seagate (current hard drive). So then for some reason my old hard drive wouldn't boot up after I put it back in...so I used an XP Pro upgrade cd and reinstalled windows and here I am. SO now I can either send the Raptor back and get a refund towards an MP3 player (which I'm leaning towards doing), or if maybe someone has a remedy for this I can proceed with it. I'm trying to install Windows and all my other progams that I use on the Raptor, and have all the other crap (Porn/movies/songs) on my Seagate.
