elSmoko, if you run Win2K then the 75GXP won't be detected properly. I couldn't get the drive out of PIO mode and finally must run it on the HPT Raid as single drive. It's a combination of Win2K and Via Busmaster drivers not able to handle ATA100 drives. I heard some beta Via 4-in-1 drivers may alleviate the problem somewhat. I do not install 4-in-1 after I read about the problems people are having with it.
