The problem is most likely to do with the fact that the Fujitsu is ATA66, and your motherboard doesn't have a clue how to deal with it.

You need to download a small DOS utility from Fujitsu's site that switches your 17GB drive to report itself to the motherboard as being ATA33, rather than ATA66. Once that's done, the DMA box should stay ticked.

You also need an 80-wire cable - otherwise, you'll end up getting errors that can result in your spending hours waiting for the drives to have surface scans carried out.

If for some reason you are running NT SP5 it seems that after checking DMA you need to rerun SP5. Microsoft appears to have designed the SP that anytime you do anything to the OS you need to rerun it.

A few mother boards Shuttle etc with Award bios seem to just have problems until you get everything just right.
