In tweeking my computer settings recently, I ticked off the DMA option in the IDE driver in WIN 98 SE Device Manager. My HD was a Seagate 4.2 Meg UDMA 33. When the system rebooted I got all sorts of errors and it insisted on running scan disk and I got the message "Boot sector record does not agree with backup, do you want to overwrite boot record 1 with the backup" If I answered no, it would repeat the process until I finially answered yes and then, when it rebooted, it couldn't find any windows system files. Booting up in Dos with a floppy and looking at the HD directory, all the folders were empty and ultimately I had to reformat the HD and re-install all my software. Surprisingly the HD now runs much better than before.
Can anyone explain exactly what happened. I won't try it again with this HD but am curious to know when this option can be used correctly?
