I have a KT7 that FreeBSD 4.2-Stable doesn't like combination of Via and Maxtor's. The various incantations of Windows didn't have any problems with the drive (s), i.e., no messages in the event-viewer files. Using a Promise card for the hook up works just fine with FreeBSD 4.2-stable and Windows. You can also set Maxtor drives to run any mode you want. They come out of the box UDMA-5, which is UDMA-100, but Maxtor's udmaupt utility will program the drive to any mode you want. It is one of their utility programs that is listed for the purpose of upgrading some ATA-66 drives to run ATA-100 mode. Maxtor has a utility call MaxDiag or something close that you can use to check it. It doesn't even have to be added into your bios to do this. There are some systems out there that totally freak out when you use Dangerously Dedicated and the only way to recover your system was to low-level format the drive while it isn't mounted. I think MaxBlast may cover that now by writing an MBR the system can deal with. I got burned using DD and haven't tried it since.
