ATA pass-through is broken in 2000 and XP up through SP1. For this to work
properly you must upgrade to XP SP2 or use Server 2003 and use
IOCTL_ATA_PASS_THROUGH or IOCTL_ATA_PASS_THROUGH_DIRECT. You will also need
to compile your application with a path to the latest DDK for Server 2003 to
provide the proper definitions for the ATA_PASS_THROUGH/DIRECT structures.
Caveats to be aware of: DMA does not work with pass through so you are
limited to PIO.
Microsoft does have a hot fix avaialable for XP SP1 which replaces
atapi.sys. That might still be supported. As to a fix for 2000, that is
supposed to be in the next SP(5).
