I run daemon tools on all my servers (with no problems), and this is
supposedly a driver that emulates scsi-drives. At least it shows up in
the scsi-drives portion in device manager.

All my ata-drives are also smaller than 200MB, except for a single 300MB
maxtor in a stand-alone fileserver. And none of the servers's a dell,
only OEMs or Compaq Proliant ML towermodels.
