If its just the Harddrive that has failed why not just replace the drive in the external unit.
DataFlyer 1000 SCSI:
AMD 5380 SCSI controller
50 pin internal SCSI header
optional external DB25 connector
DataFlyer 1000 IDE:
40 pin internal IDE header
hard disk activity LED on front of the case
What drive type is in your unit (IDE/SCSI) suspect once the drive has been replaced you should be able to prep with the setup software as before.But you need to confirm that it is the drive and not the Data flyer controller that is faulty.
