Is the HDD actually a SCSI drive or is it IDE.
I believe the IDE drives still use scsi.device for a driver.
If it's IDE it should be attached to the A4000 IDE controller.
If it's SCSI, it would likely be connected to an expansion card SCSI controller. If that's the case you will need to identify the card and the name of its driver scsi.device.
If for instance I want to format the scsi drive on my A1200, on which I have both an IDE and SCSI drive attached, I have to change the tooltypes in the HDTOOLBOX icon so it finds the right driver, in my case 1230scsi.device. If I wish to format the IDE drive I would have to change it to just scsi.device.
You will also have to make sure that the scsi devices ID's are set appropriately and that the device at the end of the SCSI chain is terminated. Most SCSI drives CDROM's or HDD's that I have seen, have a Jumper to enable/disable termination, they also have Jumpers to set the SCSI ID's.
Most SCSI controllers that I have used generally use SCSI ID 0 as the controllers ID on the chain. All other SCSI devices on the chain must have a different ID set.
That said, SCSI controllers do not always use 0 as thier SCSI ID, so you'll have to figure that out by testing.
If it's SCSI 2 you have ID 0 to 7 available.
If ID 0 is used for the controller, you'll have 1-7 still available. In which case, you should be able to set any ID from 1-7 on you HDD.
Hope that helps :-D
