Allow for easier use of files - Just define what you know.

HD == hard drive - min file name req.
* Defaults to SCSI ID 0, LUN 0, 512 block size.
HD1 == SCSI ID 1, LUN 0, 512
HD11 == SCSI ID 1, LUN 1, 512
HD11_1024 == SCSI ID 1, LUN 1, 1024
HD System 7.0.1 Apps.dsk == ID 0, LUN 0, 512
* suffix no longer required
