I have inherited a Micropolis 1578 drive from a PC user who no longer
wants it, and I am trying to get it working on a Sun system.  The drive
had been connected to a Future Domain TMC-870 SCSI controller and was
operational.  I connected the drive to a Sun 3/60 using a power supply and
adapter cable stolen from a Sun shoebox.  The documentation that I have
for the drive is for installation in a PC and is minimal.  Format(8) sees
the drive and I can get the defect list and label it.  However, when
trying to format the drive, I get the following messages (repeated
endlessly) a few minutes after beginning the format:

si0:  siintr: bus error during dma
	last phase= 0x4 (DATA IN)
	csr= 0xa507  bcr= 27646  tcr= 0x4
	cbsr= 0x45 (DATA IN)  cdr= 0xc6 mr= 0x2  bsr= 0x81
	target= 0, lun= 0    DMA addr= 0x250c  count= 64512 (64512)
	cdb=    8  0  0  0  7e  0

Specifics:
	Micropolis 1578, P/N DS0006-05-6A
	Sun 3/60 Mono, 12 MB, SunOS 4.0.3

I am using the Sun standard format.dat entry for the 1578-15 and the
parameters seem to match the drive specs.  If you know how to configure
this drive for Sun, or are aware of any problems with using a drive that
was originally intended for use in a PC, I would appreciate hearing from
you.  Thanks.
