Hard Drive Problems with A/UX 1.1

[Patrick Wall]

I am having a problem making a file system on my external hard drive. I
followed the directions given in the Installation Guide, but when I get to
the step that makes a file system, I get this error:
	Disk write c5d0s2  Error: More Data than SCSI device requested
	Logical block (block number), physical blocks (block number, block
	number).

After three such messages for the same block, I get this:
	Generic Disk c5d0s2 retry limit exceed : Logical block (block
	number), physical blocks (block number, block number)

I'm running A/UX 1.1 and trying to create the file system on a 50meg partition
on a Micropolis 158meg drive formatted with Silverlining.

Is the drive incompatible with the generic driver under A/UX? 
I have also tried with mkfs1b, but I still get errors although not as many.
	Thanks in advance,
