I have had the same problem using 386 unix but not the same response 
from microport they were verry helpfull and I have had little if any
problem getting support.

	1 drstat in the error line will tell you which drive has the 
	  problem: 
	       	  if the hex byte is AX then it is drive 0 
		  if the hex byte is BX then it is drive 1
		  yes X is not a hex char but use your head
		  and substitute any value for X

  	2 I do understand that in the release comming out soon
	  they will fix some of the disk error problems
	  can't say which ones but I'm sure you will be pleased
