I assume you're talking about an RD53 or RD54 on an RQDX3 controller. These can often be helped by a reformat (which also maps out bad areas). If you have any VAXstation 2000s handy, the disk can be plugged into that machine and formatted; otherwise you would need DEC's diagnostics. The RQDX2 controller uses different formatting. The RD53 is a Micropolis 1325 or 1335 with a jumper shorting R7 on the PC board. The RD54 is an unmodified Maxtor XT-2190. I'm not sure how you'd format these if you buy from a non-DEC oriented supplier. Chris
