Formatting disk on rt11

<> <How can I format a rd54 disk on a rt11 5.3 ? <> You cannot unless you write your own utility. < <Jerome Fine replies: < <For novice PDP-11 folk, this part is incorrect, as Allison <surely knows, but probably just answered too quickly. <Technically, I suppose Allison is correct, but I have <never heard of anyone writing their own version of ZRQC?? No, I am correct. there is no formatter for RDxx drives under RT-11. XXDP does it really well but that is NOT RT-ll. There is a lot of work but writing a utility to format a RD under RT-11 is possible, though if you have the tools and info to do that you also know XXDP is available. <Just a note of clarification (again, Allison this is not a flame that you u <but just correcting your "spelling" - anyone who knows realizes and anyone <who doesn't understand - it doesn't matter). Allison was referring to the <SET DUn: UNIT=u, PART=p Actually I've never used a RD larger than 31mb on an RT11 system so the SET DUn would not have come to mind. Why no big disks? I have MANY MANY RD52s and an RD53/54 would be VAX fodder. Also while RQDX3s are RD54 aware, some of the RQDX1 and 2s are very much unaware of the RD54 and will produce errors. Allison
