Folks have been talking about formatting on an RQDX1. The RQDX1 uses a
different format than that used by the RQDX2 and the VS2000. You can't
format a disk on an RQDX1 and use it in an RQDX2.
Did you mean RQDX3 (instead of RQDX2)?
After reading the documentation (RT-11 V5.04 release notes), the Pro is
capable of formatting the hard disk itself. RT11 even includes a program
for that purpose. It can only format standard drive types of course.
DW.SYS (Pro hard disk for RT-11) includes geometries for RD50, RD51,
RD52C, RD52Q, RD52A, RD53 and RD31. The handler identifies the drive by
determining the number of heads and then when there is a conflict the
number of cylinders. The hardware only supports 8 heads (3 select
lines). The driver does not support partitions so there is a maximum of
65535 blocks no matter how big the disk.
So, it looks like it would be much easier to get a non-standard drive to
work with a Pro than with an RQDX3 for example.
