utility on the
XXDP disk. I took all of the defaults and got the
following failure. Does this indicate that my RQDX3 controller is
bad or is this likely to indicate a bad hard drive?
Since the controller handles the RX50 OK, almost all of it must be
working. If the LED on the RQDX3 goes out a few seconds after
resetting, with the RD54 disconnected, the RQDX3 has passed its
self-test. From the error, I'd say possibly the RD54 has never
been formatted on an RQDX3, or more likely something is wrong with
the jumpers or connections.
Double check that the drive select jumper is correct (normally it
should be DS3; does the drive's LED flash when you run ZRQC?), that
the little control board in the front of your BA23/BA123 with the
READY and WRT PROT buttons is properly connected and those switches
are set correctly, and that the cables from the distribution panel
are connected correctly (with both the RD54 cables connected to the
lower-numbered port). It's just possible you have too old a
version of the firmware on the RQDX3 (what are the EPROM numbers?)
or that its jumpers (eg W23) are set wrongly, but this is less
likely I think.
You were right about needing to switch drive select to 3. That made
it possible to format the RD54 drive. It formatted successfully with
40 bad LBNs and 7 retired. I also tried formatting my five RD53s and
one formatted successfully with 27 bad LBNs. The other four failed to
even be detected as far as I can tell. Is there any point in playing
with these or would I be better off just trashing them?
Also, how bad are 27-40 bad LBNs? I know that they can be mapped out
but is this a sign that the drive is dying?
Thanks,
David
