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.
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?
If you consider how many blocks in 159 MBytes, that
is VERY few! And the bad LBNs are mapped out during
the format. The software only sees a continuous map
even though the RDQX3 will substitute blocks from the
end (AFAIK) of the drive which does slow things down
just a bit, but not enough to be concerned.
Based on my understanding of how long an RD54 lasts,
I doubt that your RD54 is dying.
Sincerely yours,
Jerome Fine
