I'm relearning RT-11 on an 11/23 I was kindly given (thanks David!).
I'm having trouble with the RX02 drives. I can boot RT11, and .format DY1:
About 1/3rd of the time I get an error while formatting, this is on
known good 8" SS/DD media that has been extensively tested on a CP/M
system in both SD and DD modes.
On media which does format fine, I get gobs of bad blocks using
.initialize/badblocks DY1:
The only media that seems to work fine is "real" RX02 media.
Is the RX02 incapable of formatting it's own media? Is there a common
hardware problem that I should look for? Filter caps? Clean the
stepper motor?
Many thanks.
