:-) The brushes themselves are indeed removed from the arms,
but I left the motor/arms assembly to keep the original state.
Exactly what it should be doing.
Thanks! Good to hear.
Are you sure about that? You can't recover a
bulk-erased pack
because you can't rebuild the servo surface, but this drive
has a separate servo surface so there's no good reason why
you couldn't reformat the data surfaces.
I've not tried it, though.
True, just like the RL01/RL02 there is a separate servo track
on the platters of the RK06/RK07. Indeed, I did try the .FORMAT
command, but RT11 reported that the command was not available
for the device, or something like that.
".INIT" gave me an error like the ".DIR" command.
You are correct that you can format the RK07! It does not write
the servo tracks ("impossible"), but it does write the data *and*
the headers. However, that format command is not in RT11, but it
is in XXDP.
Edward tried his RK07 last evening, and after he loaded a pack
(no controller connected at all), he saw the same events (LEDs
and head movement), but on his drive the READY lamp illuminated.
I have the field maintenance print set ...
It's been several years since I fiddled with one
of thsese
(too many machines, too little time...) but something in the
back of my mind says that one of the lamps comes on when the
controller accesses the drive for the first time. It may just
be the lamp in the 'A' button.
Correct. As Edward saw, the READY lamp must go ON when the heads
are on track 0. I have read in the RK611 controller manual (damn,
I can't find that one now!) that the "A" or "B" indicator is lit
when the controller attached to the channel does an access.
Time to test the drive without any cabling (to copy the exact
condition that Edward has), and check the cables to the controller.
Then try to run some of the RK611/RK07 XXDP programs!
Perhaps they can tell something before I grab the DVM and scope ...
thanks,
