I've got a BASF 6185 ST412-interface drive which is spinning up, zeroing the
heads, and then giving three short pulses on the LED followed by one long one.
Anyone have a reference handy to tell me what that particular error code
means? I suspect it's the same on various BASF ST412 drives, so a manual from
one of their other models might give the answer too. I'm kicking myself as I
found these once a few years ago online and now they seem to have vanished.
I had the drive working - briefly - this morning, although it was throwing up
too many data errors to actually boot the OS [1] that was on it. Now it's just
giving the LED fault code above and not returning anything though, so I
suspect something terminal has happened. (And the exact meaning of the fault
is probably academic)
[1] It's the only copy of Torch UNIX for BBC micros (using a Torch 68000
co-processor) that I'm aware of, and a viable set of install media doesn't
seem to exist, unfortunately.
cheers

I've found the error code descriptions in the BASF 6188 manual (online
e.g. on pc-disk.de):
Fault-Codes
-----------
The Select-LED is used to flash error-messages in case certain fault
conditions should arise. For FAULT code displacement the red colored
front panel LED will be lighted. The information is presented in a
sequence by switching the select LED off. This means that the dark
Phases of the LED are counted to get the error code according to the
following table.
ERROR-CODES
-----------
1 DC ERROR
2 Motor Speed outside - 10% and Motor stop
3 STEP received while WRITE GATE is active
4 Motor Speed outside 1%
5 REZERO fails after POWER ON
6 Motor does not rotate inspite of MOTOR ON active
7 WRITE FAULT
Note
In case the unit was not selected by the Controller when an error
occurs (Select LED off) the LED will first be switched on and then
the above explained sequence takes place.
You've said that you have three short pulses followed by one long pulse:
------_-_-_-_-------_-_-_-_-----
In your case this would be error code 4.

Hmm, thanks for that - assuming the error codes are the same for my model of
drive, there's at least some chance the data can be salvaged.
I wonder if there's too much drag on the spindle bearings - when I first took
a look at the drive it needed a little encouragement to spin up at all. (But
I'm surprised the motor drive circuits don't just increase speed to compensate
- unless they're already driving things as fast as they can)
I haven't run the drive much - I'm tempted to leave it to warm up for 30
minutes or so and see if that makes any difference.
cheers,
Jules
