I forgot to mention that I got the LED error code table from a technical manual for later Miniscribe drives, so it's possible that the blink pattern means something different on the 3425. I think it's likely to be correct, though, given the way the stepper is behaving at power up. -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/
