FD400 drive troubleshooting

[Richard A. Cini]

The "he" is me...

I've swapped drives originally and this drive worked for a short time. I was
originally looking for common failure modes for these drives. I've cleaned
the heads using a disk but a more thorough and direct cleaning is warranted.
The problem is that this is the second drive in the pair and to get to it
means I have to disassemble half of the unit. I just haven't had the time in
the last few days. 

I also want to check the drive RPM. I found a program for the Model 100 and
bar code reader which turns it into a stroboscope, but I wanted to validate
it on a working drive, so I have to pull out a TM100 drive. But, alas, I
haven't had time for that in the last few days, either. I'm going to try to
do that today.
