The buffer on the CW is large enough to record much more than a
single revolution of a diskette, so when dealing with diskettes of
this type, I fill it up with larger sample. Decoding then proceeds
with the first good (complete) sector in the buffer. I don't even
bother to pay attention to the index pulse in this case--I just allow
a certain amount of settling time after seeking and begin recording
for a sufficiently long time to grab about a rev and a half.
It's really no problem at all.
