one that's modded to spin at 300rpm. Same exact behavior on all three.

Can you describe the problem in detail? I recall that you're using a 16FDC
with 8" drives that are not Persci brand. Are you aware that the 16FDC 8"
bus is wired differently than what is required for Shugart compatible
drives? The Persci drives did not have a TG43 signal so the write current
may be too high on the inner tracks of a non-Persci drive mated to a 16FDC
-- causing errors.
That's good to know for when I do attempt to hook up an 8" drive -- thanks!

Fortunately, it is possible to modify a 16FDC to be compatible with a
couple of cuts and jumpers. I have some photos and text that describe the
mod.
Should this happen to be the problem you're experiencing, I'll upload the
mod info to a site and send the link. If not, please describe what problem
you are having in more detail.
