Fine, but what does this have to do with the operation of the 3.0"
drives that Philip was asking about? AFAIK, the custom ICs used on
Teac drives are sui generis and not shared with other manufacturers.
It'd be a little difficult to generalize universal operation from
Teac specs, I'd think.
At any rate, on many Teac 3.5" drives, there are many undocumented
jumpers (look for the pads marked "Sx"), so behavior is a lot more
flexible than the OEM documentation would imply for that model.
For example, one can convert several models of the FD235HF to operate
as FD235HG by changing the setting of the pads at S4.
