It *could* be the device-select position. According to a chap I was
speaking to (WRT 8050 drives), there's an IC which determines which device
number the drive takes, and to change it one cuts tracks (or, if sensible,
pops the IC from its socket and bends the appropriate legs up before
re-inserting).

So it *may* be nothing more than that.

OTOH, that's the limit of my knowledge of these devices.


Cheers!
