Has anyone has success with FDD's beyond B: ?

Transcopy (TC.EXE V5.4) accepts FDD E: as a source/target, however it fails to read/write from/to it.

Silly question: How are you getting your additional drive letters (i.e. is it part of a 4-drive controller or is it via an added controller (i.e. not primary))? If it's the latter, remember that the OB uses the primary controller to perform some tasks such as seeking and drive select. Since the OB is only aware of the primary FDC, how would it know to use a secondary?

Yes, good points.

Obviously from my Tandy / RS thread, I'm now going to try a hack to disable the on-board Tandy 1000 FDC and try my CC1 or IV as the primary FDC.
