but you HAVE to change the drive address from drive 1 to drive 0. That's easier on some PC drives than others. In all, PC drives are much easier to use with the ST than the Amiga.
The setting of the drive adress jumper depends on what you are doing.
- 520/1040STf(m), Mega ST, Mega STE, TT, STacy, Falcon internal drive, SF314, SF 354, only one drive connected to originnal cable: set DS 0
- 520/1040STf(m), STE, Mega ST, Mega STE, TT, STacy internal drive, one or two drive connected to 1:1 unwrapped cable: set A. to DS 0, B: to DS 1
- 520/1040STf(m), STE, Mega ST, Mega STE, TT, STacy internal drive, one or two drive connected to pc style wrapped cable: set both to DS 1
- Atari PC 1-5 (maybe even ABC series?): should be PC style wrapped cable internally, but not sure. Some do support one external SF 314/354 drive.
(Note, that Falcon does not support 2nd drive without hardware hack, as it's floppy controller does not generate DS1 signal.)
(Note, that when daisychaing two SF 314/354 on 520ST, then it autmatically swaps DS1 to DS0 for the 2nd drive)
(Note, that 520/1040STf(m), STE, Mega ST, Mega STE, TT, STacy, Atari PC 1-5 do not support 2 external drives (like SF 314/354), only one )
(Note, that 260ST, 520ST, 520ST+ do support two external drives (as they don't have internal)
