Amiga 1200 External drives question

[trackah123]

hello, i have a question.

i have 2 external amiga drives. they work on my a500 but they dont work on my a1200. so the external drives are working properly.

on the a500 when i insert a floppydisk in the external drive they just load up as it should be loading up.. but on the a1200 i can hear the external drives clicking (sector 0-1) but when i insert a floppy nothing happens. is this a a1200 hardware fault? or a jumper setting i need to change or something else? :-?

i recently installed a new a1200 internal disk drive and 40gb 2.5'' drive from amigakit.com in it. the internal drive and harddisk works fine.

i got a normal commodore a1200 no escom/tech or anything else.

hmm that would be weird because i got a brand new a1200 psu from amigakit.com

tried my a500 psu, didnt work either.. while on my a500 it does work.. so its not the psu.. tried 2 psu's

could be motherboard revision tho.. or maybe floppychip/port damaged? dunno  :-?

i have a new harddrive installed.. is it neccesary to set some jumpers in order for external floppydrives to work? or some wiring? something else?  :roll:
