Have the connections ie the pins outs for floppy drives or even the cables changed recently?
I've not used or even connected a floppy drive in ages but recently needed to so that I could do a BIOS update but no matter what I did either the drive wasn't detected or when the cable is plugged in the wrong way the light would stay lit. Tried different drives, different cables but nothing would get the sucker working. Tried the drive in a different mobo and same results but in a third comp the drive works fine.
The boards the drive won't work in are an Asus P4P800E Dlx and a Gigabyte DS3P, tried the drive in a Fujitsu 915 mobo and the thing chugs along quite happily.
Any ideas or am I just getting too old for the comp scene
