It sounds more like the floppy cable is plugged in wrong on the drive..
Checking this on a 4000 is a bugger, cos you gotta disassemble the front of the case, unscrew the drive bays and pull it out..
I recently took mine apart to clean all the dust out of it as it was getting loads of disk errors. I put the cable back in 1 pin out of place, and it took ages to boot and the floppy light stayed on!
BTW, Buster 9 isn`t that bad.. AFAIK v11 is only needed if you use Z3 DMA type cards (fastlane scsi etc). ZII should be fine.
