Has anyone got a teledisk image of the fluke 9100 service disk? Or any other way of testing and formatting a 9100a hard disc? My NOS 9100a is failing to boot from the HDD (first time ever!), when it boots from floppies and I attempt to copy files from the system floppies to the HDD results in error : I/O Module fuse blown! This seems unlikely since there is no IO module or anything else for that matter plugged in. I swapped in the noisey HDD from my other system and the machine boots just fine. I tried swapping the MFM-SCSI adaptor card but that made no difference so it's either a drive fault or it needs a reformat.
