Frank if WP LED is on then it will not format the disk. Check disk drive connections/jumpers etc. If 8” disk, WP notch on disk must be covered (unlike 5” disks).

I have a problem with the ZFDC controller to format a disk. My system contains the following boards at this stage: * Z80 Master CPU with Z80 Monitor * 1MB S.C. Digital 256KM Memory board * CompuPro Interfacer1 board * Dual IDE board with the banked CPM3 Prop Image * SMB board * ZFDC board with an Tandon TM848E2 connected I am able to do all R/W tests with a IBM3740 formatted disk with success. When i try to format the disk as a IBM3740 disk the controller stays locked with the HALT LED & the WP LED on, until i reset the system. I have no clue, which problem the controller have at these moment. Frank -- You received this message because you are subscribed to the Google Groups "N8VEM-S100" group.
