8" floppy formatting

I need to reformat a bunch of old 8" floppy disks for use on a Terak system with single sided single density shugart drives. Terak's cannot format floppies (well, actually I recall a program that could format, but it required special hardware and DSDD drives on the Terak, which I dont have). I will attempt to format the floppies on a Cromemco Z-2 system with DSDD drives. Assuming this even works, I'm wondering if I should buy a tape eraser and use it on the floppies before attempting to reformat them. I need the 'standard' SSSD format, which I think is 26 sectors, 128 bytes/sector. Any suggestions on the best way to proceed will be appreciated. I need to backup the old floppy disk software I have before time or accidents cause me to lose some of it forever. -Lawrence LeMay lemay(a)cs.umn.edu PS: I'm looking into obtaining permission to distribute the software and manuals and operating system that were developed here at the University of Minnesota, Minneapolis.
