Bill -- the drive and disks are double-sided double density. Are you saying that's quad density?
I may try a different host setup again. I have five different computers that passed the testfdc program with varying levels of success, although none with single-density.

The computer thought it was writing to a 1.2M 5 1/4 disk. BUT you're saying a quad density SS disk. I never tried that and if you say it does not work then I can't dispute that without trying it myself.

I am aware of the track differences and I thought Dos would format it but just slam the head for the last three tracks. No such luck. It actually complains about the disk from the beginning. The Qume 242 is a DSDD drive in case that was asked in the original thread, and should work in this situation. I tried to format a disk with both IMD and NFORMAT (utility I downloaded) and neither products a disk format that DOS likes. I'm sure it's my selection of parameters more so than the program itself.

Go back and read what I wrote, Bill. If single-sided media is being used, DOS formatting will fail as there is no single-sided high-density format available. Of course, if double-sided media is used, DOS formatting as a 1.2MB DOS disk should work--up to track 76. Note that 8" drives are 77 track/cylinder, not 80, as the 5.25" drives are. IMD can handle the issues quite readily, as its formatting facility will do whatever you tell it to do. --Chuck
