So now that I've got the 8" drive running
well on the PC, I am trying to
read 8" CP/M disks. 22Disk is giving me sector not found errors
(cylinder 2, side 0, sector 1) and the DOS CP/M tools are giving me
"Unknown floppy disk format", even on disks that read fine on my NEC APC.
I tried reading in a sector using debug but I also get read errors.
Any ideas?
The drive is a Tandon TM 848-02. Very little information online, but it
seems to support DSDD.
1) What disk format is it?
2) If you can "ignore" the error on sector #1, can it read sector #2?
(WD formats sometimes start too soon after the index pulse for NEC)
3) "Sector Not Found" (err #4) is likely to be due to the "wrong"
format.
(wrong sector size or wrong sector number), but it IS MFM
4) err #2 (address mark) means wrong density/recording type/data transfer
rate
