I copied Teledisk in the C: eledisk directory. But I tried this to test if it works, unfortunately I don't know if this bug related In also configure The floppy drive as 720kb in both 86box configuration and the setup bios.Ĩ6box read the TD0 image file as a floppy disk correctly. I also get an error when start to write the 720kb blank floppy image. Today I tested Teledisk to convert a TD0 file to the emulated 720kb floppy disks. I also have another VM with a 386 and DOS 6.0 and has the same issue. (Can format a 5.25 360kb floppy disk on a 5.25 1.2MB drive, altought I did not test, if it happens on the 5.25 disk format).ĭesktop (please complete the following information): DOS 3.2 added support for 720kb floppy disks and added disk format autodetection. It should detect the disk format correctly.

Type FORMAT A: (If the disk drive is A).On DOS 4.0 and later is possible to force a 720kb format using the FORMAT command with the /F:720 parameter.It formats correctly a 720kb disk on 720kb drive. This bug only occurs when 1.44MB floppy is used.This affects all DOS versions from 3.30 (this was the first version with 1.44MB floppy disk support) to MS-DOS 6.22. The DOS FORMAT utility, throws an error when formatting a 3.5 720KB floppy on a 1.44MB disk drive.
