Fdisk under >DOS can't do this so you can change it under MINIX or compile the MINIX fdisk No. I use DrDos 5.0 and have a second drive with the partition table created by MINIX and marked as MINIX (1.5.10) and DOS _still_ recognised the drive. After a dd command (in MINIX) as above it could no longer *see* the drive. But be sure to use a file > 512 bytes (I used a command from /bin) or dd will end with 0+1 blocks and thus will have written NOTHING. -- Wayne Hodgen | hodgen@infko.UUCP | All Opinions (c) Me 1991 Uni Koblenz, | (..!unido!infko!hodgen) | Stuff your "reality", Rheinau 3-4, | Voice: +49 261 9119-418 | all *I* need is Hack!!! 5400 Koblenz, Germany | Fax: +49 261 37524 | "Dark Lurker" strikes again.
