format command

I would like to make a partition read-only mountable on a IBM Microdrive (CMD646 controller).

I run the format command, then partition and use the attributes "rm" for the partition 0.

Still I can copy a file to the partition. What am I doing wrong?

The system is a Solaris 8 machine.

Unfortunately, the tag information in the VTOC isn't used by the mount command (at least to the extent that you would expect)Unmountable and read-only are ignored.--A.

Why don't you mount the partition 'read only' at boot time? e.g. In the '/etc/vfstab' have something like..../dev/dsk/c0t0d0s4 /dev/rdsk/c0t0d0s4/usrufs1noro.... ro = read onlyfdpx
