If you make the media read-only at the hardware level, by all means mount it read-only. If you're just asking why this interesting phenomenon occurs, that's a different question. I'm not sure if it's an MS-DOS filesystem, but a UFS mount will want to modify the superblock with the mount time and mount point. Mostly, I suspect, so that fsck can display that information. :-) -crl -- Chad R.
