Just a warning:

Write protection is REPORTED by the drive, NOT ENFORCED by it.  the
trackdisk.device does enforce it, though, and I doubt there's enough
space in the boot block for low-level disk I/O routines.  So, write-
protected disks are PROBABLY safe.  It would be nice if someone
verified this, though.
