So any of a number of mechanisms could be handling this, and IIRC at least some of them may not actually present the drive as mounted at all (I believe I'm thinking of gvfs, there) - in which case the latter of the above commands may not present any useful information. >> What do the logs say? /var/log/syslog, or .../messages? > > I fail to open it Try doing it as root. You might also try running the command 'dmesg', also as root; that's likely to present a lot more information, although if you do it right after the change to read-only has happened then the relevant part (if any) is likely to be in the final few lines. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
