Thanks to your help, and that of Eduardo M KALINOWSKI, I have managed to get
rid of the sticky bit, by running successively:
# ls -l /dev/sdi
brw-rw---T 1 root floppy 8, 128 Dec 21 10:44 /dev/sdi
# chmod a+x /dev/sdi
# ls -l /dev/sdi
brwxrwx--t 1 root floppy 8, 128 Dec 21 10:44 /dev/sdi
# chmod a+rw /dev/sdi
# ls -l /dev/sdi
brwxrwxrwt 1 root floppy 8, 128 Dec 21 10:44 /dev/sdi
# chmod o-t /dev/sdi
# ls -l /dev/sdi
brwxrwxrwx 1 root floppy 8, 128 Dec 21 10:44 /dev/sdi
As you can see above, you need first a chhmod a+rw that converts the T in t,
after which a chmod o-t removes the t; chmod o-T does not work. Maybe there is
a simpler way, but this one did work.
Only fly in the ointment is that gparted still complains that:
Unable to open /dev/sdi read-write (Read-only file system). /dev/sdi has been
opened read-only.
Cheers,
Ron.
