When I mount a DVD on this wheezy desktop, I get: $ mount /media/cdrom0 mount: block device /dev/sr0 is write-protected, mounting read-only mount: /dev/sr0 already mounted or /media/cdrom0 busy $ mount /media/cdrom0 mount: block device /dev/sr0 is write-protected, mounting read-only $
It doesn't matter how long I wait after inserting the DVD. It seems to happen whenever I insert a disk. Otherwise, everything is normal. Unmounting and mounting again (without ejecting in between) is normal. /etc/fstab includes the line: /dev/sr0 /media/cdrom0 udf,iso9660 user,noauto I can live with this, but I'm curious to know why.
