-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I use the following sequence to burn dvds, in a script: time growisofs -Z /dev/dvd=IMAGEFILE -dvd-compat -speed=8 sleep 5 echo Ejecting eject /dev/dvd sleep 5 ls -l /dev/hdc file -s /dev/hdc sleep 1 file -s /dev/hdc echo Comparing... time nice cmp --bytes=$(wc -c <IMAGEFILE) /dev/hdc IMAGEFILE date And some times, not always, I see this output (the marked line): [...] Ejecting brw-rw----+ 1 root disk 22, 0 2009-03-13 03:55 /dev/hdc couldn't open file /dev/hdc: writable, no read permission <======== THIS == /dev/hdc: LUKS encrypted file, ver 1 [aes, cbc-essiv:sha256, sha1] UUID: d6367de2-9ecd-4e74-85d3-6acc8e6 Comparing... I explain. First, I burn the image. Then, I eject the dvd, to force the kernel to reread it (k3b does the same). Then, I compare the image with the just burned dvd, but in order to avoid the random error, I first run "file -s /dev/dvd", which makes the burner to close the door. The curious thing is that, on some runs, the first attempt to read the dvd fails with the message: /dev/hdc: writable, no read permission which is not true, because the permissions, read just before, are: brw-rw----+ 1 root disk 22, 0 2009-03-13 03:55 /dev/hdc and the second attempt succeeds. That's why I run the "file" command before the "cmp", so that the cmp succeeds (ie, previously I got the same error on the cmp). And it doesn't happen every day, just some times. If it happened every time, I'd think it could be the door closing and the system attempting to load the dvd. And it did not happen several months ago, with 10.3. Curious, isn't it? (running 11.0; gnome; stock install plus mandatory and recommended updates) - -- Cheers, Carlos E.
