burner hangs after blanking with growisofs
Due to an interest in blanking some backup media to clear out sensitive data, I elected to blank DVD+RW using the following:
growisofs -Z /dev/sr0=/dev/zero
Sometimes, the burner appears to be hung midpoint in the process, resulting in the need for a reboot. Years ago, when extensively playing with growisofs, I am sure that I blanked media several times. (Normally it is not required, or desired.)
On the last instance, the blanking failed at the 41% point, and I got errors that growisofs could not flush cache.
I have tried this several times, without KDE running, and cannot duplicate it. It can run for a while until it fails.
Any pointers on how I can better analyze what's going on, so that I can fix this unfortunate annoyance? My Slackware systems go months without rebooting, and a silly DVD burner shouldn't be causing this kind of headache.
