Perhaps there's no solution, other than rebooting or maybe getting a different DVD writer drive, but here's my problem. When using K3B to write to dvd+r and dvd+r dl media with Verify selected, after the write completes and the tray is ejected and reloaded, I see a "No tracks" message when the verify phase begins and the drive becomes inaccessible and unusable. Only a reboot restores the drive to usability. By unusable I mean: the green LED is on and steady, the drive isn't accessible from any software I've tried, it doesn't show up as busy via lsof, and the manual eject button does nothing. This lockup also happened recently, once, when trying to begin the write phase (with blank media). There was no indication of error from K3B, it just hung. After a reboot, a second try to copy the iso (w/K3B) to the same disk went w/o a hitch. This is an up-to-date F7 system. The drive is a Benq DW1655 with the last released firmware update. This problem never occurred under FC4 before I upgraded a while back, though then I tended to use GnomeBaker for writing iso's to disk. GnomeBaker never works since the upgrade to F7, though it fails w/o affecting the drive (or writing anything to the blank disk, for that matter). There is another optical drive, a Lite-On LTR-52327S, whose operation is unaffected when the Benq stops responding. Though I wouldn't mind a solution that prevents the drive lockup, what I'd be more interested in is a way to restore the operation of the drive w/o a reboot. Any ideas? Regards, Doug Wyatt
Sounds like my problem that turned out to be a failing power supply. The problem may only show up during the DVD/CD burn process. I had a drive replaced under warranty but the new drive still had an issue.
My 5V rail was dropping. Two power supplies from the same company that had the same 5V rail dropping issue.
