I got some kind of weird output from that: root # hdparm -z /dev/hdc /dev/hdc: re-reading partition table BLKRRPART failed: Invalid argument fdisk has no better luck: sudo fdisk /dev/hdc Password: Unable to open /dev/hdc I was able to freeup the tray though. It now works and will open and close by pushing the button. But a reboot did nothing toward establishing a device in /dev/ for it. Or I should say the link to CDrom. /dev/hdc seems to be there The rules you mentioned at: /etc/udev/rules.d/70-persistent-cd.rules (wrapped for mail) # LITE-ON_CD-ROM_LTN-5291S (pci-0000:00:1f.1) SUBSYSTEM=="block", ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:1f.1", SYMLINK+="cdrom", ENV{GENERATED}="1" That looks ok but I don't think I'd know if it were totally wrong either. I've renamed it and will reboot later on.
