5 I got some kind of weird output from that:

7 root # hdparm -z /dev/hdc
8
9 /dev/hdc:
10 re-reading partition table
11 BLKRRPART failed: Invalid argument
12
13 fdisk has no better luck:
14 sudo fdisk /dev/hdc
15 Password:

17 Unable to open /dev/hdc

19 I was able to freeup the tray though. It now works and will open and
20 close by pushing the button.

22 But a reboot did nothing toward establishing a device in /dev/ for it.
23 Or I should say the link to CDrom. /dev/hdc seems to be there

25 The rules you mentioned at:
26 /etc/udev/rules.d/70-persistent-cd.rules

29 # LITE-ON_CD-ROM_LTN-5291S (pci-0000:00:1f.1)
30 SUBSYSTEM=="block", ENV{ID_CDROM}=="?*",
31 ENV{ID_PATH}=="pci-0000:00:1f.1",
32 SYMLINK+="cdrom", ENV{GENERATED}="1"

34 That looks ok but I don't think I'd know if it were totally wrong
35 either. I've renamed it and will reboot later on.
