12 HW problem would probably be most likely, I guess. Maybe a loose cable
13 if you're lucky. :)
15 You can also check the file:
16 /etc/udev/rules.d/70-persistent-cd.rules
18 To ensure it's got your device name right, or delete it and it'll
19 auto-create it at next boot based on detected hardware.
21 You can also use "hdparm -z /dev/hdc" to have the kernel re-read the
22 drive (without need for reboot), which should create the udev nodes if
23 it succeeds. I have a USB drive that always fails on first plug-in,
24 but if I use hdparm like that it'll work the second try every time...
26 Good luck!
