atapi/dvd writer detected as ide-tape

[Thomas Drillich]

Hi,

I've got a LG GH22LP20 DVD writer
http://www.lge.com/products/model/detail/gh22lp20.jhtml

it worked for a few days, but after a reboot it never detects it again.

Does somebody knows howto get it running again ?

I found in the syslog:

a tape is a tape..., a dvd is a dvd...
i think either your udev rules are broken, or you modprobe the wrong
ide-controller driver
