lite-on LH-20A1L

[AZ Nomad]

Has anybody been able to get a lite-on LH-20A1L dvdrw to work?

My motherboard has two SATA controllers, an nforce4, and a sil3114. The
dvdrw doesn't work with either.

Am I missing some driver, one for SATA optical drives?

The drive shows up in dmesg, and /proc/scsi/scsi, but it doesn't get a drive
letter and I can't mount or give it an eject command.

Dmesg:

My system has an PATA nec dvdrw and that is all that comes in

Add it manually to your /etc/fstab
/dev/cdrom1 /mnt/cdrom1 udf,iso9660 noauto,users,ro 0 0

I didn't mean a DOS drive letter. I meant something like
/dev/sdb

If there's no dev, there's not much you can do in fstab.

I made some progress last night. I read after a google search that the old pata
driver "ATA/ATAPI/MFM/RLL support" conflicts, so I compiled a kernel without
it. What I got was a system where I lost my old PATA dvdrw and still didn't
have my new SATA dvdrw.

I returned to the kernel params and looked in the scsi area and tried the
scsi cdrom driver again. When I tried that earlier, it led to a system
that locked up tight during bootup. I figured that with the old PATA driver
gone, it might behave better. This time around, I got two new devices,
/dev/sr0 and dev/sr1, the PATA (sr0) and SATA (sr1) dvdrw drives!

success!

Well, not quite. dvd::rip hangs when trying to rip from the new sata
dvdrip. Back to using the old one for now.
