tsstcorpfix1.txt

This is a fix due to problems with TSSTcorp DVD drives.
(TSSTcopr CDDVDW SH-S223C)

In /lib/udev/rules.d/60-persistent-storage.rules, comment out:
# ATA/ATAPI devices (SPC-3 or later) using the "scsi" subsystem
KERNEL=="sd*[!0-9]|sr*", ENV{ID_SERIAL}!="?*", SUBSYSTEMS=="scsi", ATTRS{type}=="5", ATTRS{scsi_level}=="[6-9]*", IMPORT{program}="ata_id --export $tempnode"

Add
options libata atapi_passthru16=0 force=5: udma5
to /etc/modprobe.d/modprobe.conf

Add
FILES="/etc/modprobe.d/modprobe.conf
to /etc/mkinitcpio.conf

Rebuild kernel image with:
mkinitcpio -p linux

reboot
