Definitions:
------------

GDA is LG RH series

GSA is LG manufacturer

GWA is OEM like Dell, Compac,

All are cross flashable as they are really the same type of drive, you just need a patched flasher.

The H**N are normal drives
The H**L are lightscribe compatible

I believe the 'L' (lightscribe) versions 'MIGHT' be able to be upgraded to SL40,
but I have no drive to test.

The 'N' versions are NOT upgradable to SL40 as they have a different chipset.

When replacing an original drive by a replacement drive never use EJECT button of replacement drive.
It will run out of control! Use only recorder EJECT button!
