I have a TSSTcorp CD/DVDW TS-L632B, firmware TM31, made on 08-02-05. It's a bulk model, and came with a Samsung X20 XVM 1730 II laptop.
TOSHIBAer told me that the drive has the following specifications:
5x DVD-RAM, 8x DVD-R, 8x DVD+R, 2.4x DVD+R DL, 4x DVD-RW, 4x DVD+RW, 24x CD-R, 10x CD-RW.
According to the list on http://firmware.toshibaer.de, it is the same as Toshiba SD-W4172C.
The SD-W4172C is even more unknown though, sadly.
Now I've been looking for firmware updates, and neither TOSHIBAer's firmware page nor Samsung's ODD department website have any.
Do I need to replace the drive to enjoy better support for new media?
