FWIW, TSST stands for Toshiba Samsung Storage Technology, a joint venture
between two monster electronics companies. Not much of a web site though. A
lot like Toshiba, who manufacture lots of 2.5" notebook drives, provide zippo

drastic change, I would not count on TSST for anything. Firmware upgrades for
CD-RW and DVD-ROM drives are fairly rare... Ben Myers
