CDRW/DVD Help

Anyone know of a site with firmware for a TSSTcorpCDW/DVD TS-L462A drive? I've done some research, and it's supposed to be a differently branded version of the Samsung drive with the same model number (TS-L462A). I've taken the suggestion on a couple of forums to just flash it with the Samsung firmware (U300, U301, and X301), but all that's done is finally kill the drive (it would only read DVDs before, but now it reads nothing). If I could find the HP17 firmware, that'd be awesome, since that one at least let it read DVDs.

I really need this to work since it's my laptop's drive...

Edit:
Nevermind. It's reading DVDs now. I'll have to wait until I get home to test CDs, though.
