CD/DVD drive not working properly

Hey to all,

1) OK, I have a SONY DVD RW AW Q170A and a Lite-On SHM-165H6S. The first one (Sony), doesn't read blank DVD's, it just says "error, blah blah" but it should read AND write. The other one (Lite-On) is a Light scribe which which works fine. Saying both to see (hope?!) it's not a jumper slave/master issue, but I dont think so.

Question: I know I read I could upgrade the firmware, should I do this and, yes I know RPC but to what specifically? I read that this drive is old and was bought out or something (?) and it could be flashed with another brand? Am I insane or does this ring a bell with anyone? Thanks in advance!!!!

Also, 2) got 4 GB Ram, BIOS reads it, some apps (CPU-Z) read it, but Windows SP2 says 3 GB- BEFORE it said I had 4GB - what the hell happened?!?

Thanks!!!!

This isn't an ODD forum... you might want to try a place like CD Freaks--they have a great LiteOn/Sony forum with plenty of info about crossflashing (I should know, I used to moderate it

).

32-bit Windows cannot use all 4 GB since some of the address space is needed for things like DMA.

Haha, well, it's "general." Will ask over there, thanks.

Strange thing with the RAM though is it previously showed 4, and no new hardware was installed after. I'll figure it out, get under the hood of it. Just wondered if it was an SP2 issue since I don't have SP3 :gasp!:

And please do read the FAQs stickied at the top before asking; the moderators like it when you do that. They may be old, but still mostly relevant. Plus, I'm a fan of the guy who wrote them.
