Well, I've been in and out of this forum looking for a possible solution to my problem but have had no luck so far. So, sorry if I missed a thread out there that already addresses my problem as this may be a repeat.
Ok, the problem.
I have a 740a drive that has been giving me nothing but problems with DVD DL from the start. I've spoken with Plextor support and they couldn't help, actually the tech I spoke too seemed intimidated by the issue and basically gave me a "good luck with that" response.
This drive has no problems burning SL media. It's the DL that's a problem. Every time I put DVD DL media in the drive it Windows recognizes it as a blank CD. Nero also calls it out as a blank CD but will still burn it to the fullest capacity the DVD DL allows. Basically burns a nice coaster for me.
I've tried with the 1.01 and 1.02 firmware and there is no change. I've tried all sorts of media manufacturers, Fuji, Verbatim, Memorex, Maxell...you name it, same outcome.
Having read a few threads here I thought I might try crossflashing it with the BenQ 1640 firmware. Each time I try to flash it I get an error " The drive is not allowed to be updated". Tried this with the BQflasher and straight BSRB.exe.
Needless to say I've had enough. I'm ready to go and get another optical drive to replace this pile but I want to make sure I've exhausted all possible efforts.
Help me CDFreaks...you're my only hope.
