I have Optiarc DVD RW AD 7173A.
Here’s the problem: since the day before yesterday 90% of all my DVD burns fail, regardless of the software I’m using (Nero, Imgburn or CDBurner XP) or the writing speed.
I’ll post a log later, but roughly the situation looks like this:
some heavy buffering during the whole burning process regardless of how many processes are running (this used to always happen before but never caused me any problems), -> near the end of the burning process there is some pretty long buffering going on (again, this used to happen, no problems before), -> “burn process completed successfully”, -> verification -> “error reading sector XXX”, “error reading sector YYY” around 80-smth% -> Made some software changes -> Same thing, but now the errors always seem to happen at the 94% stage.
I must say I used two obscure brands of DVD-R discs (only 2 out of 22 discs burned fine) PLUS three Verbatim discs which all burned successfully, BUT I used to burn obscure crappy DVD s before, and the failure rate was very low, so why can this be happening now?
I tried several writing speeds and three kinds of burning software.
I read somewhere that Nero could interfere with other burning programmes, so I completely uninstalled Nero, but it didn’t help.
I also downloaded the most recent firmware for my drive, ran a “Reset DMA” utility, and even used a lens-cleaning disc. :-/ Nothing changed.
Did anyone have similar experience?
