I’d have to say my best guess is it could just be the discs are bad because
with a failure rate of 20%+ it sure sounds that way to me. The only time I
ever tried the Optical Quantum brand of discs was with their DVD -R which
was a total waste of time and money.
I had such a high failure rate with them out of the first 10 or so discs that I
just decided to toss the rest of them in the trash can and made sure to put
the Optical Quantum brand at the top of my do not ever buy again list . :Z
