I know this is crappy media, but Verbatim is 50% more expensive. Thanfully I only bought one disk.
However, this media is supported by pioneer(3 writers), sony(3), Lite-On(3), HLDS(4), Plextor(3), BTC, Cyber, Philips, Hp, Aopen and BenQ.
NO NEC DRIVE supports them, not even the newest 3540 ! :a :a
Crappy DL media support, no error scanning (for 3500), I guess this is what happens when a company only cares about its OEM sales.
