Mine came with 1.21 firmware, nero INCD would not format the disc without errors, then puking the disc out about 10 minutes after the formatting started. Took the drive back to the B&M for a swap, second drive with 1.00 firmware did the same thing with the included RW disc. Went and bought a maxell DVD-RW disc and it formatted fine. Hope no one needs cendyne tech support, what a joke. 3 days of on and off calling about the problem only brought "all our technicians are on other calls, leave a message with a time for us to call you back..." 5 days later still no callback.
anyway, count me as one who could not get the included RW disc to format. DVD-R works, and with a decent quality RW disc that works great too. Burnt my first DVD-r disc with 4.2gb of data.. WOW.
