I've just put to rest my Pioneer DVR-106D and got in place a brand new DW1640. And the problems started...
I tried to burn 4 DVDs, all got bad sectors (Nero data verification failed, binary compare with the source failed).
The media is Memorex 8x DVD-R, CMC MAG AE1, which worked flawlessly with the Pioneed drive.
Tried to write at 8x, tried at 4x, tried with BSKB, tried with BSLB, no matter what I tried the bad sectors kept appearing.
I doubt it's the Memorex batch fault, because I've already burned about 60 from a 100 pack with NO problems on the Pioneer.
The system setup has not changed, the drive is in an external enclosure, connected through Firewire, as it was the Pioneer.
I've read that Benq likes +R more than -R but I didn't believe it could be such a problem. And I still have 30+ dvds. I'd just hate to throw them away.
Does anybody have any ideea of what might be the problem?
