You mentioned that your drive failed to drive to write to DL DVDs, so I'm wondering how exactly is that? I also have a 1640 that's 2 weeks old and my drive spikes really high on all DL media,I've already wasted two Verbatim 2.4x (MKM 001) and one Ritek D01. The Verbatims were written @ 2.4x & 4x and the Ritke was written @ 2.4x.
Should I RMA the drive or what?
The drive also spikes really high on +R media( MCC004) ,not just @16x (though I get 40+ PIF after 3 GB at 16x) , but at all speeds.
