A plextor 716UF, an external combo DVD-CD burner, is not burning at even 8x reliably. The Win XP Pro NTFS single HD is fully defragged, there is 512 megs of ram, 30 gigs free space, there are no other applications using CPU, Nero is updated, notebook bios is updated, plextor firmware is updated, and using 8x media recommended by plextor
And yet the burner frequently times out -- not coasters mind you. It burns, pauses, burns some more and averages 45 minutes to burn a full DVD when at 16x burns should average 6 minutes, and at 8x should average 12 minutes.
The 716UF can connect either via USB2 or Firewire. The laptop supports both USB2 and firewire. Neither connection mode seems to effect a speed improvement. Various forums suggestion solutions to sluggish *internal* burners by verifying DMA is enabled and such... BUT this is an external drive and therefor DMA, AFAIK, is not a factor. No discerable difference whether HyperThreading is enabled or disabled.
What tuning options are availble? How can more than 4x be coaxed out of this 16x burner?
