[QUOTE=Ibex;2784604]Is that drive in an external enclosure? What write speed did you select?[/QUOTE]
16x, connected via internal SATA.
The drive probably decided to limit the speed part way because it wasn’t happy with the writing quality, or possibly to avoid buffer underruns if the incoming data flow was insufficient.
Use the ‘Create test disc’ function and post a copy of the result. This will write a disc and record the actual write speed & buffer level throughout the writing process. If the drive has limited the speed again, scan the disc and see if the point where the drive intervened correlates with an increase in errors.
(If you don’t want to waste a disc, CD-DVD Speed can perform the same write test using an ISO image file as the source, rather than writing random data.)
Cool. I have an older copy of it, 220.127.116.11, that I’ve never actually used from an old install of Nero. Would that be sufficient? Or should I try to find this 18.104.22.168 one that everyone uses?
@bilditup1: It seems the drive probably indeed decided it didn’t like the quality of the burn to that point, as Ibex pointed out. The decision to fall back to 6x isn’t unheard of for Pioneer drives (occurring almost as readily as with old Plextor drives), especially for 16x burns. No guarantee choosing a 12x or 8x burn would have coerced the drive to avoid falling back to 6x, either. Maybe the next burn will be fine.[/QUOTE]
Aight, so this is within the realm of normal behavior. Good news. Thanks! I may still investigate it the way Ibex suggested but I’m less worried that there’s something wrong with the drive now, which would be relatively costly to replace
