NEC drives are looney for scanning, and 8X is most of the time the worse scanning speed with these drives. Try 5X (forum standard for NEC) or 12X (my personal favorite with NEC) and see if things look better.
PIE will always be much higher in NEC scans, but PIFs shoudln't go mad like that if the burn is very good. Now you have to know that 3550/4550 are also very inconsistent from scan to scan with the same disc.
Just wondering, would the 3550 happen to be in an external enclosure?
Even though the case you submit (NEC scan) isn't the best example, that's still an excellent point... :bigsmile: We are several to think that LiteOn scans are faaaar to forgiving and make about all burns look OK to great (at least at the "standard" scanning speed of 4X).
