Can anyone who owns the Sony DRU-810A confirm that it can overread into both the lead in and the lead out of audio CDs? I’m thinking of purchasing the drive to use as both a DVD burner and an audio CD ripper. Since I’m picky about making exact audio copies with EAC, all the little DAE details matter.
However, I learned herethat the DRU-810A uses the same hardware as the BenQ DW1640 and the Plextor PX-740A, and those two drives apparently are unable to overread into the lead out â€” only the lead in, which is useless for ripping because they require a positive read offset correction (+618 according to AccurateRip).
If all three drives are based on identical hardware, then how can the Sony overread into the lead out while the other two cannot? Am I correct to surmise that overreading is a firmware-dependent feature, and that only the Sony’s firmware supports reading into the lead out?
If this is the case, then cross-flashing the 810A with BenQ’s or Plextor’s firmware would remove the drive’s ability to overread into the lead out. And as no firmware for the Sony can be downloaded yet, cross-flashing is an irreversible action at the moment.
Conversely, this would suggest that the firmware for the BenQ and other drives could be modified to enable overreading into the lead out.
(Note: The two reviews I cited show different combined read/write offsets for the 810A: CDRLabs reports 756 samples, while cdr.cz has 684. This discrepancy, I believe, is explained in the thread about the BenQ DW1640’s offsets.
