It apparently has a Sanyo LC898098Y UD9 as the chipset but that's all I can find after some googling.

PX-750A is not a real plextor drive so don't buy it.. I would choose the PX-755A (especially since it's cheaper price there than the 716)

It isn't a authentic Plextor drive, and doesn't understand D8 command, packed mode for CD+G and so on. However, it exposes, aparently, very excellent capabilities in error correction with worn discs, better than real Plextor drives. This is the favourite drive of Spoon, the dBpoweramp's developer.

Working Plextor drives (tested by me): PX-712A, PX-116A

For example any PX-7xx, except 740, 750 and 751. Today, Plextor drives are actually others (Lite-On, LG, Pioneer, NEC...) rebranded by Plextor and they doesn´t offer any special feature.

Does anyone know if the newest Plextor drives still support  d8h?  Looking at purchasing a drive to replace one that is dying and was looking at the PX-L890SA.  http://www.newegg.com/Product/Product.a … 6827249066

They don't.. PX-760A is the last one that supports it

This new method expands upon our previous discovery, and also proves that our current methods of correcting both offsets are correct.

The principle is that, by using the D8 vendor read command on compatible drives, data sectors are read in audio mode and thus become scrambled. The sync remains unscrambled, and its position can be used to determine the combined read+write offset.

Advantages over old method:

- Works on all discs with data tracks
- All data track sectors can be used to detect

Disadvantage:

- It requires a drive that supports the D8 read command. Most Plextor drives (original ones, not rebadged) are confirmed to support this command (755A, 760A, etc).

Software needed:

Px_D8 v1.01A by Truong Hi and Dremora - http://soft.dremora.com/px_d8_1.01A.7z

Usage: px_d8 <drive letter> <LBA sector>

For LBA sector you can just put '0' or any number. If your drive supports the command, it will give you the Combined offset (the offset that is used in EAC for dumping audio tracks).

Precautions:
- If you have a Plextor drive, be sure to update to the latest firmware available for your drive!
