לבעלי ה H10A של LG

GSA-H10A -> GSA-H10N

These two drives appear to be identical internally. The firmware revision code for both drives shows the string GSA-H10NMAIN, indicating that the firmware used for both drives is meant for the same drive. This alludes to the fact that the drives use identical hardware.

The H10N has more powerful features, which is the main reason behind cross flashing the H10A -> H10N :

H10A :

- 8x DVD+DL max writing speed

- 5x DVD-RAM max writing speed

H10N :

- 10x DVD+DL max writing speed

- 12x DVD-RAM max writing speed

The cross flash is accomplished by simply flashing the H10A with TDB's version of JJ11 for the H10N. However, due to the fact that the firmware used for the cross flash is actually based on Hitachi's version of the H10N, there are additional benefits :

- UDMA4 interface (H10A : UDMA2)

- hardware based automatic bitsetting/book typing (H10A : manual

bitsetting/book typing)

- DVD+/-R discs read at 16x max (H10A : 10x max)

- DVD+RW discs read at 12-14x max (H10A : 8x max)

- DVD-VIDEO single layer discs rip at 10x max (H10A : 5x max)

- DVD-VIDEO double layer discs rip at 8x max (H10A : 5x max)

These features have been verified to work correctly on the cross flashed H10N except 12x DVD-RAM writing. That feature has not been properly verified because none of the people who cross flashed their H10As -> H10Ns have been able to get hold of 12x DVD-RAM discs to test their drives. These discs currently appear to be available only in Japan. None of the testers currently reside there.

(Thanks to TDB for the modified firmware which makes the cross flashing process possible in the first place, the various people in the thread above who cross flashed their drives and ran tests and especially those who responded to my requests for information on certain features of the drive.)
