- Introduction
Not so long time ago, a patched firmware released allowing users to "upgrade" the existing SOHW-812S->DRU700A adding the so called "Double Layer" burning feature. For various reasons the firmwares are not online anymore, but firmware for the 812S->832S "upgrade" is available! Both DRU700A and 832S are the exact same drives, so the testing was done anyway

- Burning Process

The burning process had 2 mysterious "delays"...

1)



As we can see the drive tries to become ready at 32:35, we press the continue button at 32:42, the drive continues not to be ready but finally at 32:46 recognizes the media

2)



At 32:48 the writing speed was requested however, the writing started at 33:28, 40 seconds later. During those 40 secs, the green led was blinking, we thought the drive halted when tried burning at the DL media however started burning...

3) The burning started



4) The burning finished with a total time of 38:39mins, higher compared with other DL recorders, probably due to the above mentioned delays

- Checking readability of the burned disc

a) Nero CD-DVD Speed v3.00 with the same drive (LiteOn SOHW-812S->DRU700A)



Perfect reading curve!

b) Nero CD-DVD Speed v3.00 Scan



The Scan results are not very good at Layer 1, but we believe the reported PI error rates are not realistic cause:

a) CDSpeed cannot set a low reading speed (1X/2X/4X), causing the drive to report high error rate
b) KProbe v2.1.0 can set for example 2.4X CLV but stucks at 50% at all times

I would suggest to wait a while until more tests are done about the DL firmware...

Very much agreed! There is not enough testing right now to want to flash the drive, other than we know that it can be flashed!

Best to stick with what is working now, than to risk trashing a drive.

As stated above by our destinguised members, Minos and Emperor, when this media becomes available, you will NOT want to purchase it, as it will be exteremely overpriced.. be patient and wait a bit..... 2.4x DL is a SLOW writing method... Let's say... wait and see what develops!

It won't (and it can't) trash your drive or damage it in any way. The only way to harm a LiteOn is to deal physical damage to it. Unlike a number of other drive types, a even a horribly misflashed LiteOn can always be recovered.

All that can be said is that in the absense of DL media, none of the DL hacking that's been going on with NEC or LiteOn is really worth anything more than just a proof-of-concept (and a cute novelty :) )
