I have posted about backing up my firmware, extracting the media table from the firmware and backing up my eeporm using the tools for the liteon PC based burners. I posted the extracted .bin firmware from my ddw-451s and it's extracted media table and my backed up eeprom along with thrunners firmware he got from his ddw-813s in a post I started in the LiteOn forum cause code65536 wanted to take a look at em.
Both firmwares are standard length (1MB) thet the pc based burners have. ala42 (the author of Media Code Speed Edit) was able to run the Media Code Speed Edit tool on both my and thrunner's .bin firmwares and it worked. When Orphee gets done trying to reflash his 5005 with thrunners .bin firmware and it works it looks like us 5XXX owners are going to have a whole bunch of tools to use. I been a little cautious about reflashing using the tools because one of the codeguys was not sure if they would work because they were not familiar with the 5XXX's drives and I have had no bad firmwares to try and recover from but am really thinking about trying it to see if all these tools will work writing to the ddw drive.
Intersting thing with omnipatcher run on my ddw-451s it identified as
Drive type: LDW-451S/851S
Vendor string: LITE-ON
Product string: DVDRW DDW-451S
Firmware revision: G2BD
Firmware timestamp: 2005/01/11 19:52
and ala42 said thrunners 813s id'd as a clone to the 1633s and a rebadged sony. It's all posted in the liteon forum.
This is gonna be fun. Orphee ya gotta let us know how the reflash went on your dead 813s
