Greetings to all!
I currently have an Apple Mac Pro that has dual HL-DT-ST GH41N "Super Drives" installed. These are the stock Apple branded drives that came with the computer, and currently have whatever firmware the machine shipped with installed.
I was wondering... Is there any way to enable DVD-RAM burning on these drives? They'll read DVD-RAM, but they won't write to it. From what I can tell on the internet, the drive itself might support this (though I can't be sure)- and the firmware dumps I just took from either drive refer to a "HL-DT-ST DVDRAM GH42L" when you run `strings` on the main and core firmware binaries.
I've got a whole bunch of DVD-RAM's sitting here that formerly worked fine with my old 2006 Mac Pro (which I flashed the Pioneer drives on so they'd write to DVD-RAM, since Apple's firmware wouldn't do it), and I'd like to make one last ditch attempt to see if I can get the GH41N's writing to the disks before I go and buy an external drive instead.
So... Is this possible? Or are these drives physically not capable of writing to DVD-RAM (though, in that case, I'm puzzled as to why the firmware seems to be based on that of a DVD-RAM drive)?
Yes it is possible indeed ... and it is easy to do so as well. GH4xN drives are basically an OEM version of the LG GH22NS40 retail model. They can therefore be flashed either with the retail LG firmware or with any other OEM GH4xN DVD-RAM enabled firmware, and that will enable DVD-RAM burning for you.
Basically, if you want to flash the drive with the retail firmware, then download the GH22NS40 NL02 firmware, extract the firmware binary from the *.exe update package using the -r option in DevilsClaw's flasher, and then flash the main part to the drive and do a full shutdown. There is no need to flash the core part, so leave that alone.
Presumably your current firmware is a PQ0x version?
