Professional Geekism

I recently needed to burn a copy of Windows 7 Pro but realisd that I’d unfortunately run out of blank DVD-Rs long ago. Fear not, for I live near an Aldi supermarket, whom sell everything dirt cheap. DVD-R’s a DVD-R, right?

Wrong. I tried at least three of the twenty I purchased (for a few quid) and none of them would even begin writing. Brasero/K3B both complained about incompatible media types.

Remembering that my DVD drive, a trusty NEC 3500A, was designed, built and purchased somewhere between 2004 and 2005 (4-5 years ago at this point) and that I hadn’t ever updated the firmware, I set about researching ways and means into doing this.

I came across this website, run by a pair of firmware hackers named Liggy and Dee whom have (between them) released, and continue to host, many firmware releases (both official and unofficial) for a wide variety of NEC optical drives.

What’s more, their binflash (or ‘necflash’) utility was even released as a Linux binary and it even provides compatibility for reading the official NEC .exe firmware releases! I was sceptical that it would work under Ubuntu 9.10 at first, but much to my delight it worked perfectly. With a little reading, I was able to dump my current firmware (2.16) to file and subsequently flash two different firmware releases: 2.58 (an OEM firmware release) and the latest, official NEC firmware 2.1A release.

The full output of my escapades for anyone curious:


~$ sudo ./necflash -flash -v -s Desktop/NECND350_v21A.exe /dev/sg2

Whilst the 2.58 OEM release didn’t fix my problems, 2.1A did and I now have a freshly-burnt copy of Windows 7 Pro to go and play games with. Nice one, Liggy & Dee.
