OPTIARC DVD RW AD-7170A issues with reading DL DVDs

I've been trying with the above mentioned tools to no avail. I keep getting a 'command not found' reply in terminal. I've double clicked on the Binflash utility and it listed the commands in terminal

Can't belive it worked! Thank you so much! 🙂

I've been struggling on this for months, if not years!

Lars, read carefully these instructions and remember that I'm not responsible to any damage that you could do to your computer by doing this:

1. Copy necflash to the /usr/bin folder (to reach there Finder > SHFT+CMD+G and enter the name of the folder);
2. Download and unzip the 102c image: http://liggydee.cdfreaks.com/disclaimer/en/7170a/102c.7z.html in any folder (I suggest you to use your home folder, it's where Terminal starts);
3. From this folder, open a terminal window;
4. Scan to know the device's reference: necflash -scan (in my case was A:);
5. Backup the original FW in case of something goes wrong: necflash -dump OldFirmware.bin a: (the a: is the reference to the device that you'd got when running -scan it will take some minutes, wait for it until the prompt line appears again);
6. Finally, flash the new FW: necflash -flash 102cbt_rpc1.bin a: (again, the a: is the reference to the device that you'd got when running -scan);
7. Accept the terms (I think it's twice) entering y [enter] then y [enter] again;
8. Wait until the prompt again (don't do anything while waiting).

If anything goes wrong, flash again with the your backed up FW: necflash -flash OldFirmware.bin a:

Good luck!

Mario, thank you! Your directions were clear and staightforward. It was like you were holding my hand. You're the bomb 😉 Cheers

Thanks and you're welcome!

There is one side effect that I noticed until now: I can see the driver light thru the holes of the front grill, but I can live with that as long this means that I don't have to spend cash buying another optical drive. 🙂

Hope everything went fine! Cheers!

Mario, I am trying to do the update mentioned above but am not very computer savvy when it comes to using Terminal. Your directions are very straightforward but I'm afraid I donn't know "exactly" what to type in Terminal and all I get is "command not found" when I type necflash -scan at the prompt.

Can you do a very simple walkthrough for me?

Thanks
