Please can you help me flash my OPTIARC DVD RW AD-7170A to Firmware 1n8_rpc1.bin on a MacPro 8 Core. I'm trying to get the drive to record (DVD+R DL) My details and problems are below:

PROBLEM:
I have the .bin and necflash on my desktop and when I put in this command:
/Users/myname/Desktop/necflash -flash -v 1n8_rpc1.bin A:
I get this error:

Identified drive: 29 - 3038
Detected drive from Firmware: -1
Supplied file does not contain a valid firmware

Is there something I'm doing wrong as this is happening with all Firmware versions?
Thanks for any help in advance

Have you not read the important message before downloading the patched firmware??

Please note that flashing these drives will currently not work in UDMA 4 mode. Please use PIO mode instead. Not doing so may result in an "Error submitting checksum" error message.

Also, why do you think your drive cannot burn DVD+R DL media??
And finally, which size does the downloaded firmware have?

Hi
This will sound daft but, I've been trying to burn +R DL and always get Failed Verifications and Unreadable Sectors. I thought a firmware Update might help? It may just be a bad .dmg that I'm trying to record.

I'll look into the UDMA 4 and PIO but I'm new to this jargon.
The downloaded .bin is (1,835,016 bytes)

I'm not sure if there is a way on a Mac Pro to disable DMA mode with a shortcut etc...

I think it's just cheap/bad or unsupported DVD+R DL media you are trying to burn. What media/brand is it, and rated for which speeds?
Verbatim DVD+R DL and DVD-R DL media should work fine.

From the firmware description it seems that Liggy & Dee patched other 7170 firmwares with newer DVD+R DL strategies.
But maybe Liggy could tell you more about this.

The 1.N* firmwares on the AD-7170A were made for the already updated bootcode that fixes the flashing in UDMA mode.

The error message indicates that Binflash was not able to detect a firmware in the file supplied for flashing. Looks like extracting the file went wrong. I just checked the 1.N8 package at work and it looks OK on first sight, however I cannot do any flash testing since I don't have a compatible drive here. These are the md5 sums for 1.N8:

However I doubt that downgrading firmware from 1.NC to 1.N8 will increase compatibility.

Hi Liggy

Yes Checksums are the same as mine. No worries I'll try Verbatim DVD+R DL, this will be my third make of DVD. If this fails then I'll get another .dmg to burn.

Thanks for all your advice too.
