Sony 710A changes mind about MXL RG/02

Hello, all.

I have a partial spindle of Maxell DVD-R discs with MID of MXL RG/02. I know I’ve burnt them in the past as it’s a partial spindle–half missing. I’m pretty sure I’ve never burnt anything at 1x before–the lowest speed this drive offers on any media capable of it is 4x.

Looking at the info in the firmware with OmniPatcher 2.4.2–on the firmware files that I’ve used to program the drive–shows that for this MID code, the drive should want to burn at 4x (only chosen speed). But, when a disc is inserted and DVD Identifier (or Nero InfoTool) run, it reports 1x as the only known burn speed. Sure enough, using Nero to burn a disc results in a 1x burn–with really bad PI/PO.

Any suggestions on what I should look at? Should I reburn with a known good firmware? Is there some chance that the EEPROM got corrupted? I did save a copy from some time ago, so I’m not totally hosed.

I only have a partial spindle of these things left–and it was a 25 disc spindle at that! So, I’d just like to burn these dozen or so discs and forget about this MID forever. Has anyone seen an error condition like this before?

Thanks!

I just tried an obscure piece of double sided -R media and got the same kind of results. DVD Identifier says the drive wants to burn it 1x while the firmware (as reported by OmniPatcher 2.4.2) says that it should only offer 4x.

Strangely, it still seems to like the CMC MAG. AE01 which it reports it will burn at 8x max. Strange.

Has noone ever had this problem with their drive? I know my drive has been a complete PITA–well, mostly Sony support was, but I wouldn’t have had to call if the drive had come with functional firmware in the first place–but this is silly.

Possibly, I need to backup the EPROM and do an LMR on it. I can always load the old EPROM back in if things don’t go well.

what firmware’s in on your drive?
try liteon’s CS0P or sony’s BYX4. these are the best firmwares for my 710a. (and i thinnk for others, too)

It’s BYX4 with patches to the media table by OmniPatcher. I also selected the Ledfix so the LED actually indicates what the drive is doing–and doesn’t make the light on the IDE bus steadily blink.

I’ve been really happy with this firmware–in general. If it weren’t for this one little problem. :slight_smile:

thanks, chok0

A little more information came to light today. I was looking through a directory of ‘junk’ on my PC and came across a list of media identifications I had done when I first installed BYX4 on this drive. I found two types of media that look funny.

So, though the drive can see that the manufacturer intended the media to be
faster, there is only that 1x write descriptor available. Strange.

Staring at it more, all I can see is that it doesn’t mind 8x rated media–that gets burnt at 8x. But, if the media is 4x, then it only gets recognized for 1x burning.

Could there be a problem with the BYX4 firmware WRT 4x -R media? Maybe something was done to it when the 12X -R ability was added. Just an idea.
