DVD-R loses media information after burn

RobM 2004-12-29 19:24:51 UTC #1

I've flashed my 832S using the VS0E firmware with the latest recommended tweaks applied in OmniPatcher. This gave me great results with FUJIFILM03 media, strat-swapped to TYG02.

However, after I've burned to the disk, nothing can detect the media ID anymore. It has done this with the last 2 out of 3 DVD-R disks I've burned, but not the first one I burned after the flash. All are the same media.

This is what it looks like after burning: (Notice the max burn speed!)

Disc Type DVD-R
Book Type Unknown
Manufacturer
Media ID
Protection System None
Region 1,2,3,4,5,6,7,8
Capacity 4.36 GB

Track Density 0.74 um/track
Maximum Read Speed 0.0x
Maximum Write Speed 9.691E4x

Blank and previously burned discs are detected fine, just like this one:

It has only started doing this after the last time I flashed the firmware. It can read the media information from DVDs I wrote before the flash.

Could it be that the strategy swap from FUJIFILM03 to TYG02 means it ends up overwriting some of the lead in info or something? Has anyone else seen this?

I'm using Nero 6.3.1.25, using either an ISO file created from DVD-Shrink or Nero's DVD-Video settings.

I don't know if its actually a problem, cos now I can use up the rest of my Fuji disks instead of producing coasters. Just a bit worried, I didn't think that that area of the disk could be written to.

Hm. Strange. Shouldn't be doing that, even with strat swapping. Is the disc itself readable?

RobM 2004-12-29 19:36:15 UTC #3

Thats the thing, it's one of the best I've burned.

Don't have anywhere to put a picture of it so here's the main bit from K-Probe:
Speed: 4x
ECC Blocks Sum (PI/PIF): 8/1
Errors: 0
PI Max = 13, Average 1.21, Total = 20608
PIF Max = 3, Average = 0.05, Total = 899

Edit:
Oh, being DVD-backups its using all the disc. I'm about to try one now using less space.

Another edit: Added some stuff to a multisession DVD I've got and it still has its media info intact. I had another look at one of the wierd discs and I've just noticed that if you view the unrecognised disc's info in Nero, it says the booktype is DVD-ROM, How is this right for a DVD-R? The discs that show with no media ID are all apparantly DVD-ROMs, and the ones I burned a few days ago which do have the media ID show up correctly as DVD-Rs.

Relaised when I flashed it, I'd use the patched crossflashed version. Did it again with the stock version (+ recommended tweaks) and the first disc I burned came out fine, still detects the media code. The first one after the flash was OK last time, I'll have to see if the next one I do is OK.

Just for info, the scan of one of the discs with unrecognosed media is attached. Looks fine to me.

RobM 2005-01-03 20:02:42 UTC #5

Nope, the next ones I did lose the media ID again. Looks like only the first one after the flash is fine. Does the VS0E firmware have some wierd bitsetting thing? I haven't got autobitsetting turned on and just leave nero set on DVD-ROM for when I burn a +R disc.

code65536 2005-01-03 20:37:50 UTC #6

Weird. I wonder... does another application, like, say, DVD Identifier work?

RobM 2005-01-03 21:15:46 UTC #7

Nope, it is indeed wierd. I've checked a disc I just burned, the one I burned just after a the last flash, and one I burned a while ago that is OK.

The ones burned with VS0E + strat swap come out as DVD-ROM, but the first disc burned after the flash is recognised while the next one isn't.

Oh by the way, they did all have media codes before the burn, I've been checking every disc since this first started, just to be sure.

Do you think its worth resetting learnt media and then seeing after the next couple of burns? I've never done this before as I thought it was done due to the new firmware. I'll also be getting some different -R media (when the delivery company finally comes back after xmas...) so can try with that.

RobM 2005-01-04 09:06:52 UTC #8

I've checked one I burned with stock VS0E and that is recognised OK too. Looks like its the strat swap thats causing it?
