Hello - I'm having some issues burning a dual-layer DVD. Yesterday I
burnt my last DVD+R DL disc (Memorex 2.4x) so I got another pack of
essentially the same, though this was rated at 8x. It looks like that's
the one difference between the two packs of discs. Now, whenever I try
to burn to these new discs, I get the following, apparently right around
the layer split:
50.08% done, estimate finish Thu Jan 10 12:28:35 2008
:-[ WRITE@LBA=1f7700h failed with SK=3h/ASC=73h/ACQ=03h]: Input/output error
:-( write failed: Input/output error
I know that this corresponds to "POWER CALIBRATION AREA ERROR" but that
doesn't help much... I've found plenty of other references to this
error online, but it looks like all of those are happening at LBA=0h,
right at the start of the disc, not at the layer transition.
Since my previous discs were just 2.4x, they were getting burnt at a
slower rate. I can't get these discs to burn at anything other than
4.1x, though. I've tried "-speed 1" and "-speed 2" but growisofs always
reports:
/dev/dvd: splitting layers at 2061632 blocks
/dev/dvd: "Current Write Speed" is 4.1x1352KBps.
0.12% done, estimate finish Thu Jan 10 18:26:46 2008
Nothing shows up in dmesg during the burn process. Mostly I'd just
really like to find a way to force the burn process to go slower. It
seems that the most major thing that's changed is that it's trying to
burn faster, which I don't really care about. If I could get it to burn
at 2x (I'd even settle for 1x at this point) and have it work, I'd be
fine with that.
The new, blank discs look like this with dvd+rw-mediainfo:

It looks like under the "Speed Descriptor" sections that the slowest the
disc will support is 4.0x... Is there any way to override that?
After the (failed) burn, the disc looks like this:

That disc was burnt somewhere around 2x. Presumably it had given me a
note about burning at 2.4x at the beginning of the burn.
So, any ideas would be appreciated. I suppose I could go see if there's
an updated firmware for my drive, perhaps that's what's needed here...
