Hi Gang,
Just wondering if anyone else has seen a depressingly high failure-rate
for blank dual-layer DVDs. For me, it seems like a good 40-50% of my
blank discs crap out during burn at the layer switch; growisofs says
":-( write failed: Input/output error" at 49.6% completion. (It's so
close to 50% is why I suspect something going wrong at the layer switch).
Or is it something I'm doing wrong? Most often I'm burning single-layer
media, either CD or DVD-RW. Is there something I need to do to tell the
hardware to expect to have to do a layer switch? I sort of expected the
drive to figure that out on its own.
My growisofs command is thus:
growisofs -Z /dev/dvdrw=dual-layer.ext2
where dual-layer.ext2 is a ext2-formatted 8.0GB loopback file I use as a
staging area for creating backups and such. When it doesn't crap out at
49.6%, it works fine, so it makes it difficult to figure out if I'm
doing something wrong.
Cheers,
~Brian
It may seem silly, but I was having the same problems with
the prodvd-cdrecord and it was recommended I use K3b.
Since switching over, I haven't had any problems.
Also, which dvd burner are you using? Have you checked
for firmware updates?
