Re: Problems when writing DVDs with growisofs
Folks! Do math first! Dataset size was reportedly about 4.4GB, while I/O
error logged at 4GB *exactly*. It can't be some prefetch/pad bug! It
looks as if kernel can't manage volumes larger than 4GB *at all*. Or at
least refuses to...
The problem has been "solved" (moved):
For the device of my DVD-burners there was "pktsetup" (for writing to
DVDRAM) called via a initscript from which I dont know that it was
This is misconception. pktsetup is not for DVD-RAM, but for CD-RW packet
writing, but can as well be used with DVD-RW Restricted Overwrite and
DVD+RW [at least as far as I understand].
Ok, I can now read my DVD successfully and completly.
So that packet writing module limits volume size to 4GB? Talk to the
maintainer... readcd worked because it bypasses block device and issues
raw read commands to its liking.
But it remains the question, why I should not read my my DVDRAM now
You should not have any problems reading or writing DVD-RAM with pkt
module disengaged. Nor should you have problems *reading* any kind of
DVD media and writing with growisofs with pkt module disengaged. A.
