I am not happy seeing these two things together. I remember there are
Genesys chipsets which have limited transfer size, max. 32kib. I
implemented a workaround which looks in sysfs to retrieve the real
transfer size, but it relies on correct information displayed in the
sysfs. Please show the contents of this commands:
$ find /sys/ |grep max_hw_secto
$ find /sys/ |grep max_hw_secto | xargs cat
[EMAIL PROTECTED]:~$ find /sys/ | grep max_hw_secto
/sys/block/sr0/queue/max_hw_sectors_kb
/sys/block/fd0/queue/max_hw_sectors_kb
/sys/block/hdd/queue/max_hw_sectors_kb
/sys/block/hdc/queue/max_hw_sectors_kb
/sys/block/sda/queue/max_hw_sectors_kb
/sys/block/hda/queue/max_hw_sectors_kb

The drive is sr0 so this would seem to back up your theory. It isn't
however pulling it out of the system and modifying it I would guess??
And try using the ts=... parameter of wodim.
Eduard.
I'm not sure how to drive wodim manually as using k3b as my front end.
The above data does seem to confirm your theory. If you really want me
to test still I'll try and understand how to drive from command line.
