problem burning DVDs on LG GSA-4163B under Sarge (2.6.8-2-k7)

Hi

I am having problems burning DVDs on a freshly installed Sarge system,
using kernel 2.6.8-2-k7. CDs burn without issue, but I get the
following error when trying to burning DVDs

lnx5:/data/ram# growisofs -Z /dev/hdd -dvd-compat -R -J h2g2
Executing 'mkisofs -R -J h2g2 | builtin_dd of=/dev/hdd obs=32k seek=0'
/dev/hdd: "Current Write Speed" is 4.1x1385KBps.
:-[ WRITE@LBA=10h failed with SK=3h/ASC=0Ch/ACQ=00h]: Input/output error
:-( write failed: Input/output error
/dev/hdd: flushing cache
:-[ SYNCHRONOUS FLUSH CACHE failed with SK=3h/ASC=A0h/ACQ=80h]:
Input/output error
lnx5:/data/ram#

as both a normal user, and as root.

Any ideas?

Cheers

Adam
