DVD burning problems

[david at thekramers.net (David Kramer)]

So I have one of these:
http://www.compusa.com/products/product_info.asp?product_code=334029

I haven't used it in a few months, but I'm pretty sure I've burned DVDs
to it before.  But now I can't burn DVDs, not even data DVDs.


Ferinstance, I created an ISO of a Suse 10.1 DVD using dd.  I know that
part worked, because I could mount it with -o loop and see the files.
But this is what I get:

# growisofs -dvd-compat -Z /dev/sr0=suse10_1dvd_1.iso
Executing 'builtin_dd if=suse10_1dvd_1.iso of=/dev/sr0 obs=32k seek=0'
:-[ READ DVD+R DL BOUNDARY INFORMATION failed with
SK=6h/ASC=28h/ACQ=00h]: Input/output error

I noticed the following in /var/log/messages:
Aug 22 00:17:44 deepthink kernel: SCSI error : <0 0 0 0> return code =
0x8000002
Aug 22 00:17:44 deepthink kernel: sr0: Current: sense key: Hardware Error

sector 13902792
Aug 22 00:17:44 deepthink kernel: Buffer I/O error on device sr0,
logical block 1737849

But I didn't see those messages again after retrying it.


I also tried
deepthink:/dload/graphics/tmp2 # growisofs  -Z
/dev/sr0=/dload/iso/suse10_1dvd_1.iso
Executing 'builtin_dd if=/dload/iso/suse10_1dvd_1.iso of=/dev/sr0
obs=32k seek=0'
/dev/sr0: "Current Write Speed" is 4.1x1385KBps.
:-[ WRITE at LBA=70h failed with SK=5h/ASC=21h/ACQ=02h]: Invalid argument
builtin_dd: 112*2KB out @ average infx1385KBps

This is the info on the disks after:

This is with Memorex DVD+R Double Layer media.  Am I doing something
wrong, or is this thing broken?
