my cdrom refuse to burn dvd-r

[lessless]

hello! i've tried blank dvds bought in different places and wasted five discs - every time burn failed with scsi error in beetwen 70% and 93% of completition. my hardware is hp 530, kernel config is here http://pastebin.com/7LMLHqaF and dmesg output is here http://pastebin.com/MC4xkNgx

does that mean, that my cdrom drive is dead ?

lessless,

Is yoour DVD internal or USB ?

Your kernel is far from optimal as it has a lot of debug options on. This slows things down as it makes the kernel spam logs.
In turn that competes with your DVD burn for disk access.

How have you been burning DVDs?
Do you make an intermediate tmp *.ISO file, then burn the *.iso in ine big burn or do you make the *.ISO 'on the fly' ?
The latter is more taxing on the system as it should keep data supplied to the DVD all the time to avoid buffer under run errors.
However, most DVD writers now have a feature called 'burnfree' so that these errors can be managed and you still get a good burn.

Lastly, what do you have in your /etc/fstab for your DVD. You dmesg suggests you have it set to auto mount, which would account for the early dmesg log spam if the drive was empty at boot.

Fix your kernel to turn off all the options with debug in their names,
Fix your /etc/fstab to use the noauto option for the DVD.
Make sure you burner software uses the burnfree option

If you still get errors post the command that was sent to the burning program and the error you get back.
