Sony DRU-500AX - always damage sectors?

My Sony DRU-500AX is reporting all the sectors as damaged (yellow) in Nero´s CD Speed when making a DVD scan.

This happens to all kind of media (DVD±R, DVD±RW and
even with original pressed DVD ROM)

But when I play the DVD´s (of all kind of media) they seem to work just fine.

Is this a software bug(CD-SPEED fault) or is my drive defective?

My firmware is 2.0f and I have ASPI v4.72 drivers installed,
Nero 5.5.10.20 and the drive is in primary channel as Master and
an LG 8520B CD-RW as slave.
My HD is a Seagate Barracuda 80 GB Serial ATA.

Thanks in advance
