No Seek error with Nec 3500

I’ve a NEC - 3500 AG @ 2.18

Sometime when I’m burning a mini DVD-R (Dotcom//AML), this error occurs between 70 and 90% of wrinting ;(

sometimes reach the 100% without problems

I think that ins’t the media (this media works greats in other burnings) … but i try several things and nothing help me :frowning:

It’s a hardware problem? If I use Liggy and Dee firmware may resolve this problem?

Out of 3 burns… 2 appears this error and 1 the writing is perfect!

PS.: Is not the heat, i tested this too ^^’
