Issues with gsa-4082b... SOS!

yo. um, having major problems with this accursed drive: i can’t burn proper dreamcast images (since it apparently can’t multisession properly) and neither nero nor cdrwin recognize it. i tried different stuff: burnin’ the same image with both alcohol and discjuggler, tried converting it to nrg just to realize nero won’t like this burner… firmware’s up to date, and i’m lost. any help’s welcome.
