Thanks for the reply! Well, ive tried to open the case, and i couldnt see the laser...the case was hard to open in the inside...and i ended breaking it! So, ive throwed it.
So, now i've got 3 possibilities. Please recommend me what's better:
a) New DVD burner (ultra dma2 = 33MB/s) + old CD-RW (multiple word dma 2)
b) New DVD burner (ultra DMA 2) + CD-ROM (ultra DMA 2)
c) Only DVD burner
