yes, i'm sure , i looked in nero cd dvd speed under the disc info tab.
And now, i've noticed something, while burning CD. i select burning speed 32x. if drive start burning, it does this at 16x. after approximately 90 seconds the drive spins up more and continues burning at 24x. Before end of burning the drive spins up more again and continues at 32x. Is this normal? This occurred, when i put my drive into external enclosure and connected this to USB 2.0. when my drive was internally installed in PC, i didn't noticed anything like this. Now i can't try the drive in PC again because i have laptop.
