I bought one of the Pacific Digital 8x8x32 drives a few months ago.
The box said 8x8x24 on the outside and I had bought it because Pacific Digital had been putting Yamaha 8x8x24 drives (4 MB buffer) in those boxes.
It was a Samsung SW-408B (2 MB buffer) inside the box I bought.
The drive works all right but I had to get the latest updates to Easy CD Creator 4.02 and Nero 5.0.x at the time to get any CD burning software to recognize the drive.
I still cannot get CDRWin 3.8d or CDRWin 4.0a to recognize the drive, which annoys me.
