The 106S/AO6S/116S are ATA66 drives - You need to use an ATA66/100 cable if you are using it with an ATA66/100/133 controller or you will have problems. Because it is ATA66, however, I have installed mine as master on the same channel as my 16X CD-RW and it does flawless copies without resorting to burnproof - It just keeps ahead of the CD writer at full 16x burn. Most CD/DVD-ROMs can't do that on a single channel.
I thought a thought, but the thought I thought wasn't the thought I thought I had thought.
