Is there a website that tells you what type of drive is inside of all the portable drives on the market? What I am trying to do is swap out the drive from my 12" 1.33mhz Powerbook into the external enclosure and take the new drive out of the enclosure and put it into the powerbook. That being said, I need a 2.5" Ultra/100 IDE drive. Only problem is...I can't tell what's inside most of these drives. I suspect they are almost all SATA drives, but thought there might be one or two out there that are Ultra/100 IDE's. Thanks.
