My buddy's hard drive on his 12" PowerBook has recently died. I'm trying to recommend him a good replacement on NewEgg.com. I notice on Apple's website that Ultra ATA-100 is listed as the interface.
PowerBook G4 (12-inch 1.5GHz) - Technical Specifications
However, on NewEgg they only sell 2.5" drives with the following interfaces:
ATA-6
SATA 3.0Gb/s
Serial ATA150
Would any of these work on his PowerBook?
