Ps3 hard drive, into a computer, problem?

okay, so my playstation just died, so i removed its hard drive and put it into my computer. all the wires hocked up fine. i turned it on and vista automatically installed the driver software. i restarted the computer. The computer seems to be able to detect the hard drive no problem, but i cant access any of the files. i checked bios, i fiddled about in device manager. but nothing ( i even Ran the computer in Lunix ). does anybody have any other suggestions.
