    I want to upgrade to a larger drive so I purchased a new sata 500 gb drive and external case it will not show up either on the desktop or in disk utilities. I have tried two cases two cables and even bought another drive and no luck. I am runnin 10.5.8 system and my time machine external drive shows up fine any idea what Im missing here. I also tried the drive on my sons macbook pro running 10.8.5 no luck Ive tried restarting and even booted with a 10.5 install disk in the cd drive still doesnt show. I have clowned my hard drive with carbon copy cloner on my time machine drive but am reluctant to put the new drive in my machine and try that.

    Two sets of drives, enclosures, and cables fail to been seen by both your machine and your son's machine ...on USB2 or FW ports?

    If USB 2, can you plug them into a friends's computer just to see if the machine sees anything? If FW you will need to try another Mac that has FW ports.

    What model?

    Two computers failing to detect the drive could mean several things including:

    • The drive is faulty
    • The drive's housing electronics are faulty
    • It's a 3.5" drive that requires a power supply that's not plugged in or isn't working properly
