    my hard drive crashed and i took it to apple and they said it was dead. i got a new Western Digital 500Gb hard drive and tried to install it myself but my computer could not see the hard drive in disc utility etc. so i plugged it in externally using a SATA enclosure. i was able to successfully install mac osx onto my new hard drive and boot up my computer using the hard drive externally but as soon as i put the hard drive back into my computer, it is un able to boot up. I can see the hard drive when i turn on the computer and hold option but when i click on the hard drive it fails to boot up.

    any suggestions on how i could fix this problem?

    Did you format the drive as an HSF+ partition before trying to install OS X? You need to do that otherwise you won't see the disk. All WD drives are NFTS formatted for Windows so like I said, you need to format into HSF+ Journaled.

    yes i formatted the drive properly and i have installed OS and it works if it is plugged in through USB using a SATA enclosure. but when i put the hard drive back into the computer it does not work.

    If there is another internal port for connecting hard drives, try connecting it to that. Maybe you have a bad SATA port.

    Everything is fixed.
    I took it to apple and it was the SATA cable inside that was faulty. Best part is they replaced it for free. Thanks everyone for you help

    Thanks for the update. :cool:

    One thing, with this faulted SATA cable maybe you older drive wasn't bad. Did you ever get it back? If you did get something like the Hard Drive Dock or Univeral Drive and check that hard drive.
