My hard drive died in my MBP a few days ago, so I went out and bought a new Western Digital 2.5" Scorpio 320 GB HD from Fry's. It even said on the side of the box it supported the Mac OS. So I install it, I install Mac OS X, and was then at the point were you are asked to Migrate any old data. I chose yes, intending to migrate my user account from my External Hard Drive. The HDD was not detected, so I said "Oh, Well" and hit Go Back. The pinwheel replaced the mouse and just sat there spinning. I let it sit for about a minute and a half before doing a Hard Shutdown. I rebooted the computer and watched the Apple Welcome Video for the 2nd time, only this time the video froze when the big X started flipping onto the screen. The audio continued, but the video was frozen. The computer seemed unresponsive. I let it sit for a minute before saying ****, and restarted for the third time. This time I get a kernel panic while the apple logo is on the white screen with the loading circle under it. Great. Then I booted from my External Hard Drive to see if the hard drive was detected in Mac OS X. It was. At this point, I should have ran Disk Warrior or something, but I didn't. I ran a Verify from Disk Utility, which reported the drive to be a green 'OK'. I ran a Check Permissions, which froze Disk Utility half way through the test. I rebooted one more time, and now the disk is gone from the desktop, too. I am at a loss as to what I can do at this point. When the hard drive is not detected in any of my diagnostic programs, I can't get much accomplished. I can hear the HD running, so I know it has power. I thought maybe I should unplug it from the logic board, and plug it back in. But I did not have much faith that it would solve the problem, so I have not done that yet. I wish I did not have the only Macbook to date that does not have a conveniently accessible hard drive next to the battery. I have to take the damn top case off every time I want to do anything to the hard drive. Any suggestions? I find it hard to believe the hard drive could possibly be completely useless now, but I have no idea.
