Has anyone had a problem with a Macbook pro not starting after this happened?

Question

I have a Macbook Pro computer and I was using the disc utility software. I let it run all night to perform its duties. I was able to do the verify permissions portion and the repair permissions portion of the disc utility. When I got up this morning to verify the disc, it stopped about 2 minutes into it and said that there was an error. Didn't tell me what the error was except that the disc verify failed. Same with the repair disc feature failed as well. After I given up on using the repair action I then tried to restart the computer and go on about my business when I find I can't use it. It will start up like normal to the point after the grey apple appears, after that it shuts off. Tried it several times now and get the same result, computer comes on, grey apple appears and then it goes down. Have any ideas on how to get it working again? Thanx.

Answer 1

Looks like drive corruption, possibly caused by a failing drive. Two utilities to look up would be Techtool Pro and Diskwarrior. TTP does some repair, SMART tests, a complete surface scan, and more to tell if your drive is failing. Diskwarrior is f**king magic at cleaning up corruption and errors, far more than Disk Utility in OS X.



But first, boot from the OS disc that came with your Mac and hold down the D key at the boot chime. This will boot it into a diagnostic. It's not terribly comprehensive, but if it finds a problem then it's shop time.

Answer 2

The "Invalid Node Structure" error is a an error in your Mac OS X volume which occurs when

the cataloging system in the Mac OS X directory, which keeps track of all data your hard drive is damaged and irretrievable.



As a result, what you will need to do is look into 3rd party Mac diagnostic and repair utility software such as:



• Disk Warrior 4.2 (http://www.alsoft.com)

• Tech Tools Pro v.5.0.6 (http://www.micromat.com)

If you do decide to use one of these great Mac utilities to repair and rebuilt the damaged OS directory, and are still unable to rebuild the directory, and get your hard drive back to booting to the Mac OS X volume as it used to, then you may want to consider this option below:



• If you have another Mac with an external hard connected and, you can perform a Target Disk Mode procedure (http://support.apple.com/kb/HT1661).



• With this process in place you can attempt retrieve your Home Folders (which contain all the data for your user account) and copy that over to the external hard drive connected to the other Mac.



Otherwise, if that hard drive does not respond to any of these processes, then it will be time to take your Macbook Pro in for service at an Apple retail store Genius bar or local Apple authorized service center.



Just for your reference, I have taken the liberty to provide the store locator links to your local Apple Retail store as well as a general store locater for locating any local Apple Authorized Service center in your area.

Answer 3

Your Hard Drive has failed. If it's still under warranty you can get it replaced, but any data that's not backed up is pretty much gone.



This has nothing at all to do with the Software Drivers and everything to do with the actual Hardware.



Even if you could get this drive running again, I wouldn't trust it anymore. Take it to the Apple Store or call Apple and get a replacement drive.

Answer 4

It would seem your Mac has forgotten how to read the disc. Your best bet is to take it to an apple shop and explain that you computer can nolonger read its drivers. This is their fault and they should fix it.

Answer 5

Stop in the Apple Store for a quick [hopefully] fix. It's free, you're under warranty.

Answer 6

Have you tried checking to see if the disk is partitioned with an accessible volume in Disk Utility?
