Hard drive correuption?

My Macbook Pro has recently started to slow down, a sign of me possibly needing a new hard drive. I have 35 GB's left on my drive of space, but I recently went to the Disk Utility and verified the disc. After doing that a message came up telling me I needed to repair the disk due to a corrupt file. Hold CMD R while restarting and use Disk Utility. I followed those directions, verified again through it but it came back as OK. I'm not sure what's going on. Can anyone shed some light on my situation?

MacBook Pro, OS X Mountain Lion (10.8.2)

OSX needs breathing room. if 35 GB is less than 15% of the disk, your OSX is having some minor issues keeping its operations straight probably.


You should start freeing space and your Mac will likely speed up some.

You cannot fix an active partition.


When you restarted under the Recovery Partition (a different partition) OSX probably fixed the minor issue as part of housekeeping because it could at that time.


35 / 250 = 14%, which is tight.


You have been running tight for a while, I guess. OSX has been very busy shifting files in the file space. The more room you can give it for at least a while will help.


You can download OmniDiskSweeper from macupdate.com to get a view of all files and their size and location on the disk to help sort through.


But if you have *ANY* doubt about whether or not you can delete a file safely, post back and ask.

Okay, great. I've already downloaded the OmniDiskSweeper app and will try that. After I enter into recovery mode and find nothing wrong I go back to the Utility sweeper and it shows the same corruption file error that I got before I restarted under recovery. I'm not trying to be difficult, I've researched it only and can't seem to find an answer other than possible hard drive failure. Thank you for helping me!

Could be a failing disk. All disk will fail eventually.


Read this for backup methods, especially "clones" which are bootable copies of your system on an externl disk: https://discussions.apple.com/docs/DOC-3045


The clone method would allow you to pull your old disk and install a new one, then "clone back" to your new disk and carry on as if nothing ever happened. Also gives you a chance to upgrade to a 750 GB disk which will feel like a McMansion to you.

Commifreak, yes it came with the computer. It was a refurbished one from Apple, and I don't know exactly how old the harddrive is.


Steve359- $75 for a 500GB hard drive? I can't find one for that price lol. Their more like $260-$500.00 I'll definately back up my system though. Do you have a preference in hard drives or websites to go through?
