Disk Utility CANT repair disk

probably goes without saying that anything on that drive should be backed up asap and very, very frequently from this point on.

That's certainly never a good sign. Is it making any noises? Clicking, grinding, anything like that?

 

are you running disk utility from within your startup disk? If so, you shouldn't. Run the Disk Utility from the OS X Install Disc. See if that works.

 

Boot from the install disc and try running it there.

 

As the previous post says, run the utility from the install disk:

Put the CD in
Turn your computer off
Hold down the C key and turn the computer on (hold the key until the Apple comes up)
Select your language
From the Utilities menu select Disk Utility
Select your dive (not the partition) from DU
Click Repair

I had HD problems which I could not fix. Thanks to BenjaminDaines, I learned that I had to run the utility from the disk instead of from my applications folder and it worked!

This same thing happened to me about 2 hours ago, I was able to boot off my iPod Mac OS X install and backup the disk and had to format the HDD.

 

Did this error come about while using boot camp.

 

Get Disk Warrior. It's 1000x better than Apple's Disk Utility at repairing problems that aren't actual hardware failures. It's saved me a number of times over the years when Disk Utility failed.

 

Ditto. From my experience "Invalid File Count" is beyond Disk Utility to repair.

 

Had a problem in the same order. Turned out that the HD needed to be replaced. The MP was brand spanking new, as in 2 weeks old. It spend a good 2 weeks at the repair center when it finally came home.
