Diskutility cannot Repari Disk.

I am Running OS X 10.5.1 On a Macbook Pro 3Gigs of RAM C2D. Lately I have noticed things were no longer running snappy and became down right slow and choppy. Like my Disk was bad. So I did a Diskutility Verify-Disk and I got the following output.

Verifying volume “Macintosh HD”

Performing live verification.

I do not have a Repair Option.... Is there any way to repair this.... Rebooting into Single User Mode and FSCK (if so how do you get into Single User Mode) or something to run in the terminal. Or is the Disk Bad or the File System is just screwed up.

Ok I think I answered my own question Here was the Fix...

Shutdown Computer

Power back hold down Command S

run fsck -fy

then reboot again and things seems to be fix...

In order to repair the disk, you must be booted from another source...generally your install disc.

Well in my case I didn't need to do that. If the disk on the average is OK. and you can Boot in Single User Mode the Disk is mounted as Read Only allowing you to fix the file system. This is the same for all Unix systems.

How do I enter fsck -fy? Where do I go to enter this in so the disk checking can begin?

Hold down CMD-S at startup. You will see white text on a black screen. Wait until the prompt appears (like /dev/joe or something like that) and enter the text. then press enter.

While Disk Utility is at it - you might want to verify / repair the "Dictionary Partition" of your hard drive. That appears to be corrupt, too.

On a serious note - hope you fix it.
