Mac Hard Drive File Read Error

Hey all! I'm currently trying to setup bootcamp for my mac and the first thing I need do is partition the hard drive. However, when I go to do this it doesn't allow me to "repair disk" because the verified disk has an error. This is the error report that comes up:

Verifying volume “Hard Disk”

Performing live verification.
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.

Checking volume information.
Invalid volume file count
(It should be 670295 instead of 670296)
Invalid volume directory count
(It should be 184135 instead of 184134)
The volume Hard Disk needs to be repaired.

Error: Filesystem verify or repair failed.

Any idea on how to fix this? I reallllly want to use windows! Thanks!

How big is the Hard Drive and how much free space do you have?

To charta:

You can't repair the hard drive while it's mounted.

In order to repair the volume, reboot the machine using your install DVD. Cancel out the install routine and select "Utilities" "Disk Utilities" from the top menu. Then select the "First Aid" tab. Run "Verify" and "Repair". Keep running it until all errors are cleared.

Reboot back to OS X and run the Boot Camp assistant again.

Regards.

Harddrive space

I have a 160 GB HD and i have 143 GB free space.
