Verify Disk Problems

[jarrodius]

I keep getting this message when I try to Verify Disk:

"Checking Extents Overflow file.
Checking Catalog file.
Illegal name
Illegal name
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Checking volume information.
The volume Macintosh HD needs to be repaired.

Error: The underlying task reported failure on exit


1 HFS volume checked

"
It won't let me repair. Can you tell me what this all means?

It means you either need to start from the OSX discs, use Disk Utility and repair the disk ASAP, or use fsck if you can't find the discs.
