When I try to copy files to my hd, it wasn't working, so I went to disk utility to have a look. It said that my 320 gb hd was a 128, and it doesn't show the last partition. So verified the disk and here is what it did.

Code:

Verifying volume “Mac OS X”

Performing live verification.
Checking Journaled HFS Plus volume.
Invalid number of allocation blocks
Volume check failed.
Error: Filesystem verify or repair failed.

And if I use my dvd to check it, it says its fine. So I ran a repair from it anyways, but it didn't help. What do I need to do?

Come on guys. You all are a great forum, and I really need the help.
