Macintosh HD Cannot Be Repaired

Hi Guys, got a major problem here. Did a verify of my start up volume and it came back saying it needed to be repaired. So I inserted my Tiger install disc and from the utilities menu there tried to repair the volume. It came back saying:

"Error: The underlying task reported failure on exit"

The report above this was as follows:

"fsck_hfs(100)malloc: * Deallocation of a pointer not malloced:0xbc000; This could be a double free () or free () called with middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug"

Now I have no idea what all this means only that my volume cannot be repaired. Can anyone help?

Intel iMac Core 2 Extreme 750gig HD 4gig RAM, Mac OS X (10.5.7), Mac Mini G4 1.5ghz OS X Server 1gig RAM

When Disk Utility fails on exit, it means there is an error that it couldn't repair. Usually, people will then turn to Disk Warrior or sometimes TechTool Pro to do the repair. If there is not a hardware problem, in most cases Disk Warrior can fix it. However, if there's an underlying hardware issue, Disk Warrior may not work, in which case you have to replace the hard drive. With that error, I'd go with Disk Warrior for the fix. Their web site is at http://www.alsoft.com/DiskWarrior/index.html or TechTool Pro is at http://www.micromat.com/
