So for the last week or so I have found that my TM Backup was backing up pretty slowly but I just thought it was "normal". But today I get a message when I login saying that my TM Backup is damaged and that I have to erase it. So I open up Disk Utility and Verify Disk, it says i Have an "Invalid number of allocation blocks" and "Error: The underlying task reported failure on exit". Any ideas, obviously me last resort is erasing the disk.

PS - I have TechTool Pro 4.6.1 and it says I have an "Invalid Header. (-9007)", maybe that will help in solving this problem.

Thanks in advance,
