    My little external USB hard drive has started having problems.
    Although it appears in the Disk Utility app, it won't mount.

    When I try and verify or repair it, I get the following error:

    Code:
    Verify and Repair volume “Little Disc”
    Checking Non-journaled HFS Plus volume.
    Invalid node structure
    Invalid B-tree node size
    Invalid node structure
    Invalid B-tree node size
    Volume check failed.
    
    Error: Filesystem verify or repair failed.
    Is there anything I can do to try and repair it, it is an erase my only option?

    Thanks all!

    You could try a third-party utility like TechTool Pro. If the data on your drive is unimportant/backed up and don't feel like shelling out $100, yeah, a format is prettymuch your only option.
