    My Mac book froze last night needed to use a forced shut down

    When re started got the white screen with the question mark folder.

    Have tried to use the disks and the disk utility tools.

    When trying to repair it states Invalid B-Tree node size

    volume check failed

    Any ideas

    Many thanks

    Disk Utility will not fix every problem. Either use a heavy duty program like Disk Warrior or - if you have a reliable, recent backup - reinitialize the bad drive and restore from your backup. Good luck.
