    Macbook, 2 1/2 yrs old, running Lion OS. Suddenly sluggish, did single user start, got this message

    ** checking catalog file
    disk 0s2: I/O error
    Invalid node structure
    ** The volume HVB could not be verified completely.
    /dev/rdisk 0s2 (hfs) EXITED WITH SIGNAL 8

    on rebooting got apple logo and then progress bar that got perhaps 2% along, then shut down. This must mean something to someone other than expense for me.

    Backed up on time machine.

    Any help gratefully received

    OP, I updated the title to make it a bit more descriptive.
