    Hi,
    I am posting this because I am in a mess. I have got the message "You need to restart your computer. Hold down..." in my MBA. Having read what have been posted before about this problem, I do not find a proper solution for it. So I have just copied the message I get from the screen after a safe boot op. It says

    disk=0s2: I/O error.
    0 [Level 3] [ReadUID 0] [Facility com.apple.system.fs] [ErrType IO] [ErrNo 5] [IOType Read] [PBlkNum 57424] [LBlkNum 900] [FSLogMsgID 11596090533] [FSLogMsgOrder First]

    What I need to know is if the message declares a hardware problem or a software conflict and, if installing the last Leopard update from my Superdvrive could solve the problem.
    Regards

    I think you should repair permissions. Do that from Disk Utility off of your OS installation disc.

    disk=0s2: I/O error.

    Not that I know a lot but judging by that looks like the HD is broke.

    Start from OS X CD and run disk utility and repair disk for start

    This should help, boot from a Leopard disk and repair from disk utility.
