iBook G4 1.2. After a few minutes on the apple timer screen all we can get is a blue screen sometimes. Harddrive OK when opened in target mode and has been erased and 10.2 successfully reloaded. Does anyone know what the problem might be. Thanks Stephen


iBook, Mac OS X (10.2.x)

    What does Disk Utility say about the S.M.A.R.T. status of the drive?

     

    It does sound like hard drive problems.

    Hi Ronda,

    Thanks for your help.

    We cannot start the iBook from a 10.2 OSX disk because the drive does not seem to work properly. When running disk utility from a iMac Dome G4 (10.3) we find that it verifies that the HFSplus drive in the ibook seems to be OK. I do not know how to find out the smart status (do we need to boot from e.g. a 10.6 OSX disk ?).

    Thanks for any suggestions

    Will it boot in Safe Mode?

    You can view SMART status using the Get Info menu item in Disk Utility but sometimes it doesn't work for external drives (I don't know if a drive in another computer is considered external in this regard).

     

    When you erased the drive did you try writing zeros once in security options?  This kind of stress tests the drive and will force it to have a look at all sectors rather than just saying it removed all reference to the files so the drive is fit and ready for use.

    It won't work when connected in FireWire Target Disk Mode because FireWire disks are not supported.

     

    I haven't tried it via Ethernet.

     

    Ben + Steve,

     

    On one of the times when it will start up for you, check out the S.M.A.R.T. status in Disk Utility on the hard drive. (Applications > Utilities > Disk Utility; click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane.)

    Hi Limnos, Hi Ronda,

    We managed to see that the drive is "not supported" for SMART - (translated from the german - its a german system).  We can start the computer from an external drive and everything seems to work using the external drive - and we can plug in external monitors etc so ports are working. Disk utility thinks that the internal hardrive is OK so I wonder if its a communication problem between the OS on the drive and the rest of the computer ? (not that I understand how this can occur !).

    Thanks

    Stephen
