    Please can anybody help.
    I am a video editor new to the Mac world having left PC's after yet another failure. I have an iMac i5 with 4Gb RAM, using MAC OS X 10.6.3 (Cannot connect it to the internet due to the our location). I Edit with FCP 7, having though that this would be as good as Adobe Premier (which it is).
    However, i have had a problem with two external USB harddrives, both formatted OS X extended. At different times, one a few months ago, and one today, they have crashed or something, and then a error message saying "The disk you inserted was not readable by this computer appears".
    In DiskUtility, the Samsung G3 Station Media icon is ok, but the partition now is a light grey and says "disk1s1".
    If i click on the information there is very little information, the most noticable feature being that the Mount Point : Not Mounted.
    Is there anyway to get this drive back?

    Try resetting the SMC. Here are some instructions, sometimes this can do the trick with drives that are not detected.

    SMC RESET

    • Shut down the computer.
    • Unplug the computer's power cord and all peripherals.
    • Press and hold the power button for 5 seconds.
    • Release the power button.
    • Attach the computers power cable.
    • Press the power button to turn on the computer.

    If it's listing the volume in it's Linux format (i.e. d0s2, d1s1), that means it no longer recognizes the volume as being formatted properly. This can be due to a number of factors, but suffice it to say that there is no easy way to get the data back.

    You can try booting into single user mode (Command+S at startup) and running fsck from the command line.

    If that doesn't work, you can try a data recovery software like Data Rescue.

    If that fails, you'll need to take it to a data recovery specialist
