    some how i managed to completely ruin my sharing permissions on my computer.

    computer number 1 (my computer) cant access its hard drive - it had a little minus sign on the folder - when i restarted it i only get to a blue screen.

    i tried this...

    and now i get a grey screen, i've tried putting the OS X disc in and it doesnt pick it up.

    the weird thing is i can access my hard drive through my other computer (computer number 2) when comp 1 is sitting on the grey screen.

    is there a way i can change some text file on the hard drive to change all the sharing permissions or something???

    are you sure it has something to do with permisions?

    If so , I can't help you. but once I also hung at the blue screen. the solution was to take the leopard disk, boot it and use the EHBO feature from the disc utility, maybe you coud try that?

    Can you run the hardware diagnostic test when it boots by pressing and holding the D key?

    If you could boot from the Install DVD, you have to go into Disk Utility and try doing a Repair Disk Permissions.

    fredltd, what do you mean by saying that you have access to your HD through computer #2 ? Is it perhaps possible to use comp. # 2 to change the permissions on comp.#1 HD?
