The short of it is. I went into the sharing preferences in 10.5 Leopard and shared the boot drive. I then set the sharing settings to only allow the main user account and removed "administrators" and set the everyone option to read only. After doing so the hard drive turned into a folder with a stop sign on it. Then different programs started freezing and text started becoming garbled on screen. Apparently the sharing settings also effects folder and file permissions. While I thought it was just a separate entry stored by Mac OS X. Anyways I have booted off the install CD to try and repair permissions to no avail. As the boot drive is no longer recognized as one so there is no option to repair permissions. Is there any way to re-bless the System Folder so that repair permissions can be run? Or will I have to reinstall Mac OS X and wait 10+ hours for all the backups to be restored plus time needed to correct settings. If you are wondering why I did this. I was trying to give Windows in Parallels greater access to the files. As it seems to lose the connection to the shared folder screwing up access to my Outlook .pst files. They are stored on the Mac side to guarantee a back up as I am uncertain if the Parallels disk image gets backed up by Time Machine, after the initial backup. In Terminal through the install cd I have tried chown -R root:wheel * chmod -R 755 * to give full access back to root for the entire hard drive but Disk Utility still does not recognize it as a bootable drive to repair permissions on.
