I used Carbon Copy Cloner to clone FCP project and media files to a new GTech Mac formated 4TB drive from a source OWC Mercury Elite Pro 4TB drive using MAcBook Pro w OSX 10.67. It seemed to work after 40 hours of copying but apparently only because both drives were still connected to the computer. When connected solo, the cloned GTech is not readable nor will initialize. Disk Utility not read it.
Also now the master source drive does not allow files to be changed and saved, deleted or any thing copied onto the drive. Error code -50 pops up. The drive has Read Write permissions. I can only open files read them and render in FCP.
Is there a way to fix this clone or wipe it to start over? If the destination disk is not even readable how can I make a working clone for my editor to use?
