I get the message "can't repair because the disk is locked" (or some variation of that) when trying to repair a disk using Disk Utility, Drive Genius, DiskWarrior. Also get a similar message when I try to format (partition) the same drive with Disk Utility. What does it mean that the disk is locked? How do I unlock it?
