Help! My Startup disk need to be REPAIRed. The Disk Utility app confirmed it: Invalid volume file count Invalid volume directory count The volume SSD256 was found corrupt and needs to be repaired. Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk. I, however, only have a wireless keyboard. Other than looking for a friend who can lend me a wired keyboard for an hour, do I have any other options?
