It's been almost over 6 month, I didn't run "Disk Utility" on my Early 2006 Tiger MacBook. As of tonight, I I just run "Verify Disk" .... FAILED to complete. So it won't let me click "Repair Disk" (inactive; no way to click). That means I have to use my Tiger DVD boot up from superdrive! Problem is my superdrive has been not responding at all for a couple of month. Since I don't use it at all, I didn't care. ... but now I need to run my Tiger original DVD What should I do? Please let me know how to proceed to repair my HD without using superdrive as it is not working. Any alternative?
