Hi Everyone, My computer's hard drive is on the fritz. I keep getting a gray boot screen with a status bar that never loads. This has happened a few times in the past, and I usually solve the problem by booting from the original install DVD and repairing the drive in disk utility. This time, I'm getting a "invalid sibling" message in Disk Utility. The last time I got this message, I was able to follow the instructions on this article from Macworld: http://hints.macworld.com/article.php?story=20070204093925888. I tried the fsck_hsf -r command on the drive to rebuild the catalog B-Tree. Like I said, this usually works really well. But this time, I am getting an error message in the terminal that says "the volume Macintosh HD could not be repaired." Does anyone have any suggestions? I know I need to replace the disk soon, but I'd rather not right now.
