[QUOTE="ian_anthony, post: 738288, member: 70126"] I have a MacBook which came up with a flashing folder with a question mark last night when I started it. I went into disk utility and located my HD after starting the MacBook using the Install CD. However the HD: Disk0s2 was grayed out. I tried repairing the disk but every time I did this, I got a message saying "Invalid B-Tree Node Size". I also tried running fsck as a single user on the drive and got the same message. Now when I go into disk utility, I don't even see my drive anymore. The only thing I see there is the OS X Install Disc. I don't have any backups of my drive. I've also read that disk warrior may be an option. However, before I went down that route, I wanted to find out if there are any suggestions at all. I would very much appreciate any help that anyone can provide. [/QUOTE]
