My macbook greeted me with the gray screen and folder with question mark this morning - I've tried everything listed on the Apple website for this issue, I've tried running the DiskUtility (although I'm getting an "error no valid packages" message) and I've tried running DiskWarrior. DiskUtility sees the harddrive - DiskWarrior does not. The hard drive only "clicks" 3 times at bootup, but it stops immediately after. Can I conclude that the hard drive is not entirely defective that it's just a bad header, or boot sequence or whatever "fixable, I won't lose all my data" error? My other question is that if I can see the hard drive in DiskUtility, is it possible to create an image of it that I could say extract the data from on another Mac? Thanks.
