OSX Lion invalid sibling link
Morning everyone, I've just being handed a MacBook pro with Lion on it. Apparently it was working and now it hangs at boot with the spinning wheel. I booted into the recovery partition and ran disk utility which came back saying the hard drive had an invalid sibling link and that I should backup what I can and reinstall the os.
Question, how do I backup what I can? I can't mount the drive in Windows or OSX although I have used testdisk to do a recovery on it which has copied everything with a random numerical name (not really helpful with thousands of files recovered) was wondering if any one knew of a way to repair the drive or recover the data?
I did see disk warrior but the user is reluctant to purchase it at the moment. Any help as always is appreciated.
