A family member has an old G4 iBook running 10.4.11 (Tiger). Recently, it has refused to boot up past the first screen (with spinning gear). I ran disk utility off of the Tiger installation cd and it failed to repair the drive and it gave the message "Reserved fields in catalog record have incorrect data". I started the iBook in target mode and connected it to another Mac. The drive mounted on my desktop and would open up but would give me the spinning beach ball when I attempted to open things. Doing a Google search, a few people recommended Diskwarrior to recover the drive. Does anyone have an opinion on this program or are there better recovery programs ? I'm taking my family member out to shop for a new computer (he wants another Mac) so my goal is just to recover what files I can from the iBook.
