I have a G4 flat-screen iMac running Panther. Recently it froze completely, and on trying to restart it I got a plain grey screen with the folder icon and flashing question mark. I first tried booting from the install disk and using Disk Utility, however when I select the drive all the options in Disk Utility are greyed out, and it doesn't appear possible to do anything. I was then advised to obtain a copy of DiskWarrior. This I did, and on running it got the following message: "DW has successfully built a new directory. The new directory cannot replace the original directory due to a Mac OS services failure - try rebuilding again". I've done it three times with the same result. I've got some photos on this drive that I really want to save if at all possible (I know, they should have been backed up, but they weren't!) I'm wondering whether if I were to attempt to re-install OSX it would correct the problem sufficiently to allow DW to finish the job. If I do this though, do I run the risk of losing the possibility of recovering the photos?
