Hi All, I have a 1ghz G4 AGP with 768mb of ram running 10.4.3, I was using tech tools 4 and ran a check on directory structure on my second hard drive. It came back and said that it needed a few repairs, so I allowed those repairs. Now my hard drive is gone. If I use the apple disk repair utility it sees the hard drive but comes back with the error: Invalid B-tree node size Volume check failed. Error: The underlying task reported failure on exit I have tried to verify and repair with the disk utility, to no avail. Does anyone have any ideas as to how I could access this drive? I have a ton of stuff that I need to get off the drive. Thanks in advance, Bob
