Hi all,

When I boot up my PowerBook G4 it freezes. When I boot into single user mode and run fsck -fy I get the following messages:

** /dev/rdisk0s3
** Root file system
** Checking HFS Plus volume
** Checking Extents Overflow file.
** Checking Catalog file.
Missing thread record (id = 72)
Invalid extent entry
(4, 14531)
** Volume check failed.

I do not have Disk Warrior nor the Apple disks with me. Any help you can provide is greatly appreciated. Navigating my disk in single user mode seems to have all my directories etc.


PowerBook G4, Mac OS X (10.4.3), 1.25 GB RAM

    Welcome to Apple Discussions!

    Unfortunately without those tools it may be difficult to recover from your situation. Have you backed up your data?

    I am trying to back up my data now. I only have my FAT32 formated iPod with me and I'm trying to mount it to backup my photos before I reinstall. Unfortunately I do not see my iPod popping up in /dev at all so I cannot even mount it.

    It's a USB connection so I suspect that single user mode doesn't pick it up... Any advice on how to mount a filesystem from my iPod in single user mode is much appreciated.

    What you need is a bootable external hard drive. Or another Mac. USB can't boot. Only Firewire can boot. Copying to a FAT32 drive is not going to necessarily preserve all the filenaming and formats you may need. I'd only copy the information to a Mac HFS+ formatted volume.
