Repair macbook hard disk
From Finninday
A late 2007 Macbook refuses to boot.
Holding down Command-S brings up single user mode.
Running fsck -fy doesn't fix it, but yields the error "The volume Macintosh HD could not be repaired".
Running fsck -d to get debug info gives more detail:
- root device is /dev/rdisk0s2
- journal replayed successfully or journal was empty
- Index key doesn't match first node key
- Invalid index key (4, 35529)
- rebuilding catalog b-tree
- hfs_UNswap_BTNode: invalid node height (1)
- volume type is pure HFS+
On a parallel track, trying to create a bootable USB stick to use linux tools to troubleshoot the corrupt root filesystem.
