Hello. I'm having some trouble with my Macbook. It's running on Leopard 10.5.8. I recently tried to partition my hard drive and while doing so it prompted me informing me that there was an 'invalid node structure'. I could then no longer proceed with the partition. I had planned on updating my OS to Snow Leopard. I wanted to partition my internal HD, so I backed up some files on my external HD. I basically wanted my interal HD to run smoothly with a new OS while minimizing the space used. Now I've come across this issue where there is another message being prompted that says, 'invalid sibling links on hard drive'. I found THESE steps on another forum that informed me that this might restore the hard drive back to a readable/functional state but that didn't work either:
(These were the steps I took and nothing happened except another prompt informing me of an 'invalid node structure')
- Boot off the OS X CD (reboot, hold C while booting).
- The installer will load up, go to Utilities in the menu and run Terminal.
- Type df and look for the drive that has your Mac system mounted---you'll have to unmount this. On my MacBook Pro, it was /dev/disk0s2.
- Type umount /dev/disk0s2, replacing disk0s2 with whatever disk your OS lives on.
- Type fsck_hfs -r /dev/disk0s2. If you umounted the wrong thing, it will complain that you can't repair a mounted drive. Go back and umount the right thing and repeat this step.
I then stumbled upon a few different forums mentioning something about Disk Warrior. I was wondering if THAT would resolved this issue. Honestly, I don't really want to spend much money on buying this but I WILL buy a new hard drive if I ABSOLUTELY need to. I was just trying to see if I can troubleshoot this before I decide to throw in the towel and buy a new hard drive or attempt to try out this Disk Warrior thing.
