Invalid node structure, cannot repair disk, VERY valueable data... HELP!
Ahhh, my father is a film maker and i am staying with him for a few weeks.
He shutdown his computer because there was a thunder storm. After the storm turned it back on and cannot access his external firewire drive (western digital 300gb) he has tried repair disk in disk utilities and it says invalid node structure there for it cant repair.
This disk has very impotant data as my father is a film maker and it has alot of his work on it.
Please, is there anything we can do to fix this disk?
He is running powerbook G4 1.5ghz on OS X 10.4.11

he is now copying the recoverable stuff.
Dont worry about this topic unless you have a good fix which will fix the drive.
Thanks if anyone looked.
If you just "turn off" an electronic device, most of the time it's still On, and you don't even know it. If the computer is plugged directly into the wall, you're lucky it's still alive. Secondly, if it isn't, not all surge suppressors are the same. I spent 80 bucks on the one I use now, and I'm about to do it again because the warranty is about to go out.
Even your father should know to detach external drives from their host when there is a storm. That's just common storm-chaser knowledge and the Weather Channel goes on about it every other day.
Turns out disk warrior managed to recover ALL the data by rebuilding the directory so we are both relieved.
Thank you for your help.
Reverocks, here is the strategy your father should follow:
- Use the computer for original material
- Make daily backups (probably incremental) to an external device. The external device should be for data backup ONLY
- power-off and unplug the external device when not in use
- if the backed up data is critical/valuable, consider a second backup device for redundancy. Perhaps perform full backups to the second backup device on a weekly basis. Store the the redundant (second) backup device at a physically remote location, such as your father's place of work.
- any automation that stores valuable data should be connected through a high quality UPS. Two good manufacturers are Tripp Lite and APC. Do NOT shop by price; DO shop by brand and power rating.
There are several excellent backup utilities available, one of which is Acronis. (don't know about Apple compatible/recommended software)
Software security can be had relatively inexpensively. There is no reason why your father should ever have a data loss crisis again. Blunt, but true.
I'll back this up. we use spinrite everyday, and i use it monthly on my computers at home to catch failing drives early. i would HIGHLY recommend everybody have a copy of spinrite to run on their harddrives regularly if you have important data..
