Invalid node structure or key lenght
Hello
My iMac was OK but ...
- once I switched to MacOS Lion, i was obliged to reformat HDD before installation because of "invalid node structure" found ...
--> Everything was OK ... Until now :
Today, my widgets did not work...
- I check Library/widget folder : the finder froze during 30sec and show me a Zero kB folder ...
- Disk Utility asked me to reboot because of Hard drive issues that need to be repaired
- Reboot via Lion "Recovery" disk : Disk Utility has issue with "invalid node structure" and can not go further ...
- I relaunched Disk Utilty repair : it then have an "invalid key length" error and can not proceed repair ...
--> what can I do ? Any additional checks ?
--> is my HDD dead ? My iMac is only 9months old !!
Thanks in advance ...
