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 ...

iMac Core i3 - 21,5 Inch, Mac OS X (10.6.5), iPhone 4 4.2.1

Quick answer to my old topic :

Hard Disk was faulty : iMac has been repaired at Apple store (hopefully, it was still under warranty-period) and changed my Hard Disk.

Thanks to Time Machine : I had no impact on any documents and everything is fine since then (more than 1year)

Hope this might help ...
