I highly doubt it, what errors are you getting when running the fsck ? are u getting errors at all? does disk util throw up errors?
Is it possible you MOVED the applications out the app folder by mistake?
Fsck as well as disc util told me it can't repair the HDD
well fcp stopped responding after rendering then suddenly when i restarted half my apps are gone (all the apps from a to f are present) but the rest are just GONE.
I am really getting sick and tired now, i need this mac to work.
