Just thought to add this. I have tried the unix utility 'ncheck' but this takes quite a long time. The system I am using runs veritas and the vxfs file system, so the ncheck utility won't work there, but there is ncheck_vxfs, although it is not installed on this box. Probably never will be either (boss is a twit).

But either way, ncheck is not much more than a glorfied 'find /path -inum <NUM>' as far as this circumstance is concerned.
