Corrupted file recovery

[Aditya Talwar]

This is urgent and for a friend of mine who cannot access the net.  His
problem is that, he would like to know of a utility or a method to recover
files whose directory nodes have been corrupted.  After doing a fsck, the
lost+found dir was cleared, but he his certain that the files are
exsisting in the underlying directory.  Infact he managed to find out that
the track containing the directory information has been corrupted. There
installation uses SunOS 4.0.3.  All urgent mails will be appreciated.

Thanks
