UNdeleting files

[Suresh B Peram]

Hi,


   I have lost a whole directory containing
   important information while running a shell-script
   which deleted it.  We have a SUN OS 4.0.3 here running
   on a sparc server.  The entire disk was immediatly
   unmounted and has been left unchanged.  I wish to
   recover these files as soon as possible.  Does
   anybody know the best way to proceed ? Unfortunately,
   I do not have the source code  of Unix.

   Any help will be greatly appreciated.

Suresh
