What filesystem are you using?  Because if it is ext3 then things look
pretty grim.  See this reference:

  http://batleth.sapienti-sat.org/projects/FAQs/ext3-faq.html

  Q: How can I recover (undelete) deleted files from my ext3 partition?
  Actually, you can't! This is what one of the developers, Andreas
  Dilger, said about it:

  In order to ensure that ext3 can safely resume an unlink after a
  crash, it actually zeros out the block pointers in the inode, whereas
  ext2 just marks these blocks as unused in the block bitmaps and marks
  the inode as "deleted" and leaves the block pointers alone.

  Your only hope is to "grep" for parts of your files that have been
  deleted and hope for the best.

Otherwise everything I know about recovering deleted files is here:

  http://www.gnu.org/software/coreutils/faq/#I-used-rm-to-remove-a-file_002e-How-can-I-get-it-back-now_003f

It is a pretty pessimistic view.  I hope others have more optimistic
information for you.

Good luck!
Bob
