#  Well, If you are desparate and have a larger extra disk you can throw
#  on the the system, you can dd the raw partition to files on a file
#  system on the spare disk. It more manageable if it is split in to
#  uniform size chunks (< 10 mb).
#  
#  You sequentially run the dd till you run out of chunks.
#  
#     dd if=/dev/rsd01g of=/spare/part1 bs=8192 count=1024
#     dd if=/dev/rsd01g of=/spare/part2 bs=8192 count=1024 skip=1024
#     dd if=/dev/rsd01g of=/spare/part3 bs=8192 count-1024 skip=2048
#  
#  You *MUST* do this before much disk writing happens on this file system
#  because the disk blocks that your data resides on are fair game for
#  reuse when blocks get allocated to newly created and growing files. Once
#  you have all the data in chunks you can use the strings command to look
#  for familiar patterns of data (i.e. 'strings part1 | grep 
#  some_pattern')
#  if the lost file is a text file. Once it is ascertained wich chunk
#  the lost file is in, you can use the old familiar hammer (vi) and
#  save the lost portion to a file.
#  
#  If you cant scrounge enough disk space you can do it kind of 
#  piece meal.
#  Save a chunk to a different file system, scan it for your lost data,
#  toss it if it doesn't have it, repeat for next chunk.
