Unfortunately that program is also on the crashed disk :-O Since you are on 4.8-R you can take a look at ffsrecov. I wrote this program a while back to try to recover data... This program might be able to help you since it will only read minimal amounts of data.. it also will scan for superblocks and report where it believes the begining of the FS is... it also has a mode where you can give it a block number and it will tell you what part of the fs the block is allocated to, be it inode, or data, or free... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
