It has code that you enter the block number and it will report to you which part of the file system that block is in, such as cylinder group, file data, etc. It doesn't dump the data blocks, but it does dump files, and w/o much modification can be made to dump this. It's written in C, and will effeciently use a raw device as I added my own caching structure to it. ffsrecov was a util that was hacked together to get data out of a disk that inode 2 got completely corrupted. (and I did get the data I needed off the disk). -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."Received on Sat Feb 28 2004 - 07:03:37 UTC
