I wanted to send a quick message to resolve this thread. With the help of a friend, I was able to recover the data in question. Since the file was significantly smaller than the ZFS block size, and compression was not enabled (or at least was not enabled at the time the file was written), we were able to read each ZFS block and see if it contained the string in question. I'm happy to say our efforts were successful. My friend wrote a nice little c++ program to do this and posted it here: http://www.aronnax.net/node/20 --Greg
