An Enhanced version of gnu dd with features useful for forensics and security. Key features include on-the-fly hashing, status output and faster disk wiping.
Sorry for my lack of experience with sourceforge. I wanted to report a bug with dcfldd, but can't see where/how to do it. The bug is that apparently dcfldd ignores the count= option. I tried copying part of a large file to another file, intending to limit the number of blocks copied. dcfldd just kept right on going after passing the number of blocks I had specified in the count= option.
