I've been using ddrescue recently - by default it seems to be faster = than plain old regular dd. I assume it must be possible to adjust the parameters (blocksize?) to = speed dd up, but I just want to run the command and not have to bother = tinkering. On dumb blind copies, I'm finding ddrescue about 3x or 4x faster than = dd, I would estimate. Stroller.
