dd is deprecated? I'm surprised. I use it all the time. It's great when
a blocksize of 512 is too slow, like for large files onto slow backup
disks or network transfers, I might use dd bs=10240 or some such thing.
I suppose the block size on Linux might be bigger these days, but the
command is still standard.
