Yep...... don't have to fool with an oddball program (dcfldd). So if
you're dd'ing a disk, you need to:
1. dd the source to the destination.
2. md5sum the source
3. md5sum the destination.
(3 passes on a big disk(s) takes a long time.)
But if you use dcfldd instead of dd for the copy, then you'll get both
the copy and the md5 on the first pass.
1. dcfldd the source to the destination; get the md5.
2. md5sum the destination.
And if you use dcfldd instead of md5sum to run the destination hash, you
can specify a large (e.g. 4 gig) blocksize - cutting back on disk I/O,
wear and tear, and time required to hash the destination.
