Bravo. I'm horrified reading recommendations to use dd for cloning files on storage devices. dd copies fragmented files as is so you are messing new drive for performance issues from the get go.


btw:  you can "practice" dd with a usb stick or two, if you don't care what's on  them.

take an empty usb stick,  copy some stuff on it,  copy that stick with dd to a file,  take the other stick, use dd to copy it on the other.


USB sticks show up as similar devices in/dev   as /dev/sdx where  x is some letter.


Make sure they (the USB sticks) are not mounted,  and do NOT use the other existing device files in /dev,  except for the ones that showed up new and represent the USB stick
