About the dd command:
dd if= of= bs=("USUALLY" some power of 2, not less than 512 bytes(ie, 512, 1024, 2048, 4096, 8192, 16384[/b], but can be ANY reasonable number.) skip= seek= conv=.
Source is the data being read. Target is where the data gets written.
Warning!! If you reverse the source and target, you can wipe out a lot of data. This feature has inspired the nickname "dd" Data Destroyer.
Warning!! Caution should be observed when using dd to duplicate encrypted partitions.
