form of '-from:"\\.\PhysicalDriveX"', wherein X belongs [0..9].
-todisk: - specify the source disk number. '-todisk:X' is a shortened form
of '-to:"\\.\PhysicalDriveX"', wherein X belongs [0..9].

Recognized size representaion for '-sector', '-block' and '-maxbuf' options:
Decimal digital with suffix 'm' or 'mb' (case-insensitive):
recognized as megabytes.
Decimal digital with suffix 'k' or 'kb' (case-insensitive):
recognized as kilobytes.
Decimal digital with no or others suffix: recognized as bytes.

Identify the device name:
On Windows platform, The storage device number could be identified by using
the Disk Manager (right click 'My Computer' and select 'Management').
On linux and other unix like platforms, the device can be found in the /dev
folder.
