You can verify your emergency couple episode 6 disk with file command: file : x86 boot sector; partition 1: ID0xc, starthead 130, startsector 8192, 114688 sectors; partition 2: ID0x83, starthead 165, startsector 122880, 6277120 sectors, code offset 0xb8.

You can choose to keep the entire drive updated, or just a subset of files (.g., your home directory).
The essence of the cloning process is copying data from one drive to another.
