Clonezilla

Create a clonezilla usb drive

Downloaded clonezilla-live-2.7.3-19-amd64.iso
Used rufus-3.4.exe to write the image to my usb stick.

Clone

Attached new disk (500GB WD5003AZEX) to guidedogh SATA2-#1 port.
Boot with clonezilla live via usb, 
  device-to-device option
  Beginner mode
  local_disk to local_disk clone
  sfck (skip checking sectors - we know disk is good).

  Test the new disk by boot it up.
  The labeled and package the disk. - will use it as a bigdog replacement.

Bigdogh returned to its orginal setup.

2021/12 - Replaced the bigdog disk
Used the disk to replace bigdog's disk (seeing sector errors) on 2021-12-17.
Setup the hostname, and IP as bigdog:
   1. boot up the guidedogh disk.
   2. set network configuration to bigdog before shutting down:
      /etc/sysconfig/network
      /etc/sysconfig/network-scripts/ifcfg-eth0
      /etc/sysconfig/network-scripts/ifcfg-eth0:1

2021-12-17 - created a new guidedogh clone as a shelf spare.
