Transferring everything from one HDD to another one

[theguymadmax]

So I’m guessing you don’t have access to an external dual-bay hard drive docking station.

Steps I would take:
Remove the 1TB and add in the 4TB. Then copy over the data from the 2TB to the 4TB  (see below options).
Remove the 4TB and add back in the 1TB.
Remove the 2TB and add in the 4TB

Copy options:

1. rsync (cloning specific files or directories)

Code:

sudo rsync -avx /source/ /destination/

2. Copy folders using the local file manager

3. dd (cloning whole disk)

Code:

sudo dd if=/dev/sda of=/dev/sdb bs=4M status=progress

adjust adjust as needed
if=/dev/sda = source drive
of=/dev/sdb = destination drive

4.clonezilla (tool for cloning)

Code:

sudo apt update
sudo apt install clonezilla
