=====Cloning a HDD=====
1. Boot from any Linux Live CD/ USB key
2. Intall gddrescue
sudo apt install gddrescue
3. Open gparted, check the name of the input and output drives (sda, sdb, sdc, etc)
4. Once you know, the only thing you need to do is type in the terminal (replace sdX and sdY by the input and output drive, respectively):
sudo ddrescue -f /dev/sdX /dev/sdY /home/logl.log
5. Done. Safer and faster than dd command.

Best i found is using a clonezilla live usb key. Use Etcher to burn the iso.
