Steps to upgrade your HDD to an SSD:

- empty the trash
- log out of the graphical interface
- change to a text console (ctrl + alt + F1)
- login with username and sudo password
- switch to root user ($ sudo -i)
- find out how big the home folder is (# du -sh/home/username)
- find all the disks on the machine and their usage (# df -h)
- go to home directory (# cd /home)
- check present working directory (# pwd)
- check what is in directory (# ls)
- zip the folder (# tar czvf backup_home.tgz username/)
- if the screen goes black at any stage during the compression press the SHIFT key to wake the screen up
- once the archive is complete copy this to an external drive
- ctrl + d to exit the root user
