I have Ubuntu 20.04 installed on 860 EVO M.2 500GB SSD drive. Single boot os. On last system re-boot there was a message at the bottom of the post screen:
"WARNING! Your HDD/SDD might crash at any moment."
The system still started up and is running fine since.
In addition to the SSD drive, there is another 2TB HDD installed holding backups and non OS data, so my first question is what SSD or HD is the cause of the warning message ?
I'd like if possible to avoid going thru a fresh install, so what is the best approach (assuming the SSD is about to fail) to replace the SSD with similar or larger SSD and clone the system SSD into the new SSD (and then remove the old SSD)
If for example I boot into a live CD and use DD to create an image file of the SSD on an external drive, can I then replace the SSD and again boot into live CD and run DD again to restore the image ? Would that work ?
