I ordered 2 SSDs from my provider.
However, which drive is the main drive?
How do I know which drive is the new SSD drives?
You could check it by using the command
It will give you all the mounted file systems. What you are interested is where the root file system is mounted (i presume thats what you mean by main drive).
This is my sample output of the mount command (just the line which contains the main disc)
What it says is that the partition sda1 (just sda represents the disn, sda1 represents the partition) is mounted as root. So now we know that the main disc is sda. Now we have to check what disc is actually sda.
Chech that with
My output is
From which we can see that sda is the 500GB Toshiba disc.
will give you further details
