Getting an I/O Error on a Drive, what do I do?

[Robbbbo666]

I am getting the below I/O error on a Sata SSD.
I am pretty sure there are some app files on the drive, what do I do from here?

I want to buy a new Sata SSD in a different size (500G probably).

Is it a matter of shutting down the server,
Removing the drive
using something like Crucial software to copy the contents over
and refitting the new drive?

Further to this I "MAY" buy a second drive so it can be protected from failures in the future.
