What does input/output error mean>?
How do I make sure that it's broken. So far only a few file. I am wondering if something more profound happen
Is there a way to prove to my provider that it's indeed a problematic SSD?
Also, can I try to just reformat the disk?
I am concern that there is a bad sector on that disk.

We will only replace the drive if we can identify a problem with it. The permissions error you encountered is not an indicator of a failed drive.
