So far only a few file. I am wondering if something more profound happenIs 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.My host said: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.If you require any further assistance feel free to update this ticket.
Is my SSD broken?
