Passport won't backup - says "read only"

My passport randomly stopped backing up. It states unable to backup because "read only" yet made no changes. Thought it was a disk failure and bought a new one and it has the same error after installing.

Hmmm, pretty strange‽


Run one of these...


You can use Drive DX to possibly get a better view of Drive health…

Thanks to Jack-19…

It may be wise to run SMART Utility to check the drives' health. 


We need to see what all is running, a report from this will not display any personal info...
