SanDisk Extreme 500 portable keep restore finder problem

Dear Forum

My SanDisk Extreme 500 portable keep asking for restoring finder problem on my macintosh…

every time I click the icon… then the restore window keep restarting… please advice

what version of Mac OS are you running?

do you have a similar issue with any other removable drive?

is this a first time use or did it work normally before?

did you reformat the drive? If so what file system did you use?

How does the drive show up in disk utility?

Have you tried the drive with any other system? If so what is the result?
