How to view/recover photos and videos from my passport for MAC

If you are using your Passport for Time Machine backup, I strongly recommend that you do not store your data on that disk drive. The storage of your data on the same disk drive as Time Machine will cause problems for TM when it needs to cleanup disk space for additional backups. Plus any data stored on the same disk drive that TM is using can't be backup.

I strongly recommend that you get an additional disk drive for your data.

When you backup with Time Machine if you delete the original file off your Mac that makes the backup copy of the file a candidate for deletion from the backup. For this reason, you don't want backup for what you are trying to do.

What you want is another disk drive and move your photos and videos to it. Then make sure the software sees the photos and videos at the new location. Once you do that you can then delete the original files.

This will also allow Time Machine to backup the photos and videos in their new location as soon as you configure it to do that.

Files backup by Time Machine can't be opened without restoring them first back to the disk drive they were backed up from in the first place.

Please explain your current disk configuration?

Within that disk configuration, where are your photos and videos currently stored?
