I sometimes use a flash drive to have photos developed at our mall photo store . I wanted a print of a photo so I loaded it on the usb . When I went to the store there were several photos on the drive . I thought I had deleted them . When I came home and plugged the drive into my mac it only showed 1 photo . How can I delete everything on the drive if I cannot see it . I know I am supposed to move the photos to trash and empty the trash with the drive still plugged in . Obviously I didn't do that for the other photos on the flash drive . Any way to clear the flash completely
Thanks
