i got a whole bunch of photos and videos in the one back up of the pics... on the second one there are just the photos.., both drives work. so why do they freeze and not load the folder. but i can open another window and load anything else. note some of the photos i added were from a recover of a micro sd card that thought they lost them. also cd rom drive freezes when i try to explore it and random folders on other hard drive. just really weird stuff happening.
