3 TB my passport

I need advice on how to restore images to this device, it decided to delete things… I dont know why it did it but im 100% sure i didnt prompt the deletion nor wanted it to. I transfered almost a full tb of images and videos from my usb flash drive to the passport thru my desktop … no music tho, after all transfers were completed i disconnected the passport from my d.t…and when i reconnected the passport alot of my family pictures & videos were gone from the passport.sadly after i transfered the data to the passport i cleared the thumb drive…should have known better to trust the device before being assured it worked properly…lesson learned please advise

Hello,

If you wish to recover deleted files from the drive I recommend you try using a data recovery software.
