I have a 2TB My Passport Ultra Hard Drive and it's been acting up. I use it to store all my photos and videos and I've had it for about 2 months now. It's had some weird behaviours before sure as not working in USB 3 Ports on multiple computers, which is a whole other issue, but now the drive is starting to either delete or hide files - I'm unsure. But now mutliple files from different locations in the drive aren't showing up and years and years of work is completely gone. Is this a malfunctioning drive or is it something in windows (The files don't show up when drive is in both Mac or PC) Please help.
