Sandisk has their secure access folder. the other drive I was using has wmp device folder. Strangely, I got the sandisk to read from rear usb slot but not from front (both dedicated to devices). next attempt I could not see the files I saw and listened to earlier. They are still on the stick. It seems like a problem with the T2, randomly recognizing and accessing the folders/files, then not. Data is good. Same on two different sticks. Tried powering on and off a few times. It has to be something quirky...like the time power went off and back on a couple times within about 10-15 seconds in house when my friend was backing up reg info to usb stick. lost a couple of custom sounds that afternoon..probably fried something in port/board..probably require a repair that's not worth it. And where do you go for something like that in NJ?
