Hello,
I have a DT310 256GB mem stick. it allows pics & doc's to be loaded and used but when I remove from laptop and put it back, there is no data etc. it shows a lock pic. how do I unlock?

U may have a switch or a slider on the USB stick to turn off the write-protection.
If not, try this USB Flash Drive 101 guide
