I have a Micro Center branded 128 GB USB 3.0 flash drive. Last month, I transferred TV Show episodes to it. While it seemed to take a longer-than-usual time to transfer, all of the files came up. Two days later, I plugged it in to my tablet and the tablet didn't recognize the drive. Next, I tried it in the original PC and it came up. I could play the files and everything seemed normal...until I tried to delete the files. I would right-click on them and there was no option to delete. (odd...) So, I tried to format the drive in exFAT (recommended). It told me the drive was write-protected...?????? I never write protected it and there is no mechanical switch to do so either. Both the files AND the drive itself claim to be write-protected. So, I turned to Google. I tried ALL of the suggestions on there (Registry Editor, Safe Mode format, Command Prompt disk attributes, etc.). My next step is to use Hiren and try to boot into a non-Windows based environment to see if that will do the trick. Any other suggestions? Is it possible that it's permanently read-only?
