FWIW, I bought some of these same flash drives about a year ago, and all 3 of them died within a day or two of starting to use them. They worked at first, but became unreadable in any of my machines almost immediately, with very little data transferred to them. I can’t even re-partition or re-format them. The computer just says “no.” YMMV.
Mine were absolutely garbage too. All of them failed after a month. Starting giving them out at work when people ask me for a flash drive so they never ask me again. I posted about it elsewhere where others also complained about it.
Please don’t buy this junk anyone. Even when they “worked” they would constantly freeze and stop transferring start, freeze, start, freeze and start until it finished. I should have returned them but such is life.
