GNODSON 256GB Silver 3.0 Storage Thumb U Disk Waterproof USB Flash Drive Metal Pen Drive Real Capacity cle USB Memory Stick Key Chain U Disk for Computer car Office (256GB)

After I copied a lot of files, I noticed them dropping off in front of my eyes. I had two windows file explorers open and was copying and pasting one to the other. I actually saw the files get copied to the jump drive and they deleted in front of me. I thought there was a hacker in my computer. But it happens on different computers as well. I tried many times on different operating systems to format this drive, but it fails every time at the end of the format. I tried this with Windows 10 and Windows 7 using NTFS, fat 32 , xfat, etc. I also tried different sizes and I tried both USB 2.0 and 3.0 ports. It fails every time no matter how I tried it. I like the design, but it useless if it won't hold files.

Please guys don't buy it. I just bought it. And everything that I put on the USB is getting corrupted. Its ridiculous. don't think I don't know how to use it . I'm an expert IT.

This sucks it deleted my pictures and was getting error . Waste of money and lost pictures I can’t get back
