I bought these USB sticks because I could get 10 of them with a storage case for $39. But when I got them and used ChipGenius from www usbdev ru to examine them, I found that they are based on the FirstChip NAND memory chip. From the same site I was able to download the FCCMPTools program and take full advantage of the features that the USB stick has to offer. Of course, if you are not familiar with computers, this may be difficult for you. usbdev ru is in Russian, but you can use Google Chrome to translate into your language and learn in-depth knowledge of working with USB drives. I had one of the USB sticks: push the disc into the USB stick and I was able to fix it with FCCMPTools. Please note that the software is in Chinese, but this version supports English: www usbdev ru/files/firstchip/fc1179mptools/
