I bought 10 128 Gb USB Flash Drives from a supplier in China by the name of Gogoea, paid $ 39.00 a piece, they are Kingston Data Traveler USB 2.0, they all failed to work after a couple of times using them, they loose information, some aren't even recognized, but in general they are not wokring. I heard that there is a way to fix this problem, even though you have to sacrifice capacity, reducing them to probably 64 or 32 Gb, but that is beter than loosing them. I had to reformat some of them, but I couldn't format them in FAT 32 of NTFS, I had to format them in ExFAT, the new format of Microsoft, but not only there is a problem to read them on Windows XP or Vista without Service Pack 1, you have to update Windows XP to be able to read this new format, and still they are not working. Any help will be highly appreciated.
