Hello evelymont i found a solution to our problem!!try to download HP USB Disk Storage Format Tool and try to formta the flash stick to fat32 file system!!And after that you're ready to store any file you want unless you put them in a folder first because of the fat32 file system and not saving them on the root for exaple if you want to store an avi file at E: where E: is your kingston usb data traveler save the avi like this e:/name of the folder/avi file, and not in the root e:/avi file!!
that 's it !!congrats for your buy!!
