I bought some 32GB and 8GB flash drives from China so that I could sell them here in South Africa. They are all FAT32, copies of Sandisk Micro, IBM thinkpad, Sony VAIO and some pens. I am on Windows XP, all the data can be copied and read from the drives, but when I remove the drives and put them back in, some of the data is lost. If I put multiple folders, only one folders has files which can run, some files become corrupt. The Sandisk Cruzer Micro is corrupted after I tried formatting it, now it doesnt even wanna format. Help please? edit: ALL my other previous working flash drives and my friend's flash drives are in FAT, maybe this is the problem, because these chinese flashes are in FAT32. I cant change format from windows or control panel. any special software?
