whzhl_12 looks like another ebay fake flash fraudster in China
We strongly suspect that the USB flash drives from ebay seller whzhl_12 will be fake capacity, which corrupts files. If you bought from this seller test your flash drive immediately with h2testw or you may lose valuable data. We advise everyone who buys flash memory items to test them with the free program h2testw irrespective of where they were purchased – otherwise you run the risk of data loss and corruption.
Report your fake if testing confirms you have purchased fake capacity flash memory on ebay.
