Posted by flashchiptutor on March 26, 2009

Beware Sony Microvault model USM4042 advertised as 32GB with a packaging label of 32G is a counterfeit – fake! Sony never produced this usb flash drive. Sold on wholesaler internet sites in China and Hong Kong. Often sold as “upgraded” – there is no such thing. This drive is unlikely to have a real capacity of more than 512MB. This model is the favorite Sony Micro vault counterfeit sold on eBay. It comes in other sizes and packaging. Avoid being frauded or scammed. Do not buy this usb flash drive, you risk data loss. Do not sell this usb flash drive!
