My Micro SD (Sony 8gb) is recognized well by my mobile device and other mobile devices but when I try to connect it to any PC it simply doesn't recognize it, It's not the PC configuration, it's not the via to connect it (Tried directly to a micro sd port, adapted to a sd port, using the usb cable from the mobile, adapted to an usb), it's not that it's switch is "locked".

The problem is the Micro SD itself, if this requires formatting (or simply doesn't have solution) then may someone tell me a way to get it's content into another SD or a PC?
