Got a Sandisc 32Gb Micro-SD card for the wifes phone (Galaxy S2) which has suddenly decided to stop working - phone started to announce 'unmounted SD card' or something - popped it out and into a PC card reader and nothing - no card recognized. Reader is fine as it works with another identical card (from my own SGS2).
Is there anything that can be done to un-corrupt the card? Given that windows won't recognise a device in the reader, I suspect something a bit more 'low level' would be needed - any tips?
The only reference I can find to the card in the device manager is to the card-reader, which comes up as a 'Generic storage device USB Device' - under the volumes tab (properties window) it says there's no media. I've tried a couple of free recovery tools, but none can actually find the device/card.
