I have had the same experience. In my case it was due to overclocking the Pi.

Your situation may be different but if not: make sure your Pi has heatsinks and NO CASE when overclocking. The memory cards and USB sticks corrupt when the Pi overheats!

You can back up your memory card / USB sticks with the Win32 Disk Imager application. Do this before testing overclocks in case your card corrupts. You should be able to format any corrupted cards to get them working again.
