As I am currently having issues with my M4 playing hide and seek, Iv'e been scouring the internet for a fix. Sadly I couldn't find a cure for my problem but did notice that quite a few have reverted back to 0309 from the 000f. But crucial have announced today via their forum that there will be a new firmware update late next week. http://forum.crucial.com/t5/Solid-St...te/td-p/107660
