It may be that the microcontroller on the device has encountered some abnormal condition (totally possible with less than totally reputable manufacturers) and needs to be reprogrammed. This is a bit of a black art and it's likely you will only find Windows programs that can reprogram the microcontroller. You may try opening up the flash drive, looking at the numbers on any chips, and running them through Google to find out who the manufacturer is. You then might do further research to see if there is a recovery, programming, or 'chip' utility available. No standards govern this type of function, so you are looking for something that matches the make and model of the microcontroller or the NAND chip inside the flash drive. There is a good chance that if such a utility exists, that it will be A) Windows only, as stated and B) in Chinese.

In short, the author, running Win OS, examined a functioning USB-stick (the faulty stick and the functional one were both from Sandisk). He found a.dll file on the functional stick and a URL inside the dll (creative idea!) which he tried pasting into his browser. It turned out that the link led to a page for updating the Sandisk driver online!!! Fortunately for the guy, he was running MS Explorer whereby some ActiveX routine formatted the USB-stick to a 'truly as good as new' state. Unfortunately for anyone running Linux, OS X and others, the 'repair-site' spits out the following message: 'In order to install the Launchpad, download the necessary ActiveX component. Please make sure that your browser security settings do not block the download prompt. Press F5 to reload the page'. Of course, there is a possibility of running IE on wine. That is what I will go for.
