the flash disk on my manova 128mb has stopped working?

does anyone know how to fix it? everytime I put it in my computer to drop files on it it says do you want to format drive - and I don't really want to do this in case it breaks it not that it is working what I mean is I don't want to make it un fixable - has anyone got any advice? I've heard about flashing the drive but I can't find how you would do it! I have also looked on the web for the manova website so I could send it back as I have only had it 7 months - sods law I threw the box out 3 weeks ago and then it broke!
