my pandriver is not opan

dear sir

            my 2 gb pan drive is not opan but very important data pandrive is opan than show massage the disk in drive i is not formated do u want it format now

don’t format, download recovery software some like to use free tool recuva, but I always use R-studio for this kind of issue. expolore your drive, and save them somwhere else. NOT ONTO THE SAME PENDRIVE.

I haven’t heard anything about pandriver so far. Are you using Sandisk USB stick?
