I have Sandisk 16 GB and 32 GB Pendrives. I use Win32DiskImager and UniversalUSBInstaller and lili etc for each one 16 and 32 GB pen drives. For 16 GB is working successfully but 32 GB it says unable to find a medium containing a live file system. And this is not happening with me but also to my friends having 32 GB USB. Why is this happening and what is the solution?
