was going to post exactly the same thread, and noticed this thread as the first one.
I have the same exactly problem, a Corsair FlashVoyager 16GB. It's barely been 2 months, and the drive now says 'Insert Disk'. I've tried also using 'diskpart' (as previously it worked with another pendrive), to repartition the drive, but it lists it as 0byte size.
Any further insight on this problem?
