[Bluby]

Hi!
I have 16gb usb.I did format and after that im not ablle to see him in my computer. I see him in mass storage also in computer management, but cant change the letter there either.
Also instead of flashing red light there is a red light all the time.
Any help pls...tnx in advance.

Is the drive visible in disk management? If so, is it formatted?
