USB Thumb Drive Issues?

[mike Enriquez]

I have a 4GB PNY thumb drive that has issues? It has become "Write 
Protected". It is an Optima pro Attache. I searched the net and nothing 
that I have found has helped me out.
Has any one in the group had this happen to them and how did you remove 
the write protection.
I cannot see any special files on it except 2 of my own.
Any suggestions out there?
Thanks
