It took me a moment or two to get my head round what you were talking about. So what you have is a 32mb Flash/Memory drive.
Look at it and see if there is a small sliding switch. It may be semi concealed. (hard to find) This is a device, put in place - on many mem sticks - to protect data from being accidently wiped. If it has one, slide it then try it in your PC again.
