By "stem" I assume you mean the part you put into the USB port?

You MAY be able to buy another same flashdrive and try to "engineer" one working one

I've never had one apart, so in your case, you may as well try what you can....good luck!

I use mine to xfer files or share pictures; never trust one as a storage device (i.e. make sure you have your data backed-up )
