Pendrive Not Getting Detected or Visible

Hello everyone,

I have HP v165w 4GB pendrive that isn't getting detected on any computer, in any USB port. I've tried the control-panel method, it isn't showing up in the administrative tools either. I've also tried uninstalling and then installing back the USB drivers, but it didn't work with it either.

This pendrive is corrupt since 2012 and it contains the video in which my life-partner proposed to me in 2010. I have no other source of that video but this one pendrive that decides to stop working the day I change my laptop and remove the data I didn't need! This pendrive is so important that replacing it is out of question. I need to get it repaired or extract the data out. It's having a great moment of my life captured in it, and it can't just stop working like that! I've been on every forum, every website since 2012 in order to search answers, but nothing worked. I didn't show it to any professional though, because I fear that they might destroy it or corrupt it beyond repair and my proposal video will be lost forever. I can't afford it, please help me, someone!
