Fake32GB Kingston pendrive

Hello,

I have recently purchased 32GB Kingston pendrive from a boy who was selling it on footpath for Rs.300/-
On the very first day I copied around 70-80 photos from my mobile to this pendrive. But later after a couple of days I found that I had lost every thing which I had copied on this pendrive. Now whenever I attach the drive i get a message saying insert disk. Can this pendrive be repaired? Actually I tried repairing it thru the programme written on the fake 32GB blogspot, but it didn't worked for me. Please let me know how can i repair this in simple language as I am not so tech savvy. One of my friend advised me to throw away this pendrive as he said it is of no use. I want to make a last try and if it doesn't work this time, I have no other option than to throw it.
