A friend of mine ask to borrow one of my usb sticks, so I loaned him a verbatim 2 gb one. Before giving him the usb stick I formatted and it worked just fine.
He took it to a internet cafÃ© to copy some stuff of the net. When he put in the usb stick it didnâ€™t work, he tried it on a different PC and it didnâ€™t work on that one as well.
Now he went out a bought a new usb stick, a 4 gb one and went back to the internet cafÃ©. He tried that one on 2 more PCs. That one didnâ€™t work as well. So he went back to the shop, they tried it on their PC and it worked there. He returned it and they gave him a new one, 4gb Apacer. He went back to try that one, which also didnâ€™t work. He went home tired it on his laptop, it still wouldnâ€™t work.
Then he gave me my old usb stick and his new one to try on my PC. I tried them on 2 PCs at home, both didnâ€™t work.
Any idea what could have damaged the memory sticks? Is my friend emitting some kind of radiation that is deadly to memory sticks or something?
Anyone have any idea what this could be and could someone please share a method how I can test the usbs or something.
