Hey there.

Basically it sounds like the flash drive is done for. Sorry to be the bearer of bad news, but having in mind the input/output (I/O) error and everything you've already tried, it doesn't look good.
You could try reformatting it via a different computer and by using its manufacturer's formatting tool, to see if it makes a difference, but it's kind of a long shot.
You could also try some of the suggestions from this article: http://www.wikihow.com/Disable-Write-Protection.

Hope that helps.
