If the jumpers are set wrong then windows WILL NOT see the drive, the only 2 things that will stop a drive working that windows can see is the 2 items I posted above, either the drive has fucked or the driver for the drive has fucked and needs reinstalling, nothing else at all will stop the drive working, trust me I do know this for a fact.
What about if a little ant crawled in and planted itself on the laser. But then it fell off and so it worked again. Where are your facts now then, eh, eh.
