is the external HDD brand new? ... if so, it may need to be formatted. Does it show up in disc management (not devise manager - disc management)

I think it's very likely your drive has crashed. i guess it is possible that it could be the little board inside the case that the hard drive plugs into (usb to sata). Can you easily remove the hard drive from the case it is in and put it in a different external hard drive case and test. Empty usb hard drive cases cost only $10 (where I live) so that might be worth the gamble.

If the hard is the actual problem - I believe there is hardware that can attempt to repair it - but I don't know anything about that - especially considering that your machine cannot even find the drive. Maybe someone with more experience at this will answer this post.

Anyway, i would try to get the hard drive out of that case that it is in .... put it in a different portable case and hope for the best.
