Well the fact that you can recover the data is good news. If you have no place to put them, well, that is bad news. Surely you have a friend who can let you borrow some diskspace for a day or two?
Alternatively, you can do a little cheat... But I will warn you, it is "not fair and not sportsmanlike" as a certain comic character would put it.
You will need a little liqudity - some money you can live without for a couple days (you will get them back, don't worry).
Now, go and find an electronics store in your area, that does a sensible money back guarantee - at least 7 days. Make sure it actually works - ask around, google around, make a bogus story to tell the store clerk.
Now I am not sure what kind of use for an external disk you can think of, that would render the disk unusable, but you can not know it beforehand... Maybe you wanted to use it to store HD videos that you would stream on LAN to your TV, but some part of the chain is too slow or something.
Anyway, use the disk to store the recovered files, re-format your disk, copy back, put the "bought" disk to original state, and go return it.
