cruzer pro without U3 log in and only 77mb of 8 gb seen as being present

My cruzer pro with 8 gb has lost its ability to log in and the memory is not seen after reformatting using the HP disk storage formatting software. Only 77 mb of 8 gb is seen as being present. The U3 software can not be reloaded as it states the USB is not logged in (catch 22). It it locked or dead?

Sounds like the HP formating killed it.

How/when/why did the Cruzer loose it’s ability to log in?  New pc?  PC upgrade?
