MyPassport for Mac Just Died

Help!  MyPassport for Mac just died and all the data from my computer was stored on it while I was upgrading my OS.

How can I gain access to the data?  I need it ASAP.

Also, why would MyPassport just die?

Did you tried using another USB cable or connecting the passport to another computer? Another option is to check the disk utility app and see if the passport is recognized there, if it is, try pressing on the repair disk button.
