Ok im seeing very similar problems on here but no real straight answer. I plug in my 320 gb passport, it showes up in my devices as passport 070A . however, it does not show up in my computer like it used to, and it shows up in diskmangment as "unknown disk" with 2000 gb. This is what im dealing with:
than in my computer it shows up as a CD Drive.
can some one please help me!!!! my comp hd is filling up fast bc i havent been able to use this.
