So ever since I received the latest dashboard update. My Xbox refused to read one of my hard drives. I have a second one that worked fine. Now that also won't be read. They are both fine on the computer. Now stuff can't even be installed properly. Still have space on my internal. But the apps I had, I can't even redownload them. Attempts to and then just tells me the installation has stopped.

What can I do?

Only had these problems since the new update. Very annoying.

EDIT: the one that initially stopped was Seagate, after further research. Seems to be that they are notorious for failing and maybe fucked my other one too. Still shows up on the PC, so I my just format that one and see what happens
