It was working fine earlier today. Then it got a little slow. So I rebooted. It took longer than normal. A few apps open, then it got very slow and lots of beachballs. Now it won't even fully boot up. If I connect it to my other mac via Target mode it can tranfer files ok for a few minutes, then the firewire logo stops moving around and transfer stops. Even when it does work it transfers slowly. I just did a single user mode startup and fsck. I get a "IOATAController device blocking bus message. Whats up? Time for a Macbook Pro?
