Hi guys, First of all: I've tried searching the forums for solutions already, but without luck. If it's already been discussed, my apologies. Please refer me to that thread if that is the case. I'm currently on a 2009 MBP, 2.53GHZ, 4GB DDR3 running OSX 10.6.6. It's in good health and I've never had any problems with it. I'm also the proud owner of a 2TB externally powered (as in: non usb-powered) external HD. Up until recently, it's been working flawlessly. Now, not so much. I made the apparent mistake of leaving it in my car for 10 days - might have dipped below 0 degrees celsius at some point, but not into the extremes. When I plug it into (either) of my USB ports (on any computer, not just my own, I've tried both mac and windows), it doesn't boot. It lights up, starts spinning, but somehow never gets out of "idle" so to speak. Disc Utility doesn't recognize it, neither does the System Profiler. Basically, nothing happens. At all. The only information I've been able to find is in the kernel.log: 407520.760 [0x85b9300] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 1 of Hub at 0x4000000) Feb 5 10:57:22 xxx-xxxx-macbook-pro kernel: USBF: 407523.753 [0x85b9300] The IOUSBFamily was not able to enumerate a device. What the bloody hell is that about? I've been searching the net for this error-message, and the only thing I've been able to find has been regarding Playstations somehow having their power-supply interrupted? Any thoughts would be GREATLY appreciated!
