Hi, My Packard Bell EasyNote TX86 laptop stopped recognizing my 1 TB Toshiba Store Art hard drive. It worked fine until now, and it still works on other computers. Other USB devices (including storage) work, and I've tried plugging it in every port, to no avail. When I plug it in it spins up, but Windows doesn't react at all (it's not in disk management), Linux doesn't write anything in dmesg and I can't see it in BIOS setup. I didn't use it at all today, apart from plugging it into a freshly-installed Windows 7 machine once (where it worked). What can I do? Which device is to blame here? EDIT: One more thing. I unplugged the drive while the laptop was hibernated. Google says this might be the problem and it might have something to do with resetting the USB Host Controller.
