So I thought my hard drive itself crapped out (was not found at all), bought a new solid state 480 Gb drive... the fast ATI radeon one. Installed it, put everything back togetehr went to INternet Recovery, and tried to restore from Time Machine... still no hard drive found!!! Luckily I have an external hard drive dock that connects USB so I plugged it in, and low and behold... OSX booted! It was the cable!!! Oh well.. solid state will be faster anyway. But until I can get to Apple to buy a cable... (and then figure out how to change it out myself) Is it safe to run OS X from this external dock??? The laptop seems to be getting really hot running it this way (although it's reassuring that all my data is fine after all!) But can I use it like normal for now with the hard drive in the external dock via USB? Is it safe to run like this? Should I be worried about the heat??
