I don't know if this is a dumb question, but I have a WD external, and it will not stay on unless I have a house fan blowing into it. If not, it will eject itself from my computer. Do those have fans inside that keep them cool?
OK, last night I took my external and installed it in my computer. I have another external HD and now it will not even show up. It is being recognized bc I get the option to eject my hard drive, but it does not come up in my computer tab.
