I have two pretty new Seagate external hard drives. They are black, shiny USB "expansion" drives. One is 1.5TB and the other is 2TB. Both drives will sit there copying data and then suddenly go into ...

For quite a while now, my USB3 LaCie 1TB HDD starts beeping (a very short, high-pitched sound) sometimes when trying to connect it to one of the ports in my laptop, and refuses to become accessible.
