Yesterday the LaCie suddenly stopped mounting on the desktop. I can't access it at all. It does not appear in Disk Utility either. Ive checked the cables and connections. I've plugged it onto a laptop where it appears and functions normally so the problem lies within the computer somehow. I don't know what else to do to fix the situation. Another odd thing is that the second external backup drive, the Seagate, has been disappearing after some of the restarts, then reappearing after other restarts. But even when it's not visible on the desktop it is visible in Disk Utility. Unlike the LaCie which is just completely undetectable.
