I have an external drive set up to do my backups daily. When using my USB hub, everything worked great. Recently I decided to "de-clutter" and when I removed the USB hub and plug the drive in directly it won't read it or do my backups. The drive lights up, you hear it spinning, but it never shows up in Lion as a drive and time machine tells me that I don't have a drive connected. Any ideas from someone smarter than me (which is probably all of you)?
