I just purchased a SimpleTech USB Simple Drive, because I was told that it would work for Mac. But when I plug it in my computer wont recognize it? I am plugging it into my USB drive on the side of my powerbook... and it is not showing up when I run disk utility. I also just noticed that once I unplug it from the USB, that drive does not work, until I restart, for example if I plug my mouse in, it will not work. Any suggestions?! I am running OSX 10.3.9.. Please help. Thankyou.
