With Mac OS X Leopard just released, almost everyone has bought an external hard drive so they can use Time Machine. I plan to do the same thing, however I'm concerned about hard drives failing, crashing and dying after some time. Obviously, hard drives are made up of moving parts which make them vunerable to damage. Are there are tips, in terms of locating my hard drive, using it, using partitions and so on, which can help protect my external hard drive. I'd rather not have to back up my back ups. Thanks very much!
