So i recently got a MacBook Pro and now im trying to backup my computer using time machine with a USB external hard drive i have. Well problem. A random period of time into the backup (usually anywhere between 100 and 800 MB) time machine will stop backing up and present me with an error saying that it can no longer find the drive or something and that next time i should safely eject the drive before removing it... well silly mac, my hard drive i still plugged in. Well i thought this was maybe just a problem with time machine, nope! i tried manual backing up by just copying some documents and such on to the drive. I had the same problem Please Register or Log in to view images any help?
