I just got my My Book in the mail today and I was setting up, following the instructions. I wanted to use this backup my macbook that is running Mac OS X Version 10.7.5. It is all up to date on software updates. Whenever I try to start the back up, it will transfer about 4-5GB and then say the hard drive was ejected unexpectedly, and then the back up stops. It has done this about 5 times now. I have turned off sleep mode and screen savers to prevent the computer from shutting down. I made sure that the hard drive and the computer are using the same format in Disk Utility. Any help would be nice so I can get a safe back up of my laptop.
Thanks in advance.
