Click on the drive (the upper listing with the numerical capacity) that you wish to partition. The drives are displayed on the left side of the window. Open the main drive (the drive that contains the operating system). For directions on how to partition and format an external hard drive, please follow the directions below:Įnsure that the external hard drive is connected to the computer and powered on. The external hard drive must contain a Mac OS Extended (HFS+) partition with GUID for Intel-based computers or Apple Partition Map on PowerPC-based computers. The following external hard drives should not be bootable on Intel-based Mac computers systems through FireWire (1394a/b):

Not knowing what version of OS X you are running: The self-powered hub will make up any shortfall of current in the USB port. You may bneed to get a powered USB hub (has its own power supply from teh wall) and place it between the Passport and the MBP. Often, this is more power than a USB port on a notebook computer can provide, especially as the drive ages. Also, the Passport does not have its own power supply and must get power to turn the platter motor and run the electronics from a USB port. If the WD software folder has an uninstaller, try running it. There are also recent reports here of WD software not playing well with Mac OS 10.9 Mavericks.

Time Machine without any third-party backup programs is the least intrusive backup scheme. WD's backup software is intrusive and, for me, slowed overall computer performance-including lockups-to the point I gave up on it. However, if you installed the WD software that came with the drive, that could be part of the problem. Help me understand-the Passport has password protection separate from anything Mac OSX provides? Wasn't aware they were doing that.
