Partitioning and Formatting the External Drives
Formatting
Using Apple’s Disk Utility program (found in the Applications folder inside Utilities), the
external backup drive may be formatted on Mac OS X. (Choose Mac OS Extended
format). GUID partitioning is required for boot-ability on Intel Macs.
When erasing the External drive with Apple Disk Utility, be sure to select the drive and
not the volume. (Selecting the drive will repartition drive).
Do not use DOS format for backups; the backups will be much slower and less reliable
(especially for repeated backups).
Partitioning
If you are backing up multiple computers, and want each backup to be bootable, see
“Backing up Multiple Computers” for detailed instructions on installing BounceBack
Software and partitioning the external drive.
