CCC requires an HFS+-formatted target volume. Why? And how do I format my new hard drive as HFS+? |
||
Mac OS X is installed on an HFS+ filesystem. The HFS+ filesystem defines many types of metadata that describe non-data attributes of your files. Creation date, access control lists, permissions and ownership, Finder flags, and extended attributes are among the various metadata types defined in the HFS+ standard. To adequately back up all of your files and their associated metadata, CCC requires that your backup volume is also formatted as HFS+.
Additionally, Macintoshes can only boot from hard drives partitioned with either the Apple Partition Map (APM) scheme (PowerPC- or Intel-based Macs) or the GUID Partition Table (GPT) scheme (Intel-based Macs). The hard drive icons that you see in the Finder are volumes. The partition scheme of a hard drive describes how volumes are physically defined on the hard disk. Every hard drive has exactly one partition scheme and at least one volume. When you "partition" a hard drive, you simply create multiple volumes on that hard drive.
See the section of CCC's documentation labeled "Preparing a hard drive for use with Carbon Copy Cloner" (in the "General overview of the features of CCC" section) for step-by-step instructions for partitioning and formatting a new hard drive for use with CCC.
