Adding something

Two identical internal MacPro Seagate 1TB SATA II hard drives, with identical GUID single volume partitioning, used as the Time Machine repository and a clone of same. Just completed (yet another nightly 800+ GB smart update):

Source: capacity 999.86 GB, available 184.17 GB, used 815.69 GB
Target: capacity 999.86 GB, available 178.64 GB, used 821.22 GB

Time Machine is turned off during the clone. Not bootable, so no post prebinding operation performed.
