3.
In the Disk Utility window, select the new disk on the left side of the
window (select the main entry for the disk and not the indented entry
beneath that shows the partition). Ensure you select the new disk and
not the old one, or you could accidentally wipe your old Time Machine
data!
4.
Click the Partition tab within Disk Utility. Then, in the drop-down list
beneath Partition Layout, select 1 Partition.
5.
Give the disk a name in the relevant field (something like
NEWTIMEMACHINE
would be great), and then make sure the Format drop-down reads Mac
OS Extended (Journaled).
6.
Click the Options button. In the dialog box that appears, click the GUID
Partition Table entry, and click OK. Finally, click the Apply button to
partition the disk ready for use. This process might take a minute or
two—watch the progress display at the bottom of the Disk Utility window.
7.
Once it's finished, close Disk Utility and open Finder. Locate the new disk
in the list in the side pane. Select it and hit
COMMAND
+
I
.
8.
In the dialog box that appears, look at the very bottom. Expand Shared
& Permissions, and ensure there's not a check next to Ignore Ownerships
on This Volume. If the box is checked, click the padlock icon to unlock
the dialog, enter your password when prompted, and then click to remove
the check. Close the info window when you're done.
9.
Attach the old Time Machine disk, ideally in its own USB/FireWire port
on your computer, rather than via a USB/FireWire hub. This will make
the cloning process much faster. Then open System Preferences (Apple
menu→System Preferences), and click the Time Machine entry. Temporar-
ily turn off Time Machine by clicking the switch.
10. Open a Finder window and locate your old Time Machine disk under the
Devices heading in the side pane. Browse the contents of the disk, and
click and drag the
BACKUPS.BACKUPD
folder to the new Time Machine disk.
This will copy across the backup files and will probably take some time
to complete. Remember that while this is happening you aren't protected
by Time Machine backups, so it might be wise to avoid working on the
computer for this period.
11. Once the copy has finished, eject and remove the old Time Machine disk.
Again, activate System Preferences, and click the Time Machine icon.
