Option B for Mac: using Apple
®
Disk Utility formatting tool
You may already know how to use the built in disk formatting
utility supplied with your Mac. If not, here is a step-by-step guide:
• Your Mac should auto
matically
detect your unformatted Drobo
and display this message:
• Click “Initialize…” to launch the
Disk Utility application which should appear automatically. If it
doesn’t, it can be found in: Applications>Utilities>Disk Utility.
• Select “2.0TB
DROBO USB Ma..” from the list on the left.
Important: Select
the new drive, and
not an existing one
that may contain
data. Reformatting
erases all data on
selected drive.
• Select “Erase”
tab
• Keep default
Volume
Format: “Mac OS Ex-
tended (Journaled)”
unless you need a
different option.
• Type in a name
• Click the “Erase” button.
• After a few moments, Drobo will
complete
initializing and its icon will appear on your
desktop indicating it’s ready to accept data.
Important note: By initializing Drobo as one single
large drive, you’ll never again have to format when
adding or upgrading capacity. However, doing this
causes your Mac to indicate you have “2TB of available space”
when actual space is limited by the drives you’ve installed. You
can determine actual used space by checking the Drobo Dash-
board dock icon (if installed) or Drobo’s blue capacity meter lights.
II. Getting Started
Understanding Drobo’s lights
One of Drobo’s many benefits is a series of onboard lights that tell
you everything you need to know at a glance, without forcing you
to install application software. Here is a list of the Drobo indicator
lights and what actions they may ask you to take.
Hot Tip: Although you don’t need any application software to use
Drobo, we recommend you install the Drobo Dashboard software
from the Drobo Resource CD for its advanced monitoring and up-
dating tools for Drobo OS. Also, be sure you register at Drobo.com.
