Seagate 3.5-inch Pushbutton Backup External Hard Drive Quick Start Manual page 20

PROBLEM
The Macintosh OS displays the following message
when I connect the drive to my system: "Unable
to read volume—must initialize."
RESOLUTION
Your Mac OS does not recognize the drive format.
Use Apple's Disk Utility to initialize the drive with a
Mac OS Extended format.
PROBLEM
For dual-interface kits only: My system doesn't
have a 6-pin FireWire (IEEE 1394a) connector.
It has a 4-pin FireWire connector, so the cables
don't match the connector.
RESOLUTION
Purchase a 4-pin to 6-pin FireWire (IEEE 1394a)
cable to connect the drive to your system.
Note. A 4-pin to 6-pin FireWire (IEEE 1394a) cable is not included
with the drive because 4-pin FireWire connectors are not provided
on most systems.

PROBLEM
Daisy-chained device does not work when
plugged into second FireWire (IEEE 1394a)
port on my External Hard Drive.
RESOLUTION
Make sure FireWire (IEEE 1394a) cables are used
throughout the entire daisy-chain connection to
the computer. Make sure all External drives are
powered on. Power is required on all units that
the data passes through.
