ENGLISH Troubleshooting PROBLEM I purchased a drive and my operating system reports the capacity as much less than that. PROBLEM The drive is connected to the eSATA port, but the computer does not recognise the drive. RESOLUTION Disc drive manufacturers consider 1 Gbyte to equal 1,000,000,000 bytes. However, your computer operates at a binary level, which considers 1 Gbyte to equal 230, which equals 1,073,741,824 bytes. So, even though a 160-Gbyte drive stores 160 Gbytes of data, when you think in terms of 1 Gbyte = 1,000,000,000 bytes, your system will report a lower capacity due to the operating system's method of calculating the value of each gigabyte. This means your operating system may report that your 160-Gbyte drive has a capacity of approximately 149 Gbytes, the binary equivalent of 160,000,000,000 bytes. Windows-specific problems First, make sure you have the latest Microsoft operating system service packs and other Windows updates installed on your system before you spend time looking for a drive problem. These service packs are issued to fix bugs, add drivers, and enhance the security features of your system. See http://support.microsoft.com for details about how to install service packs and Windows updates in your system. Contact Microsoft Customer Service for information about obtaining these system enhancements if you don't have Internet access. RESOLUTION Check power. Confirm the drive has power and that the power LED is glowing on the drive and power converter. If the light is not lit, press the Power button on the front of the drive to power the drive on. Then check to ensure that all the connections are tight (power cable to wall, power cable to power supply, power supply to drive). If it still does not light up, temporarily remove any surge protectors and plug the drive into the wall outlet. Confirm that the eSATA cable is plugged in to the computer and the drive. For external SATA kits, plug the drive directly into the eSATA port on the computer. Note: When installing a PCI eSATA host adapter, driver installation may be required for optimal performance. Drivers are provided with most host adapters or may be found on the Disc Utility CD in this kit. For the most up-to-date drivers for your PCI eSATA host adapter, see the card manufacturer's website.

Troubleshooting
PROBLEM
I purchased a drive and my operating system
reports the capacity as much less than that.
RESOLUTION
Disc drive manufacturers consider 1 Gbyte to equal
1,000,000,000 bytes. However, your computer
operates at a binary level, which considers 1 Gbyte
to equal 2
30
, which equals 1,073,741,824 bytes.
So, even though a 160-Gbyte drive stores
160 Gbytes of data, when you think in terms of 1 Gbyte
= 1,000,000,000 bytes, your system will report a lower
capacity due to the operating system’s method of
calculating the value of each gigabyte. This means your
operating system may report that your 160-Gbyte drive
has a capacity of approximately 149 Gbytes, the binary
equivalent of 160,000,000,000 bytes.
Windows-specific problems
First, make sure you have the latest Microsoft operating
system service packs and other Windows updates
installed on your system before you spend time looking
for a drive problem. These service packs are issued to
fix bugs, add drivers, and enhance the security features
of your system. See http://support.microsoft.com for
details about how to install service packs and Windows
updates in your system. Contact Microsoft Customer
Service for information about obtaining these system
enhancements if you don’t have Internet access.
PROBLEM
The drive is connected to the eSATA port, but
the computer does not recognise the drive.
RESOLUTION
Check power.
Confirm the drive has power and
that the power LED is glowing on the drive and
power converter. If the light is not lit, press the
Power button on the front of the drive to power
the drive on. Then check to ensure that all the
connections are tight (power cable to wall, power
cable to power supply, power supply to drive). If it
still does not light up, temporarily remove any surge
protectors and plug the drive into the wall outlet.
Confirm that the eSATA cable is plugged in to
the computer and the drive.
For external SATA kits,
plug the drive directly into the eSATA port on the
computer.
Note:
When installing a PCI eSATA host adapter, driver installation
may be required for optimal performance. Drivers are provided
with most host adapters or may be found on the Disc Utility CD
in this kit. For the most up-to-date drivers for your PCI eSATA host
adapter, see the card manufacturer’s website.
