1. Introduction
Thank you for your purchase of your new LaCie d2 SATA II 3Gbits. Based on the
revolutionary new Serial ATA technology, these hard drives feature the latest
technological advancements in interface connectivity and have the bandwidth to
handle both the most demanding applications and environments.
The LaCie d2 SATA II 3Gbits was built for performance, and integrates easily into
systems that require high data transfer speeds to serve up files quickly and efficiently,
maximizing your storage system utilization and enhancing your productivity. These
drives are hot-pluggable and, due to their support of the Serial ATA II specification,
offer serious advantages in terms of reliability, scalability, interoperability and data
integrity.
Being constructed from aluminum alloys, the LaCie d2 Hard Drive actively works to
conduct heat away from the drive. Engineered to fit seamlessly in to any work
environment, the LaCie d2 Hard Drive can be stood vertically on the LaCie Drive
Stand (included), placed in the LaCie Desk Rack (sold separately) or incorporated into
standard 19” computer equipment racks with the LaCie Rackmount Kit (sold
separately). 1.1. What Your LaCie Drive Can Do
• Store and archive your important files and data
• Act as a boot-up disk* under both Windows and Mac OS
• Integrate into RAID 0/1 arrays
• Backup one or more workstations
Tech Note: To take advantage of the bootable feature, the LaCie d2 SATA II 3Gbits Hard Drive must be formatted
as a bootable drive in accordance with the operating system being used. The computer must also include a BIOS
or a Serial ATA PCI card, such as the LaCie SATA PCI Card, that supports bootable functionality with an external
hard drive.

User’s Manual
1.2 Hard Drive Heat Management
Heat Dissipation Design
The LaCie d2 drive’s metal body is ideal for naturally dissipating internal drive heat. Its unique design actually draws heat
away from the internal drive toward the external casing. The casing absorbs heat and will take advantage of its large surface
to further dissipate heat outside the casing. Because of this advantageous feature, heat is taken away from the internal drive,
keeping it safe and prolonging its life and reliability. As a consequence, it is normal that the external casing is hot to the
touch. Please make sure that the vents of the back-bezel and front-bezel are not obstructed so that there is a natural airflow
across the casing.
To Fan or Not to Fan
The casing alone is a great way to dissipate heat without the need of a fan. Therefore, at the date of this publication, most
drives (1 to 3 internal platters*) do not require a fan. Only the largest capacity drives (3 to 5 internal platters*) may need a
fan. To find out if your drive includes a fan, please refer to the item number and product datasheet.
Drives Equipped with a Fan
If your LaCie d2 is equipped with a “smart fan,” it will only start when the heat inside the casing reaches a certain tempera-
ture. Then the smart fan starts to turn at a low and very quiet speed. In exceptionally hot conditions (summer heat, stacked
configuration, etc.) the fan will detect heat and turn to a second, faster speed. Once the heat inside the casing decreases, the
smart fan automatically slows down or stops, allowing for the quietest working environment.
*Indicative information - may vary depending on the internal drive models, manufacturers and technology evolutions.

1. Introduction
page 9
LaCie d2 SATA II 3Gbits
User’s Manual
Upright, Stack & Rackmount Configuration
Heat dissipation is maximized when the drive is in the upright position (1). If you have several LaCie drives stacked on each
other, please remember to attach the included rubber feet on the under side of your drives (2). This will allow for some air-
flow between your drives so that the heat dissipation can work effectively - especially if your LaCie drive does not include a
fan. LaCie does not recommend stacking or racking more than 3 x d2 drives, 2 x Big Disks or 2 x Bigger Disks on top of
each other(3) and (4), especially if these drives are turned ON at the same time.

4. Using Your LaCie Drive
Formatting a disk consists of the following: the operating system erases all of the bookkeeping information on the disk, tests
the disk to make sure that all of the sectors are reliable, marks bad sectors (i.e., those that are scratched) and creates internal
address tables that it later uses to locate information.
As you format the drive, you will have the opportunity to divide the hard drive into sections, called partitions. A partition is a
section of the hard drive’s storage capacity that is created to contain files and data.
Once formatted, the actual available storage capacity varies, depending on operating environment, and is generally about 5
to 10% less than the non-formatted capacity.
Tech Note: Windows Users! You will need to re-format the drive in order for it to appear and operate under the
Windows operating system. See section 4.2. Formatting Your LaCie Drive - Windows Users for detailed
instructions.
File System Formats
There are three different file system formats that are predominately found in Mac and Windows environments:
•Mac OS Extended (HFS+) - for Mac OS 9.x and Mac OS 10.x
•NTFS - for Windows 2000 and XP
•FAT 32 - for Windows Me and legacy operating systems
Important Info: If you will be using this drive between Mac and Windows operating environments, you can
create two partitions: one 32GB FAT 32 volume, and one large Mac OS Extended volume. There are certain
limitations to this configuration, though; to achieve the best performance and reliability, it is recommended that
you utilize a third-party utility, such as Mediafour’s MacDrive, which allows Windows computers to read and
write files on a volume formatted for the Mac.
Mac Users
• If you will be using the drive in a strictly Mac OS
environment, leave the drive formatted as one large Mac OS
Extended volume.
• If you want to be able to install multiple Mac operating
systems on the LaCie Hard Drive, partition the drive into
multiple Mac OS Extended volumes.
Windows Users
• If you will be using this drive between Windows 2000 or XP
environments, it is recommended that you create two
partitions: one that is a 32GB FAT 32 (MS-DOS File System)
volume, and the other as a large NTFS volume.
• If you will be using the drive in a strictly Win 2000/XP
environment, create one large NTFS volume.
