Formatting and Partitioning
What is Formatting?
■
When a disk is formatted, the following things oc-
cur: 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 ad-
dress tables that it later uses to locate information. Your
LaCie Hard Drive is preformatted in FAT-32 (MS-
DOS) format. To reformat your drive, follow the in-
structions in this section.
What is Partitioning?
■
You can also 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. For instance, you could create three partitions
on your drive: one partition for your office documents,
one as a backup and one for your multimedia files. Or, if
you will be sharing the drive with another person in your
household or office, you can create a partition for each
person who uses the drive. Partitioning is optional.
File System Formats
■
There are three different file system format catego-
ries: NTFS, FAT 32 (MS-DOS), and Mac OS Extend-
ed (HFS+). See the table, right, for more information.
Once you’ve connected your drive and it is recog-
nized by your operating system (i.e. Windows or Mac
OS X), you are ready to format and partition the drive.
In order to store information on a hard drive, it must
have a file system and be divided into sections that will
contain the data you wish to store. This process is called
formatting
.
ImpOrTANT INfO:
Reformatting will erase
everything from the hard drive. If you have infor-
mation that you want to protect or continue to use,
back up this information before reformatting.
3. Formatting and Partitioning
Use NTFS if...
...you will be using the drive only with Windows
2000 or Windows XP (performance will generally
be greater when compared to FAT 32). This file
system is compatible in read only mode with Mac
OS 10.3 and higher.
Use HFS+ if...
...you will be using the drive on Macs only; perfor-
mance will generally be greater when compared to
FAT 32. This file system is NOT compatible with
Windows OS.
Use FAT 32 (MS-DOS) if...
...you will be using your drive with both Windows
and Mac OS 9.x or 10.x or sharing the drive be-
tween Windows 2000, XP, and 98 SE. Maximum
single file size is 4GB.
TeChNICAl NOTe:
The LaCie Hard Drive is
preformatted in FAT-32 (MS-DOS) format, op-
timized for use with Mac and Windows OS. See
File System Formats, below for explanations of the
other possible file formats.
