Mac OS X Users:
The LaCie 2big USB 3.0 comes preformatted in NTFS, a file sys-
tem native to Windows. While Mac OS X can read NTFS, writing
data is not supported. You may customize the drive by reformat-
ting and/or partitioning the 2big USB 3.0 for optimal perfor-
mance in Mac OS environments.
Mac OS Extended (HFS+)
Mac OS Extended refers to the file system used by Mac OS X.
HFS+ uses hard disk space more efficiently and is not limited by
block size.
MS-DOS File System (FAT 32)
This is the Microsoft file system, more typically known as FAT 32.
Use this file system if you are going to move your LaCie hard disk
drive between Mac and Windows operating systems.
File System Formats
There are two file system formats recommended by LaCie
when using the 2big USB 3.0 with the Mac OS – Extended
(HFS+) and FAT32 (MS-DOS). Use the information below
to determine which format is best for you.
Use Extended (HFS+) if…
...you will be using the drive only within a Mac OS X envi-
ronment. This file system is not compatible with Windows.
Use FAT 32 (MS-DOS) if…
...you will be using your drive with both Windows and Mac.
Maximum single file size is 4GB.
