LaCie 2big Quadra Enterprise Class • Design by Neil Poulton User Manual RAID page 20 3.4. Formatting and Partitioning The 2big Quadra comes pre-formatted in HFS+ (optimized for Mac OS X). Please read the following information on file system formats for Windows and Mac operating systems to determine if you need to reformat the 2big's disks. See sections 3.4.2 and 3.4.3 for formatting instructions. 3.4.1. File System Formats Windows Users TECHNICAL NOTE: The LaCie 2big Quadra comes preformatted in HFS+ for optimum performance with Mac OS X. TECHNICAL NOTE: Windows XP 32-bit does not support volumes greater than 2TB. Windows XP x64, Windows Vista (32- and 64-bit versions), and Windows 7 (32- and 64-bit versions) do, but in order to create volumes bigger than 2TB from these operating systems, you must convert the disk to GPT file system. This process is outlined in 3.4.2. FAT 32: FAT is an acronym for File Allocation Table, which dates back to the beginnings of DOS programming. Originally, FAT was only 16 bits, but after the second release of Windows 95 it was upgraded to 32 bits, hence the name FAT 32. In theory, FAT 32 volume sizes can range from less than 1MB all the way to 2TB. It is the native file system of Windows 98 and Windows Me, and is supported by Windows 2000, Windows XP, Windows Vista, and Windows 7. When FAT 32 is used with Windows 2000, Windows XP and Windows Vista though, volume size is limited to 32GB (by the Windows partition utility, i.e. Disk Manager), and the individual file size is limited to 4GB. NTFS: This acronym stands for New Technology Filing System, and it is the native file system for Windows NT, Windows 2000, Windows XP, Windows Vista, and Windows 7. NTFS offers several features that are not available with FAT 32; i.e. file compression, encryption, permissions, and auditing, as well as the ability to mirror drives and RAID 5 capabilities. The minimum supported volume size for NTFS is 10MB, with a maximum of 2TB when initialized in MBR format or without a limit when initialized in GPT format, with no limit to file size. Volumes created in NTFS can only be directly accessed (not through shares) by Windows NT, Windows 2000, Windows XP, Windows Vista, and Windows 7 without resorting to help from thirdparty products. Windows File System Formats There are two possible file system format categories for Windows users: NTFS and FAT 32 (MS-DOS). See the table below for more information. Use NTFS if: ...you will be using the drive with Windows XP, Windows Vista, and/or Windows 7 only (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 FAT32 if: ...you will be using your drive with both Windows and Mac OS 9.x or 10.x or sharing the drive between Windows 2000, XP, and 98 SE. Maximum single file size is 4GB.

Windows Users
TECHNICAL NOTE:
The LaCie 2big Quadra comes preformatted
in HFS+ for optimum performance with Mac OS X.
TECHNICAL NOTE:
Windows XP 32-bit does not support volumes
greater than 2TB. Windows XP x64, Windows Vista (32- and 64-bit
versions), and Windows 7 (32- and 64-bit versions) do, but in order
to create volumes bigger than 2TB from these operating systems, you
must convert the disk to GPT file system. This process is outlined in
3.4.2
.
FAT 32
: FAT is an acronym for File Allocation Table, which dates
back to the beginnings of DOS programming. Originally, FAT was
only 16 bits, but after the second release of Windows 95 it was
upgraded to 32 bits, hence the name FAT 32. In theory, FAT 32
volume sizes can range from less than 1MB all the way to 2TB.
It is the native file system of Windows 98 and Windows Me, and
is supported by Windows 2000, Windows XP, Windows Vista, and
Windows 7. When FAT 32 is used with Windows 2000, Windows XP
and Windows Vista though, volume size is limited to 32GB (by the
Windows partition utility, i.e. Disk Manager), and the individual file
size is limited to 4GB.
NTFS:
This acronym stands for New Technology Filing System, and
it is the native file system for Windows NT, Windows 2000, Windows
XP, Windows Vista, and Windows 7. NTFS offers several features
that are not available with FAT 32; i.e. file compression, encryption,
permissions, and auditing, as well as the ability to mirror drives and
RAID 5 capabilities. The minimum supported volume size for NTFS
is 10MB, with a maximum of 2TB when initialized in MBR format
or without a limit when initialized in GPT format, with no limit to
file size. Volumes created in NTFS can only be directly accessed
(not through shares) by Windows NT, Windows 2000, Windows XP,
Windows Vista, and Windows 7 without resorting to help from third-
party products.
Windows File System Formats
There are two possible file system format categories for Win-
dows users: NTFS and FAT 32 (MS-DOS). See the table be-
low for more information.
Use NTFS if:
...you will be using the drive with Windows XP, Windows
Vista, and/or Windows 7 only (performance will generally be
greater when compared to FAT 32). This file system is com-
patible in read only mode with Mac OS 10.3 and higher.
Use FAT32 if:
...you will be using your drive with both Windows and Mac
OS 9.x or 10.x or sharing the drive between Windows 2000,
XP, and 98 SE. Maximum single file size is 4GB.
