Limite de tamaño para FAT32

Windows XP/2000

    "While the FAT32 file system can support drives up to a standard theoretical size of 2 terabytes, (it 'can' be jury-rigged under Windows Millennium Edition to support partitions of up to 8 TB), Windows 2000 Professional and XP Professional cannot FORMAT a volume larger than 32 GB in size using their native FAT32 file system.

    "The FastFAT driver can mount and support volumes larger than 32 GB that use the FAT32 file system, such as those created locally by Windows 98 or ME in dual boot configuration, (subject to other limits listed here for Windows 98, ME and 2000 and here for Windows XP), but you cannot CREATE one using the Format tool from within either Windows 2000 Professional or XP Professional. If you attempt to format a FAT32 partition larger than 32 GB, the format fails near the end of the process with the following error message:
Logical Disk Manager: Volume size too big."

Windows XP Professional File Systems Overview

"The 127.5-GB limit on FAT32 volumes imposed in Windows 98 no longer applies to Windows Me. In Windows Me, using a cluster size of 32 KB, a FAT32 volume can theoretically be about 8 terabytes. However, the 32-bit fields in the partition table (and in the FAT32 boot sector) limit the size of an individual volume (regardless of file system) on a basic MBR disk using a sector size of 512 bytes to approximately 2 terabytes."

"Although Windows 2000 and Windows XP Professional can mount FAT32 volumes of any size, Windows 2000 and Windows XP Professional can format FAT32 volumes up to 32 GB only. Use NTFS to format larger volumes. For more information about the benefits of formatting Windows XP Professional volumes by using NTFS, see 'Advantages of Using NTFS' earlier in this chapter."
