A noter : sous Windows XP, il n´est pas possible de formater des volumes en FAT32 de plus de 32 Go. L´astuce consiste à les formater en mode DOS.

" You cannot format a volume larger than 32 gigabytes ( GB) in size using the FAT32 file system during the Windows XP installation process. Windows XP can mount and support FAT32 volumes larger than 32 GB ( subject to the other limits), but you cannot create a FAT32 volume larger than 32 GB by using the Format tool during Setup. If you need to format a volume that is larger than 32 GB, use the NTFS file system to format it. Another option is to start from a Microsoft Windows 98 or Microsoft Windows Millennium Edition ( Me) Startup disk and use the Format tool included on the disk."
Donc :
Télécharges une BONNE disquette de démarrage de Win98SE qui contient une version de FDISK capable de prendre en charge les disques de grande taille ( >64 Go) à : http://www.bootdisk.com/bootdisk.htm
