Disk Management (Disk Format)
To format a hard drive or array, select it from
the Target Disk dropbox. Choose the file
system desired from the File System dropbox
(internal drives can only be formatted with
XFS). Note that FAT32 has a 4 gigabyte file
size limit. If you choose FAT32 for your file
system, you will not be able to store files
larger than 4 gigabytes on the drive. Buffalo
Technology recommends the XFS file system.
Press Select Target Disk when done.
Depending on the size of the target hard disk
or array, a Disk Format may take several
hours to complete.
