Formatting a Partition Greater than 32 GB with FAT32

WindowsXP will only format a partition greater than 32 GB as NTFS.
If you want to format it with FAT32:

  • You can use a regular Win98 Boot disk and use that version of FDISK to create the partition (with Large Hard Drive Support)

  • Reboot with the same boot disk and format

  • WindowsXP will then be able to use the partition with no problems

Hidden Format Switches 

There are a couple of undocument Format switches that have been around for several years: They will work with at least DOS 6.2 and above.

  • FORMAT /AUTOTEST - Formats without any prompting and exits the program when finished
  • FORMAT /BACKUP - Like /AUTOTEST but you will be prompted for a volume label
These can be useful if your are formatting drives from a batch file or shortcut and don't want to be prompted for input.

Hidden FDISK Switches 

Here are a few additional switches that can be used with FDISK:

  • /Status - Give the status of the partitions. Similar to option #4
  • /FPRMT - FAT32 in drivers smaller than 512 MB
  • /MBR - Fix master boot record
  • /PRI:xx - Primary partition of size XX in megs
  • /EXT:xx - Extended partitio
  • /LOG:xx - Logical drive in extended partition
