Formatting : The volume is too big for FAT32

What an annoying limitation! You can't format FAT32 volumes larger than 32GB from any version of Windows...

C:\Users\jeff>format e: /FS:fat32 /Q
Insert new disk for drive E:
and press ENTER when ready...
The type of the file system is EXFAT.
The new file system is FAT32.
QuickFormatting 58.9 GB
The volume is too big for FAT32.
Format failed.

... but they must exist because this Lexar USB 64GB drive right here is formatted FAT32! How?

It is possible to do it, you just have to use some other tool. I used this one, FAT32 Format.

Rufus can do this. Start it up, then

  1. choose File system Large FAT32
  2. uncheck Create a bootable disk
  3. uncheck Create extended label and icon files
  4. click Start

You cannot format a FAT32 volume greater than 32Gig from XP or Win7 but you can mount and use a bigger one.

However you must use an alternate tool to format the volume.

There are limitations as to bootable drives on your greater than 32gig Fat32 drive
