Fat32 Formatter Windows 8.1 Download
Carmen Martinez
Actually, looking back at the Microsoft comment, if I could format the volume myself, all would be OK. Fat32 is pretty simple, so it occured to me to write a fast format routine to do the job. Note that the 32GB limit is a limit of the formatter in Windows XP. FAT32 itselft should be OK to 2TB, limited by a 32 bit sector count in the boot sector. XP comes with a partitioning tool, called Disk Management. It even has Wizards for partitoning. This should be a cinch.
You can download either just the fat32format binary 20K or the fat32format binary and source 30K The source code can be compiled with Vistual Studio 6.0 or later. The current version number is 1.01.
There are a couple of things you need to know before running fat32format. You need to have Administrator rights on XP for it to work, since it opens the drive in raw write mode. You also need to make sure that there are no open files on the volume - if there are you will see a message like this -
This should make it a bit harder to lose data, assuming that you have at least one open file on the drives with data you want to keep. The drive that Windows is currently running from will have lots of files open - the pagefile, registry etc. I usually keep an Explorer.exe open in the root directory of any other drives to block format from running. Finally, it will only work with hard disks with 512 bytes per sector. If you have a DVD-Ram disk, format using the Windows formatter. If you have an optical disk drive bigger than 32GB, send me a sample and I'll port to it.
fat32format works with Vista. The UI has changed a bit when creating drives and UAC makes the whole process a bit more cumbersome. To create drive letters, Right Click on My Computer and Select Manage. UAC prompts you to escalate privileges, do so. You can right click on empty drives and Initialize them. Once you've done that you can create new volumes by right clickingon them and selecting New Simple Volume. Fast formatting them with NTFS is quick and should detect a completely dead drive.
If you have Vista there is a quick way to get an Admin cmd prompt. Click the Start button/ Windows flag inthe bottom left of the screen and enter cmd like on XP but press Ctrl+Shift+Enter, you'll get a privilege escalationdialog click OK and you end up with an Admin command prompt, helpfully labelled as Administrator: C:\Windows\system32\cmd.exe This is the best way to run fat32format. It's always been Admin only, it's just that on XP most power users ran with Admin rights all the time.

A couple of people asked me about 64K cluster size. There are compatibility problems with this, as 16 bit set up programs sometimes assume that the cluster size will fit in a 16 bit integer. When calculating disk space, they thus end up with a value of zero. Fat32format disables cluster sizes bigger than 32K for this reason. However, some people need this, so the current version has the check disabled. You still need to force the cluster size by hand though, e.g. fat32format -c128 f:
1.03
Fixes for making partitions created above sector 0xffff bootable, and a cosmetic fix for the drive size printout when formatting drives bigger than 1TB ( 0x7fffffff sectors )
1.04
Fix for "Failed to set partition info". Some drives have no partition table, so you can't set the the partition type.
It was possible to set the cluster size too high resulting in too few clusters, or too high resulting in too many -fat32 must have between 2^16 and 2^28 clusters because of various compatibility considerations. Added code to check that.
Fixed an error where it crashes if people use /? to get help
1.05
Added support for bytes per sector values of other than 512
1.07
GPT support, fix for boot sector when using Windows AIK's bootsect.exe, FSCTL_ALLOW_EXTENDED_DASD_IO

Are you looking for a professional FAT32 formatter to format your USB flash drive, external hard drive, SD card to FAT32 for better compatibility? This post will show you some ways and you can try them according to your needs.
Usually, there are some important files stored on the USB drive, SD card, memory stick or external USB hard drive. When there is a need, it is a better solution to adopt a professional FAT32 formatter tool to convert NTFS to FAT32 because of the limits of Windows Disk Management. (We will show you some details later.)
To convert USB disk/SD card/external hard drive from NTFS to FAT32, this professional partition manager can also be used as a dedicated FAT32 formatter to format SanDisk/Kingston USB drives, SD cards (SDHC/SDXC cards) to FAT32 effectively in Windows 10/8/7. This way, you can use the drive in between Mac OS, Windows and Linux freely. (Also works to format drives to other file systems.)
In Windows 10/8/7, there is a snap-in FAT32 formatter which is used often. Usually, when referring to Windows format, Windows Disk Management is a good choice due to its clear user interface and accessibility (built-in free tool).
Now we come to the end of this post. Need to format your USB flash drive, SD card or external hard drive to FAT32 with this FAT32 formatting tool? Four FAT32 formatters are displayed. Just choose one to quickly format FAT32 in Windows 10/8/7.
How to Fat32 Format 32GB or Larger USB Flash Drives. When working from within a Windows environment, you will find it is not possible to use the default Windows tools to format larger than 32GB USB hard drives or flash drives with Fat32. This is because those tools default to using NTFS or exFAT for bigger drives. In this case we need to format usb to fat32 using another utility or method. Linux users wont encounter this trouble, as the tools used there do not care what size the drive is. ;)
Modern USB flash drives are manufactured with capacities that well exceed 32GB and they typically ship exFAT or NTFS formatted. However, neither formats are detectable from all operating environments, nor are they BIOS bootable. A Fat32 filesystem can be read across most operating systems and natively supports BIOS USB Boot. So it is nice to have a method of formatting these devices using a Fat32 partition. The only real drawback to using Fat32 is that files larger than 4GB cannot be stored on fat32.
Now I need to note you can not format a Hard drive over 32GB to FAT32 unless you use one of these methods. Standard windows will not do it over 32gb. Well never fear, you basically have 2 ways to go about doing this.
I just did the same thing; I wanted to format a 500GB external USB drive to Fat32 in Windows 7, attempted DOS formatting and it started out fine, started formatting etc., but then I woke up the next day and it ended up showing me the 'volume is too big for fat32' notice, and didn't end up formatting it. So I tried the SwissKnife app (in Win7). It said right away that there were compatibility problems with it in Win7, but not one ot heed warnings, I went ahead and looked anyway, and it doesn't show the drives. So I went ahead with Acronis Disk Director and it worked perfect.
The best FAT32 formatter on Mac is the built-in Disk Utility, the counterpart of Windows Disk Management on Mac. It can format all types of storage devices like SD cards and USB flash drives to FAT32, ExFAT, HFS+, etc. Here is how to format SD card to FAT32 on Mac:
DiskGenius is effective disk partition software with which you can partition disk and manage partitions, taking full advantaging of disk space easily and safely. Meanwhile, it is a free SD card formatter and it is able to format SD cards larger than 32GB with FAT32, exFAT and Ext4 file system in Windows 11/10/8/7 and Windows Server 2022/2019/2016/2012/2008/2003 and Home Server. In addition to managing disk partitions for storage devices, DiskGenius also includes various other useful functions, such as recover lost files from formatted partition, access EXT4 drive in Windows 10, recover files from RAW drive/SD card, restore lost partitions, clone SD card, check and repair bad sectors, convert dynamic disk to basic, migrate Windows 10/11 to HDD/SSD, create/load/manage virtual disks, support Windows Storage Spaces, edit hex RAW data and more.
