FAT32format Changelog

What's new in FAT32format 1.07

Dec 4, 2017
  • GPT support, fix for boot sector when using Windows AIK's bootsect.exe, FSCTL_ALLOW_EXTENDED_DASD_IO

New in FAT32format 1.05 (Feb 1, 2010)

  • Added support for bytes per sector values of other than 512

New in FAT32format 1.04 (Feb 1, 2010)

  • 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

New in FAT32format 1.03 (Feb 1, 2010)

  • 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 )

New in FAT32format 1.02 (Feb 1, 2010)

  • 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:
