Format FAT32 partition with set “Allocation Unit Size”
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;

Note: This answer didn't work for me.
I wish to format a FAT32 partition with set AUS of 32K. I've read the man page man mkfs.fat, and the only thing that I can find is
-S LOGICAL-SECTOR-SIZE
Specify the number of bytes per logical sector. Must be a power of 2 and greater than or equal to 512, i.e. 512, 1024, 2048, 4096, 8192, 16384, or 32768.
I don't know whether this is the "AUS", but I tried it out, and set -S 32768. This happened:
user@pc:~$ sudo mkfs.fat -S 32768 /dev/sdb1
mkfs.fat 3.0.28 (2015-05-16)
Warning: sector size is set to 32768 > 4096, such filesystem will not propably mount
WARNING: Not enough clusters for a 32 bit FAT!
mkfs.fat: Attempting to create a too large filesystem
I also tried sudo mkfs.fat -I -S 32768 /dev/sdb if that works, and it doesn't. Same error prints out.

man mkfs.fat:
-s SECTORS-PER-CLUSTER
Specify the number of disk sectors per cluster. Must be a power of

The allocation unit size is also known as the cluster size.

Tried that out. I want 32 KB clusters, and 1 sector is 512 bytes. Therefore, I set-s 64. But I triedblockdev --getbsz /dev/sdb1, and 4096 came out. What does this mean?
