[ros-dev] Partition size and FAT32 cluster size?

What is the biggest partition size compatible with 4096-byte (4 KB) cluster size, cluster size being the minimum amount of space taken by a file however small?

I googled some years ago and found it to be about 8 GB, however now I wonder if that was wrong, and I can accommodate a bigger partition.

>From what I read years back, minimum cluster size would go to 8 KB when partition size goes above 8 GB, 16 GB when partition size goes above 16 GB, 32 KB when partition size goes above 32 GB, meaning a lot of disk space wasted by small files.

I believe the best file system ReactOS can use so far is FAT32, true also for FreeDOS.

My first formatting might be done from FreeBSD, NetBSD or Linux, since I don't have ReactOS or MS-Windows installation currently.
