FAT 16 maxed out at 2 gig because Microsoft decided not to use clusters bigger than 32K. My first Hard drive under FAT 32 was 6.4 gig and I noted 4K clusters. When I got a 20 gig drive it had 16 K clusters. When I reformatted with a C: partition just under 16 gig My C: drive had 8 K clusters. What happens over 64 gig? If Microsoft stops at 32 K clusters again, drives over 64 gig won’t be supported. Maybe FAT 32 should be called FAT 21.
Drives over 64 gig are now being sold at popular prices, how is this handled.
You can see your cluster size by going into DOS and doing DIR/V . Your cluster size is the space allocated for a small file.

Yuo're right. You have to use two (or more) partitions.
Heh. Just brought a picture to mind. Back in the day, I had an early 8GB drive that was using FAT16, and due to cluster optimizing, I wanted a partition or two under 2GB to get smaller clusters, so I ended up with something like:
c: - 2GB
d: - 2GB
e: - 2GB
f: - 1GB
g: - 500MB
h: - 500MB
And tack this on with a secondary HDD, I recal drive letters going down to L:! Yet, I all I was about 10GB of HDD space...
So... does this mean I'll eventually end up with
c:64GB, d:64GB, e:32GB, etc. for a total of "only" half a terrabyte??
Geeze, I'm actually looking forward to that problem
