The 2GB partition limit is imposed by the maximum number of clusters and the
largest cluster size.
The size of a cluster must be a power of 2 and less than 65,536 bytes--this
results in a maximum cluster size of 32,768 bytes (32K).
Multiplying the maximum number of clusters (65,525) by the maximum cluster
size (32,768) equals 2 GB.
