Cluster size?

A 352 byte file will occupy 1 cluster on the disk, even though is smaller 
than that. The discrepancy you are seeing may be because of this. Each file 
needs to occupy a whole number of clusters, so if it uses part of a cluster, 
it 'spills over' and is seen to occupy all of it. (or something like that)
Alternatively, use:

usedSpace = diskSize - freeSpace()
