I think that Snow Leopard installed only some of the printer drivers, and was generally a smaller OS than Leopard. Also: Snow Leopard uses 10-based kilo/mega/giga whereas all earlier OSes use 2-based. This means: Old OSes 1 KB = 2^10 bytes = 1,024 bytes 1 MB = 2^20 bytes = 1,048,576 bytes 1 GB = 2^30 bytes = 1,073,741,824 bytes Snow Leopard and Disk Manufacturers: 1 KB = 10^3 = 1,000 bytes 1 MB = 10^6 = 1,000,000 bytes 1 GB = 10^9 = 1,000,000,000 bytes So... even without the smaller OS, your old 58GB would have become a little over 62GB just because of the new accounting.
