zay,
how do you know? what are you comparing its figures with? are we talking a big difference? are you aware of the different definitions of gigabyte, which can often result in people thinking they've 'lost' disk space? Eg, 60GB drive will contain 60,000,000,000 bytes (ie, 60 billion bytes). But, software reporting on that space may define a gigabyte as 1,024,000,000, 1,048,576,000 (1000 time 1024 squared) or 1,073,741,824 (1024 cubed) bytes. This last definition leaves a 60GB drive showing as 55.88GB
