There may be differences due to the definition of a gigabyte (i.e. 134217728 bits vs. 125000000 bits) where manufacturers prefer to choose the smaller conversion to get a bigger GB. Then there's the fact that a certain percentage of any media will be reserved by the filesystem format. This is true with hard drives, blank CD-Rs, blank CD-RWs, blank DVD-Rs, blank DVD-RWs, flash drives, etc. These differences exist on all platforms; it's not a Mac-only issue. -- Eugene Lee -- G-Books is sponsored by <http://lowendmac.com/> and...
