I just installed a new Maxtor 120gb hard drive. Installation seemed to go okay, but when I go to My Computer, it says the total space is 114gb. On my 20gb drive, the total space was 18gb. I assumed the "lost" 2gb was for formatting info, partition info, etc. But why am I missing 4gb now? Is it just that higher-capacity drives take more space for partition/formatting info?
