Just popped a Seagate 160gb, 7200rpm drive in my Macbook, replacing the 80gb I have had since buying the laptop new last year. After running disk utility and formatting the new drive, one partition etc, I ran a clean install of Tiger. Upon the system starting up I checked the specs to make sure everything is running ok, but instantly my available hard drive space has gone down to 130gb. Profiler says the total capacity of the drive is 149gb, so can I really lose 21gb? This also means the osx install was 19gb? Was basically wondering if these figures are normal and to be expected. Thanks in advance.
