Just installed new hard drive in Macbook - Should I have lost this much space?

    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.

    Do a fresh install of OS X and take out the stuff you don't need.

    There is an app which removes all the language packs. If english is your primary language, you can delete the rest and save around 2-3 gb. Also, you can unistal unwanted programs.

    I saved just over 3g. I left the architectures though.

    You also need to remember that when you purchase a 160GB drive, the actual storage space is about is about 148GB. This is because the way the manufacturers measure space is different than the way computers measure the space. The HD manufacturers count a GB as 10,000,000,000 and the computer counts a GB as 1,073,724,841.

    Drive Size in GB Approximate Total Bytes Decimal Capacity
    Approximate Binary Capacity (bytes/1,073,724,841)
    10 GB 10,000,000,000 10 GB 9.31 GB
    20 GB 20,000,000,000 20 GB 18.63 GB
    30 GB 30,000,000,000 30 GB 27.94 GB
    40 GB 40,000,000,000 40 GB 37.25 GB
    60 GB 60,000,000,000 60 GB 55.88 GB
    80 GB 80,000,000,000 80 GB 74.51 GB
    100 GB 100,000,000,000 100 GB 93.13 GB
    120 GB 120,000,000,000 120 GB 111.76 GB
    160 GB 160,000,000,000 160 GB 149.01 GB
    180 GB 180,000,000,000 180 GB 167.64 GB
    200 GB 200,000,000,000 200 GB 186.26 GB
    250 GB 250,000,000,000 250 GB 232.83 GB

    Then by the time you get the operating system on there and the software you want, it is even less.

    Actually, 149 from 160 is 11, not 21. I would have been concerned with a 21 GB loss, but 11 GB is about right. One should generally plan on loosing about 10% of the drives capacity once it is formatted.

    As for the size of OS X, if you haven't done anything with the computer yet, I would recommend reinstalling the OS, using the customs settings to deselect any language you won't need or use. That usually saves several GB. There are 3rd party applications that can do it after installation, but I'd rather not install the unnecessary languagues in the first place than have a 3rd party application muck about in my System.
