    Hi all,

    I swear i've solved this before - but I can't seem to get Windows 2000 Server (SP4) to recognise a physical disk that's bigger than 147gb.

    I've enalbed the 48bit lba addressing in the registry and my BIOS sees the drive as 160GB (which it is) so my mobo definitely supports 48 bit addressing.

    What else do I have to do? :duh:

    I'm using win2k server for SQL Server 2000a if anyone is wondering why I don't just run XP+SP2 :)

    Wait, I'm a complete idiot. Solved - I think? 149.05 != 147.

    A 160GB drive should be seen as about 149 (~152,000 mb), right?

    Yerp, you're right RTT.

    It's just the standard overheads unfortunately. 200GB looses around 14GB, 300GB looses around 21GB, so the 11GB loss sounds about right.

    Just a quick note to say I had a similar problem with Windows 2000 SP4 a while ago. It turned out I'd installed the updates in the wrong order, and it nearly formatted my entire media drive (300GB).

    Krikkit and psYCHopath: PLEASE READ THE THREAD.

    It has been solved a long time ago, its just the standard way drive manufacturers label the drives as 1GB = 1,000,000,000 bytes which is not the way windows reads it.

    1KB = 1024 bytes
    1MB = 1024 Kbytes
    1GB = 1024 Mbytes

    So 1 Manufacturer GB = 0.93 Actual GB

    DougEdgey, PLEASE READ MY POST! And then stop being so hostile to everyone, ffs. :\
    I KNOW that 160GiB =/= 160GB. That's not what I'm talking about.

    I'm saying that I once had an installation of Windows 2kSP4 that didn't recognise any drive bigger than 128GB properly, and screwed the drive (full of data) over.
