    Win98SE is limitted to 28-bit LBA drives. I understand that the
    28-bit LBA limit is 137.4Gb.

    My hard drive is a 160Gb Samsung Spinpoint 1614N which is a bit over
    149Gb binary.

    Question: Is the 137.4Gb limit of 28-bit LBA metric or binary? I
    suspect it is metric. Am I right? Trying to work out exactly how
    much to leave unallocated at the end of the drive.

    (2 ^ 28) * 512 bytes per sector = 137,438,953,472 bytes

    Does that help?

    137 GB = 128 GiB
