First 2-GB or Larger Hard Disk Can Be Formatted to Only 1 GB
Last reviewed: March 27, 1997

Article ID: Q155615

The information in this article applies to:


 * Microsoft Windows NT Server 3.51
 * Microsoft Windows NT Workstation 3.51
 * Microsoft Windows NT Server version 4.0
 * Microsoft Windows NT Workstation version 4.0

SYMPTOMS
When you are installing Windows NT using the three boot floppy disks on a computer with 2 hard disks, where the first hard disk is unpartitioned and larger than 1 GB in size, Windows NT Setup allows you to partition and format the first hard disk to only 1 GB.

CAUSE
Due to issues involving limitations at 1024 cylinders for hard disk geometry, Windows NT Setup restricts the size of the partition to 1 GB if the first hard disk is unpartitioned and there is a second hard disk available.

RESOLUTION
Before you install Windows NT, establish a partition of any size on the first hard Disk. During Windows NT Setup, choose to remove the partition. Setup will then fully partition the entire hard disk.
