Setup Changes Drive Letters After a Partition Is Deleted and Reinstalled

ID: Q225025

SYMPTOMS

If you delete a partition during Setup, create a new partition using the new unpartitioned space, and then install Windows 2000 in the new partition, Setup may change some of the drive letters on the computer.

For example, assume you have a computer with one hard disk and two partitions, drive C and drive D, and a CD-ROM drive E. If you then delete the drive D partition during the Windows 2000 installation, create a new partition using the new unpartitioned spaced, and install Windows 2000 in the new partition, when Setup is finished you may find that Windows 2000 was installed on drive E and the CD-ROM drive has become drive D.

CAUSE

This problem can occur if you boot from the Windows 2000 CD-ROM or from the four boot floppy disks. When a partition is removed that holds a drive (logical or physical), Windows 2000 reassigns those remaining drives lettered after the deleted partition, and assigns the next available drive letter to the new partition.

RESOLUTION

To preserve drive lettering, deleting the appropriate partition and then re-create it outside of the Setup process. You could do this in a previous operating system, or by using a boot disk with partitioning software.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

The drive letter of the drive that was deleted is assigned to the next available drive and the rest of the drive letters are moved up. This includes removable media.

If the hard disks in the computer do not have any defined volumes, a removable media drive may be assigned as drive C, and the CD-ROM drive then becomes drive D. A CD-ROM drive does not become drive C even if it is the only defined drive in the computer.
