# Extending a partition on a logical drive

(Microsoft® Windows® XP, Windows 2000, and Windows NT® 4.0 only.)

If you have increased the size of a logical drive, you can extend the partition on that logical drive to use the newly added space.

Notes:
  1. To complete this procedure, you must be logged on as one of the following:
     - An administrator
     - A member of the Administrators group
  2. If your server is connected to a network, network policy settings might prevent you from completing this procedure.

## Windows 2000 and Windows XP

1. After completing "Increase logical drive space," shut down and restart the server.
2. In the lower-left corner of the desktop, click Start Programs Administrative Tools Computer Management. The Computer Management window opens.
3. Right-mouse click the volume and click Extend Volume.
4. Follow the Extend Volume wizard instructions.

Notes:
  1. You cannot extend the following types of volumes:
     - Striped
     - Mirrored
     - RAID level-5
     - FAT or FAT32 format
     - System
     - Startup (boot)
     - Simple or extended volumes that were upgraded from basic to dynamic.
  2. You can extend a volume only if the volume is formatted using NTFS or does not contain a file system.
  3. You can extend a simple or extended volume only if the volume was created as a dynamic volume.
  4. You can extend a simple volume if the extension will occur within its original physical drive or onto additional physical drives.
  5. After a volume is extended onto multiple drives (spanned), it cannot be mirrored or striped.
  6. You can extend simple and spanned volumes on dynamic disks onto a maximum of 32 dynamic disks.
  7. After a spanned volume is extended, you cannot delete any portion of the volume without deleting the entire spanned volume.

5. Click OK.
6. Right-mouse click the volume and click Commit Changes Now. A confirmation window opens.
