Notes

• To perform this procedure on a local computer, you must be a member of the Backup Operators group or Administrators group on the local computer, or you must have been delegated the appropriate authority. To perform this procedure remotely, you must be a member of the Backup Operators group or Administrators group on the remote computer. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure. For more information, see Default local groups, Default groups, and Using Run as.
  
  
• To open Computer Management, click Start, click Control Panel, double-click Administrative Tools, and then double-click Computer Management.
  
  
• You can extend a volume only if it does not have a file system or if it is formatted using the NTFS file system. You cannot extend volumes formatted using FAT or FAT32.
  
  
• You cannot extend a system volume, boot volume, striped volume, mirrored volume, or RAID-5 volume.
  
  
• You can extend simple or extended volumes that are not system or boot volumes, as long as there is available disk space. This includes volumes created as dynamic volumes or created as basic volumes and then converted to dynamic on Windows XP Professional or Windows Server 2003 operating systems.
  
  
• If you upgraded from Windows 2000 to Windows XP Professional or Windows Server 2003 operating systems, you cannot extend a simple or spanned volume that was originally created as a basic volume and converted to a dynamic volume on Windows 2000.
  
  
• You can extend a simple volume onto additional dynamic disks to create a spanned volume. Spanned volumes cannot be mirrored.
  
  
• If you extend a spanned volume, you cannot delete any portion of it without deleting the entire spanned volume.
