SUMMARY

When you use Disk Administrator to change the drive letter of your system or boot partition, important references to the drive (such as drive paths, system environment variables and system-controlled references for the system or boot partition) are reset. You need to reset the following user- controlled references manually (either before or after changing the drive letter):

  • Paging File drive designation
  • User environment variables
  • User set program items

MORE INFORMATION

If you do not move the paging file before you change the drive letter of the partition that the paging file resides on, the following error message appears when you restart the system:
Limited Virtual Memory Your system is running without a properly sized paging file. Please use the virtual memory option of the System applet in the Control Panel to create a paging file, or to increase the initial size of your paging file.
To correct this situation, re-create the paging file under the new drive letter designation.

You do not receive any errors or experience problems running applications that access the user environment variables until you attempt to access those resources. You can change the user environment variables by running Control Panel and choosing System. Each program item affected by the drive letter change must be modified individually.
