You receive a "There is not enough space on the disk" error message when you copy files to or install updates to a partition

When you copy files to or install updates to a partition that has 512 megabytes (MB) or less of free space, you may receive an error message that is similar to the following:

This behavior occurs because Service Pack 4 (SP4) for Microsoft Windows 2000 increases the size of the reserved space that the update sequence number (USN) journal uses on your computer when you install the File Replication service (FRS). The size of the reserved space that the USN journal uses increases from 128 MB to 512 MB when you install the FRS.

Note The USN journal is a fixed-size log that records all changes that occur on partitions that are formatted with version 5.0 of the NTFS file system. The disk has reserved space to hold the size of the USN journal, but this reserved space is not incorporated in the display of available free disk space.

To resolve this behavior, use the Fsutil.exe command-line tool to decrease the size of the reserved space that the USN journal uses. You can install Fsutil.exe by using a Microsoft Windows XP CD or by using a Microsoft Windows Server 2003 CD.

Note If the FRS has a Sysvol share on the partition, move the share to another partition.

To decrease the size of the reserved space that the USN journal uses, follow these steps:

1. Click Start, and then click Run.
2. In the Open box, type cmd, and then click OK.
3. At the command prompt, type fsutil usn deletejournal /D VolumePathName, and then press ENTER.
   
   Note VolumePathName specifies the drive letter followed by a colon, the mount point, or the volume name.
4. At the command prompt, type fsutil usn createjournal m=0x800000 a=0x100000 VolumePathName, and then press ENTER.
   
   The size of the reserved space for the new USN journal decreases to 128 MB.
5. At the command prompt, type chkdsk /f, and then press ENTER.
