error code 0x80780119 not enough disk space to create shadow copy

A Workaround Without Repartitioning:

When trying to make a system image of Windows 7, I got error 0x80780119.  After searching this thread (plus others), I found my 100 MB System Reserved partition had grown a large USN journal.  I assigned it drive letter F:.

Fsutil usn queryjournal F:

Then I ran this command to clear and disable the USN journal on my System Reserved partition:

fsutil usn deletejournal /N /D F:

This freed 48 MB.  The USN journal on my System Reserved partition remained disabled after a reboot, which I verified by re-running the query.  Subsequently, I was able to make a system image without error.
