Public bug reported:

Package: E2fsprogs version 1.42.8

In NTFS (and possibly other non-Linux filesystems), adding a '-v' switch
to the filefrag command gives a different result from executing the
command without the '-v' switch, for the same file.

For example:

$ sudo filefrag DSC_0466.mov
DSC_0466.mov: 1 extent found

$ sudo filefrag -v DSC_0466.mov
Filesystem type is: 65735546
File size of DSC_0466.mov is 38347615 (9363 blocks of 4096 bytes)

Discontinuity: Block 4398 is at 53184685 (was 53170096)
Discontinuity: Block 6193 is at 53276776 (was 53186480)
Discontinuity: Block 6297 is at 53289023 (was 53276880)
Discontinuity: Block 6422 is at 53344771 (was 53289148)
Discontinuity: Block 7875 is at 53369116 (was 53346224)
DSC_0466.mov: 8 extents found

This has nothing to do with file system buffers, since this file has
been on the disk for several months.

This bug report says that the problem is fixed in E2fsprogs version 1.41: https://bugzilla.redhat.com/show_bug.cgi?id=927541
but I think it has been fixed only for ext* file systems, since the problem exists with E2fsprogs version 1.42.8, with NTFS, but not with ext4. I think the problem also exists with FAT file systems, but I can't currently check this.
