--- Comment #12 from Gleb Popov <arrowd@FreeBSD.org> ---
Bumped into this with simple

dd if=/media/NTFS Volume/4Gb.file of=/dev/zero bs=1

Interesting observation:

1. Insert the stick, mount the FS.

2. Run the command for the first time:
1+0 records in
1+0 records out
1 bytes transferred in 0.002173 secs (460 bytes/sec)

3. Run the command again:
65537+0 records in
65537+0 records out
65537 bytes transferred in 0.435892 secs (150352 bytes/sec)

4. And again:
131073+0 records in
131073+0 records out
131073 bytes transferred in 0.861837 secs (152086 bytes/sec)

5. Again:
196609+0 records in
196609+0 records out
196609 bytes transferred in 1.306456 secs (150490 bytes/sec)

6. And the last time:
262145+0 records in
262145+0 records out
262145 bytes transferred in 2.224164 secs (117862 bytes/sec)

7. Unmount, eject, insert, mount.

8. Retry the test - everything is same up to numbers.

Hope this will give a hint on what's going wrong.
