Errors when writing to memory stick with dd

When I was trying to create a DragonFly Live-USBstick using
dd if=/usr/release/dfly.img of=/dev/da0 bs=1m
It kept on failing with errors several times but got "unstuck" when I
pulled out the USB stick. Finally dd worked, but only after 5 tries.

Errors were of the following sort with many repeated messages:

and more and more... until it just worked!
