Yeah, if I have the stick mounted sync and always copy and delete a file, some
bytes should get flipped around regularly. *If* there is no internal wear
leveling, that is. On USB sticks with internal wear leveling, you will, from a
size of about 1 GB upwards, never (Well, perhaps after 10 years...)  see a
failure due to media wear.

For the record: My USB stick has now gone through 78560 read/write cycles and is
still happily copying.

Regards,
Jan
