@Gheesh sync is not enough to "safely remove" the device. You must unmount it, otherwise the FS may still be in not a good state after removing. In the best case on replug the FS driver will just reset the "unclean unmount" flag and replay journal if any, but in the worst case data may be corrupted, since you never know what happens between return from sync and unplugging.

@EverythingRightPlace sync works from any user.

This is only possible as root. Isn't there a possibility for the standard user? I think sync flushes all system buffers. Is this even necessary?
