If we was not using "usefree" option, FAT doesn't trust the "free cluster count" anymore. So, it doesn't update until re-count. Um.. yes, it's a bit problem. Ah.. it can fix "we can trust now"-flag or something. I'll dig it more, later. And for right now, please run "df" command, it will fix free cluster count.
