My hdd is doing things with the hdd when I am doing things that don't require hdd usage like going into menus. I have attached my voice file. I think this is the problem. No more logical reason.
This task depends upon

Perhaps the HDD spins up because some glyphs need to be read from the font and stored in the font cache. his will happen every time a previously unused character is being printed (unless the whole font fits in the font buffer). If you are using the Chinese language file this can happen a lot.

Could this be the explanation for this problem?

We could try to solve it by pre-loading every character used in the language file (and maybe the database as well)

Marcoen: I've been thinking that language files should include a string (generated by genlang) of all characters used. Which will make your suggestion easier. It would also make it possible to check when loading a new font, if that font supports the current language, and you could inform the user gracefully.

that wont help because it shuold dump out the LRU gliphs which means if its spinning up all the time the cache isnt big enough

FWIW, this is probably a duplicate of  FS#8397  and  FS#8429 . A significant number of people (including myself) have been reporting this issue in Flyspray and in the forums.
