Hello Giovanni

There are really three answers to this question...

First, you can disable the cache before mounting by setting
dev->param.n_caches to zero. In Linux you can mount with -o no-cache.

Secondly, you can empty the current cache by using sync().

There is no way to disable the cache once a partition is mounted.

Why do you want to disable the cache? It generally provides speed advantages.
