Random disk write out? Not possible... Apart from an alien hackerised
program. I can't deny any port above 1024, for these ones must be
available for any user. Secondary, if I did that, I could'nt even keep
connected to the net. Anyway, these ports are not dangerous, since by
definition, they don't involve internal services on my machine, such as
those below 1024 do. Apart from that, all my ports below 1024 are denied.

Hi Martin
From today, I'll try to keep a look at the HD behaviour, and keep being
careful of any intrusion attempt in my machine.
Don't worry, be happy!
Best regards,
