Thanks for you reply, Doomer.
It is clear to me that my USB box is not a quality one and a signal of this it that it was not provided with a manual, neither it is available on the web.
By the way, I am confident that it works like your and the Toshiba hard disk which we are speaking of it worked properly since some time ago when I saw the normally green led always in red state.
A proof that something is wrong with the Toshiba HDD is that I have just inserted another drive (Samsung 80GB) into the USB box and it works fine: the led is green except when it works.
Consider also that I tried to use the Toshiba HDD as the internal disk of my laptop and the led showing the activity of the hard drive was always on while it should be off or blinking when the system is writing onto the disk.
These are reasons for my doubts on the healthy of the Toshiba HDD.
Do you know similar cases?
Claudio
