Thank you guys for the interest you bring solving my issue!

Actualy I noticed one thing for sure:
I have to hdd-s in my PC, an 80GB Seagate ATA (the o.s. boot hdd) and one 1T 
Seagate SATA (only for storage), there were no problems when I used just the 
80GB neither with the 1T, I noticed only that I'm getting thouse reboots when I 
start to copy about more than 4-5GB from the 1T hdd to my laptop (on ftp). 
Maybe the hdd was too warm after copying that amount of data?

Oh...I'm drunk or something but I just noticed that my 1T was not unmounted 
properly last week and I was doing only fsck with the disk mounted so nothing 
was modified to the file system, now I've done an fsck -yf to the 1T 
(unmounted)...I got some blocks (about 300) reapaired. Maybe this produces the 
reboots, what do you think so?

I also done now an smartctl -l scttemp /dev/ad4 and I got the following result:

49 Celsius was the top of the tempature for this hdd, I think its normal.

Thank you,

That's true. People want crap, they get crap. :-)

In Germany, we only get the purest power made of highest
quality electrons, 230V 50Hz 24/7/365. :-) Note that I'm
running this power supply for more than 7 years now - the
SAME power supply.

That's right. If you have the chance, monitor your power
outlet, e. g. with a long term peak monitor or a scope
with battery backed up memory, just to make sure the
requirements of the PSU are met.
