Thank you guys for the interest you bring solving my issue!=0A=0AActualy I =
noticed one thing for sure:=0AI 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 cop=
ying that amount of data?=0A=0AOh...I'm drunk or something but I just notic=
ed that my 1T was not unmounted properly last week and I was doing only fsc=
k with the disk mounted so nothing was modified to the file system, now I'v=
e done an fsck -yf to the 1T (unmounted)...I got some blocks (about 300) re=
apaired. Maybe this produces the reboots, what do you think so?=0A=0AI also=
done now an smartctl -l scttemp /dev/ad4 and I got the following result:=
