I got a little trouble with my NAS setup. Looks like its the mainboard, but i want to double check the HDDs as well. Now i got all seagate hdd's in my server so ofcourse I downloaded Seatools. But on my main system it can't detect the HDDs so its no point. (can see the drive fine in windows itself)

So i need some other HDD test tool thats free and good and runs on win7. Thanks in advance for any suggestions.
