As others wrote, use the smartctl program from smartmontools. I had some
"strange" problems with a samsung drive, I bought recently. I just run
'long' smartctl tests on the drive and it would fail them. I sent the
drive back with the output of 'smartctl -a /dev/whatever' and got a
replacement from the shop.
