AVD is likely getting at the fact you have no real idea how long the drive has been used nor in what capacity. HD Tune Pro would be a good thing to run to at least get a snapshot of the hours it has been powered on but it leaves a lot of variables to the unknown. The drive could last 4 years or 4 days.
All in all, it's a gamble.
by the time you run HDtune, it is already bought, so it is too late.--

google this "(sqrt(cos(x))*cos(200*x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01, sqrt(9-x^2), -sqrt(9-x^2)"
