What to check - Buying Second Hand HDD

[patkim]

Hi, I am about to buy a second hand HDD. Have aligned with the seller that I shall also do a few checks from my side before purchase. What should I be specifically looking into e.g. any key SMART parameters. Could someone advice please. Thx

Check for 'read error rate', seek error rate, spin retry count, uncorrectlable sector count and especially relocated sector count. you can also post a screenshot of crystaldisk info.
