Disk diagnostic / test software?

[stockhausen]

I trying to sort out a possible issue with a a 3.7 TB 5,400rpm WD SATA-III HDD that seems to be causing problems.
Using Speccy I can't see anything reported by S.M.A.R.T.
Can anyone suggest anything that will test and/or diagnose issues on such a drive?

Thanks.

I have also found this WebSite - https://www.lifewire.com/free-hard-drive-testing-programs-2626183 - I will have a look there as well.

Thanks again
