Checking status and cleaning second hand drive

[rangor gubbins]

The IT department were throwing away an 8TB seagate iron wolf red nas drive today. So I asked if I could have it.
It's manufacturing date is 2020, so not that old.
Can someone remind me what (free) software is good for checking the drive status (e.g bad sectors etc.) and also wiping it.

Perfect, thanks. I'll try seatools. Now you mention it I have used it before a long time ago
