How can I run thorough test of a drive

Hi there

Replaced a drive yesterday, resilvered onto new drive, during re-silver had another drive error on disk pool. scary…

I now -reinstalled (physically, power and plugged data cable in) the old drive.

My pool itself after a totally shut down, plug out plug cables back in etc is not sowing any errors anymore, weird…

I want to run a test on the drive i removed yesterday, see if this is actual problem with drive or a cable problem. Suggestions.
