tested hot swap, now drive is in predictive failure

I have a DL360 G6 (yes I know). I decided to test hot swap and replaced a drive with another one. THe other one failed, so I put the previous working drive back in. It's now in "predictive failure" mode for that bay.

Is there anything I can do to fix this? Did hot swap damage the drive?

I am not panicking, there wasn't anything on these drives that was dramatically necessary.

You have a failed drive and a failing drive. Replace both.

Storage media wears out relatively quickly, even when handled properly. And if these drives are the same vintage as the server they are aging.
