Troubleshooting Storage Spaces when drive is unhealthy

Any assistance in troubleshooting Storage Spaces when a drive is unhealthy, removed properly and then the pool is no longer accessible after that? The pool is visible to Windows but I cannot access it. One drive shows unhealthy (again). Storage Spaces seems to work for me until a drive fails and then all hell breaks loose... I add a new drive and then attempt to remove the bad drive but after following the process and waiting for it to complete, the pool is not available after doing this replacement.

Sorry no one has answered your question. I just saw your post. Since I do not use storage spaces nor have any knowledge of it, I can not answer, but take a look at @hsehestedt post about his experience with testing storage spaces.
Maybe you can find some of his information helpful.
Also here is MS guide. Maybe it can be helpful as well.
