Drivepool lost drives, and when adding them back into the pool, files aren't accessible. Possible drive failure?

Question

So I just moved, and I powered down an always on HDD enclosure that contains 5 disks pooled together using Drivepool. When powering it back on at the new place, there was a bad buzzing noise for a couple minutes, then it went away. I checked my Plex, and everything seemed to be working well, and I used Plex with no issues for a week or two. 

Now I’ve got issues. Plex was showing files as Unavailable, so I open the Drivepool app, and it wouldn’t launch. It was stuck on an infinite loading bar, displaying “Connecting to Services”. I found the same thing when I tried Stablebit Scanner. 

After reinstalling Drivepool, it launched. However, all of the disks have changed drive letters on their own and they were all showing as disconnected in the “Pooled” dropdown. They were also showing up in the “Non-Pooled” dropdown. When browsing the files in my pooled virtual drive, the movie folder is only showing ~700 files instead of ~2200. These 700 files must be on the one HDD that is mounted in my PC and not in the enclosure, as I turned off the enclosure and clicked into various files, finding they were still intact. TV series folder is the same. 

So, I removed drives J through M from the pool, then added them back into the pool. Nothing has changed – still missing a ton of files while browsing, and Plex is still showing most things as Unavailable. 

When looking at the properties of the virtual pool, it clearly is detecting all of the drives. 56 TB capacity is correct, and 43 TB is used, which sounds about right, so it appears all of the data is still there. When looking into the individual HDDs, two of them are showing a poolpart archive as well as the poolpart file folder. I can browse them and access those files (hooray!). However, 3 of the drives show nothing in their poolpart file folders, and one of these three doesn’t show a poolpart archive.

Are 3/5 of my enclosure drives dead? Anything I can do to access that data for recovery? Anything I can do to get Drivepool to recognize the data that’s still there and get back to where I was with everything intact and in its right place? What should I try for next steps?

When browsing the physical drives, are you using the options to show both hidden and protected system files/folders?

In-use poolpart folders are (or should be) set to hidden, ex-poolpart folders are (or should) not, but if Windows has done a chkdsk repair there may be files/folders set to system.
