Windows 10 - Storage Space Healthy but stuck on multiple operations

Question

I have a 2 identical disk storage space that I hadn't used in a while. Yesterday when I plugged them in, it was showing a warning on one disk (no details, just the warning icon). So, I figured I could just remove that disk and re-add it to see if it would sort it self out. However, it just got suspended in removing state. I had also previously tried optimizing the storage space thinking the error would go away. Now I find that the space is stuck on both operations I had left it overnight thinking it would just be trying to move data from the disk being removed to the other. However, the status didn't change after 8+ hrs. I plugged them in to a different machine and the status is the same.

When I try to copy files from the space to another drive, I get this error:

Here are some info that were requested in other forums that might be useful to troubleshoot:

(Disk 2 and 3 are the ones in the Storage Space)

How can I get around this issue?

Update 1:

As suggested by @shawn, ran chkdsk which came up with ended with: Stage 3: Examining security descriptors ... Security descriptor verification completed. 556 data files processed. CHKDSK is verifying Usn Journal... A disk read error occurredc0e7001c Insufficient disk space to fix the Usn Journal $J data stream.

Adding another device to the pool definitely won't fix it. Most likely your MFT is corrupted. I've seen this same thing where a corrupted MFT made the drive appear to be 200x its actual size, and chkdsk would fail as a result. You can try dumping the journal first. Run this in an elevated command prompt:

fsutil usn deletejournal /D e:

Then run chkdsk again.

chkdsk e: /f /r /x

If that works, you're fine. If not, I would get the data off, wipe it (DBAN), reformat, finally running chkdsk again and run a SMART check on it to be sure it's not dead or dying. If everything there goes well, you can re-add it to the pool.
