FCLM doesn't analyze all FCP libraries.

Final Cut Library Manager (FCLM) only analyzes some of my libraries on my 4TB SSD. Anyone else have this problem? And a cure?

I contacted Arctic Whiteness and they said they might help. A follow-up said the same thing. They need to reproduce the problem. Fair enough. They might write a special version of the app that logs more errors. Also, they might want to do a remote session on my Mac. I said yest to both. Still waiting after a follow-up a second round of emails on Sep 27, to which they replied pretty much the same thing, also saying "it's not easy at all."

So I was just wondering if anyone here has had the same problem and how they fixed it. I do not want to "throw out" my SSD over this!

Also, why is the Mac so vulnerable to external devices anyway? Do PC's have this problem? OpenVMS doesn't. Stratus doesn't. Unix and Linux, AFAIK, don't. Well, the worst I've seen on OpenVMS is a disk stuck in the MntVerifyDismount state (or something like that), or a process that gets hung. Everything else continues to work fine. But on the Mac, one of the first steps in troubleshooting is often to disconnect all of your external devices. Why is macOS so vulnerable to external devices?

I did try that here, and found that if either or both of two particular disks are mounted, some of the libraries don't get analyzed and come up with the wrong size, even on the good ones (though much fewer than on the bad ones). And on those same disks, many Final Cut libraries are not analyzed properly, coming up with a wrong size, often Zero bytes! If either of those bad drives is connected, but dismounted, everything works fine. I do not have to physically disconnect the bad drives to fix the problem. But they both have to be dismounted.

Can anyone here help?

TIA!
