My (Mac-Catalina) Calibre library is growing fast, requiring a move to another drive. No problem switching except that now all my carefully curated covers are replaced with the blue generic cover. I've gone through the author's checklist for this and everything seems right. Within every book's folder is a file called cover.jpg and all of the twenty or so I checked are well below the size limit. I'll post a screenshot if the option appears here under Preview thread.

I found the instruction to check something with the code but can't visualize how to do it. I'm comfortable with simple terminal commands. One thing that might be related two metadata files: one 22mb and the other 317mb. I should have saved the smaller one in case it holds the cover data but I didn't, am trying to recover it now.

Sorry this is so long. I'm longing to see my collection whole again.
