It's hard to reconcile your two statements where you state you are accessing calibre on both PCs simultaneously and that you are "single-using".

And the result of database inconsistency can be far more serious than "probably resulting in deleting and adding a book again."

At one point while experimenting, I managed to render a calibre database unusable after adding and deleting books on three machines, vacuuming the database and then closing all instances as close to the same time as I could. I did recover most of the library by deleting the metadata.db and then rebuilding the database and ignoring the errors from having duplicate IDs.

Your computer, your way of using it. Make sure you keep your backups up to date.
