We can put Hardware down low on the list as that usually damages/loses files.

2-way data sync Only mirror (1 way, a shadow of the Main only)

Network sharing / NAS. Various things need to happen in lock step. Networks can insert delays. 2 Users on a share results in Keystone Kops data. Who writes what fails. Calibre is Single User access. If you need remote access, look at the using content server. that is the way to go for remotes.
Using the OS 'copy' or Explorer to make any changes at the file system level.
you are on point, the hardware is not the issue, The lib is on a brand-new HDD

While I did not get the whole picture of the later paragraph, as far as I understood, you are saying that I might have done something that copied the eReader data to my calibre library, resulting in the metadata corruption?

About the network sharing, I only use wired connection to transfer ebooks from calibre, never used wireless connection, and I am a solo user.

The most probable oopsie that I remember doing is clicking this button. I hadn't used it in the past, but yesterday I deleted two books from the eReader (First through calibre and then from the explorer) and clicked this button. It was after this that I noticed missing books


Another major culprit could be that I use koReader and connect to the eReader while in KoReader and not in nickle (Connecting while in nickle interface) when it syncs changes after disconnecting. I just read that calibre relies on nickle's database to maintain its own database for the eReader. Perhaps that lead to database issue when I clicked that "Update cached metadata on the device" button.

Other than these two, I never interact with the library directly, just through calibre.
