Calibre: Database error

[dchapman]

Good day.

I was copying books to a newly created library and received the following message:
----------

Could this be a sign of a pending disk failure?

Thanks,

Looks like you were using "Copy to . . . (delete after copy)", and something went awry in the 'delete after' phase. If the books moved to the new library, no harm done.

I would run Check Library on the 'old library' and resolve any errors before copying or moving books the 'new library'.

corrupt databases can happen for many reasons from disk failure to interfering programs like antivirus/file sync. You can use the check library and restore database tools in calibre to recover from such issues.

Thanks. I ran Check Library on all of the libraries. They seem fine.

Thanks again.
