Error message while using Copy to Library

[BookJunkieLI]

I was using the Copy to Library (delete after copy) when I received the following error message:

apsw.CorruptError: database disk image is malformed

Since I've never had this issue before, and "CorruptError: database disk image is malformed" doesn't sound good, I didn't want to do anything before running it by someone more knowledgeable. I'm guessing I need to restore database on the destination library but I haven't even tried opening it yet just in case.

I do suspect the root cause might be the unexpected shutdown of my computer at least once while running a previous Copy to Library from the original destination library that I'm now trying to copy back to. The unexpected shutdown was caused by power to the house being shutdown by power line work I hadn't known was happening.
