If books are failing to convert, I'm a bit surprised that they work when sent using the extended driver. I'd expect those books would have problems in them that either the driver failed on, or the reader did. I suppose it's a matter of what the errors are.

For black and white covers, you can have the driver generate and send these. Or use my Kobo Utilities to send them as a separate step.

Hmm, maybe I don't know how to use Calibre properly (and sorry for going slightly off topic!), but is there a way to call on the extended driver instead then to do the epub conversions in advance (ideally in parallel to take advantage of my multi-core machine) and save those kepubs alongside the regular epubs in Calibre so that it doesn't do those conversions one-at-a-time when sending to the device?

I was wondering about that earlier. It would need some work as this isn't callable directly. But, I'm wondering if I could do it from the utilities plugin.

Or conversely, have the extended driver save the kepub into its associated Calibre entry rather than deleting it after transfer? I know there's a setting to save them all to one directory, but then I'd have to click and drag them to their corresponding Calibre entries to store them then, wouldn't I? That'd take a while for anyone whose collections are in the high hundreds or thousands.

The extended driver has an option to save the generated file somewhere. From memory, it's a non-calibre directory. Copying those back to the library would be possible.

Really, all I want is to have to save the processing step by doing that part ahead of time so I can just skip ahead to the transferring step whenever I have to recover from a factory reset.

I think you are being overly pessimistic. I haven't needed to do a factory reset to recover from something for a very long time. And I do abuse the device. Especially the database.

But, I do factory resets frequently to test something. When I do, I backup the user partition, do the factory reset, test whatever I need to, and then restore the backup files. And I'm back where I started.

I also backup the database (see my utilities plugin). On the fairly rare occasions when this gets corrupted, I just restore the last good backup. This is usually less that 24 hours old, so I don't lose much.
