I just had an idea: instead of trial and error process, which may take quite some time, what if I try to convert the 1000 books? If Calibre is not able to unpack the zip for the transfer, it should show me which one it's not able to unpack to convert. Am I right? At least, it would give me an idea of which one I have to have a closer look on.

Sees the device or sees which books are already on the device? I never faced the problem about having the device on explorer, but in fact, the sync time with Calibre took me up till 25-30mn, whereas, with my "old" configuration, it takes me 10mn.
