But then Calibre gave an error message
Spoiler:
Traceback (most recent call last):

MemoryError

which I had time to copy before it closed itself off.

I don't understand what is going on.
That is an error writing the metadata.calibre file to the device. If this is with the 32bit version of calibre, it means the amount of data in the metadata for all the books is very big. This is the metadata for all the books on the device.
