Updated the Vintage Sony E-Reader guide/section, because after bloody WEEKS of frustrating experimentation, constantly corrupting my SD card, searching fifteen-year-old forum threads and trying to find workarounds and procedures for managing large book collections without, like I say, Constantly Corrupting My SD Card, I finally figured out that I've just gotta repartition the card down to 4 gigs (which is only enough for about five years' worth of reading 😥) and that completely solves all the SD card related problems lol
