open("/dev/mmcblk0p3", O_RDWR)          = 3
read(3, "\353X\220MSWIN4.1\0\2\10\6\0\2\0\0\0\0\370\0\0>\0i\0\0\0\0\0"..., 512) = 512
lseek(3, 0, SEEK_SET)                   = 0
write(3, "\353X\220MSWIN4.1\0\2\10\6\0\2\0\0\0\0\370\0\0>\0i\0\0\0\0\0"..., 512) = 512
close(3)                                = 0
It changes bytes 490-494 not sure how significant those are for FAT32.
Do you know what it is writing there? If I remember correctly, "pickel should-factory-reset" is checking for failed boot-to-nickel. If this fails four or five times, you get prompted to do a factory reset. pickel should be checking something that nickel sets if it starts successfully. I've always assumed that nickel sets it to zero and pickel reads and increments it each time. But, accessing it like that is pretty crude. If they were writing somewhere that wasn't previously used, then that might explain what's happening.

But I thought the Windows detection problem was different and also affected some other devices. Oh well, if formatting really solves it, that's fine too.
I think it's changed from the preview. When I tested on an old laptop, Windows 10AU wanted me to format the Kobo device. Calibre actually found the device but complained it couldn't access the database.
