Windows has no idea of how to access EXTn (Linux) file systems. As far
as Windows is concerned, inserting an SD card with EXT4 is the same as
inserting a never formatted SD card. Windows only reads FAT and NTFS cards.
Win32DiskImager
https://sourceforge.net/projects/win32diskimager/ has
the ability to read a raw SD card. One problem is that it tends to require
an identical card for writing the image because it copies the entire card
layout, and a similar card may have reserved more blocks, meaning the image
won't fit the card. (Balena Etcher is write-only, but may be better for
that operation)
