About
This is a branch of the Ext2Fsd project by Matt Wu where I try to
implement support for metadata checksums and jbd2. I have also
updated the project so it can be compiled with Visual Studio 2019
and Visual Studio 2022.
The current status of the development is that all metadata checksums
is implemented and jbd2 is ported to support 64-bit blocknumbers.
The driver is now ready to be tested!
This work is dedicated to my mother Berit Ingegerd Branten.

Test
To test this driver run the installation programs:
Signed driver for Windows 10 and Windows 11:
https://www.accum.se/~bosse/ext2fsd/0.71/Ext2Fsd-0.71-setup.exe
Signed driver files for manual install: (even ARM/ARM64)
https://www.accum.se/~bosse/ext2fsd/0.71/signed/
Unsigned driver for Windows XP, Windows Vista, Windows 7 and Windows 8:
https://www.accum.se/~bosse/ext2fsd/0.71/Ext2Fsd-0.71-setup-xp.exe
If you compile the driver yourself you only need to run the installation
program once, then you can copy your driver file over the old in
\windows\system32\drivers.
Now you can read and write ext4 filesystems using the new features
metadata checksums and 64-bit blocknumbers from Windows.
