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 2017 and Visual Studio 2019. This is work in progress. If you need a stable driver you should get the latest official release from http://www.ext2fsd.com. If you want to try this branch you should still install the oficial release and then copy this driver over the old in \windows\system32\drivers. The current status of the development is that metadata checksums is implemented but there is an calculation error in the inode checksums that must be investigated before I start with jbd2.
