Ext2Fsd 0.61 was released !
Features implemented or bugfix since V0.53:
1, Ext4 extent writing support (developed by ngkaho1234 @ gmail.com)
See his repository for more details:
http://github.com/ngkaho1234/Ext3Fsd.git
2, Size manipulation and i/o path revised for support of indirect and
extent-based mappings
3, 16T volume supported (tested and confirmed with 4T volume)
Version 0.53 and previous versions only support up to 2T volume
ticket: https://sourceforge.net/p/ext2fsd/bugs/134/
4, Deletion acceleration: truncation optimized for indirect-based files
5, Size-expanding disabled in IRP_MJ_CREATE for better performance.
Windows sometimes would truncate file size back to 0
6, Support Volume exclusive-open for e2fsprogs utils. Any attempts
will be denied while EXT4 volume is being checked (e2fsck).
7, FIXME: Possible zero-content returned (requesting data from file tail)
8, FIXME: File ByteOffset updated for FO_SYNCHRONOUS_IO open (async i/o)
ticket: https://sourceforge.net/p/ext2fsd/bugs/133/
9, FIXME: don't do byte or range round up for paging i/o requests
ticket: https://sourceforge.net/p/ext2fsd/bugs/129/
10, FIXME: occasional block bitmap difference issue, cased by checksum
caculation in uninit_bg group initializing
11, e2fsprogs utils for Windows (e2fsck, mke2fs, tune2fs, debugfs) included
[the followings are change-logs made upon V0.60]
12, FIXME: Ext4 unwritten-extent supported to avoid possible data corruption
MSB of ee_len field of unwritten extent is used as only a flag. It
was mistakenly treated as extent length (block numbers) in V0.60
13, FIXME: Manually clear file to zero for indirect-block file that is newly
created but not yet written
14, Renaming supported: with names only diffs in lower or upper cases
15, I/o path revised to correctly handle ValidDataLength & unwritten holes

1, flexible inode size: > 128 bytes, up to block size
2, dir_index: htree directory index
3, filetype: extra file mode in dentry
4, large_file: > 4G files supported
5, sparse_super: super block backup in group descriptor
6, uninit_bg: fast fsck and group checksum
7, extent: full support with extending and shrinking.

9, flex_bg: first flexible metadata group

The driver may crash your system and ruin your data unexpectedly,
since there might be software conflicts and I could only test it
on some of the popular platforms. You should use it with care and
use it at your own risk!
