Features implemented or bugs fixed:
1, Acronis TrueImage compatible issue solved:
Verified with Acronis True Image Home 2009. Also verified with
FreeOFTE 3.0, TrueCrypt 6.2a.
2, Driver code-signed for Vista and Server 2008
3, Bo Branten's 5+ patches merged, lots ifstest failures resolved
4, Code improvements for FastIo routines and drive letter & mount
points management
5, Mount point automatic assignment for USB key and other removable
disks or removable media devices
Features to be implemented in future:
1, EXT3 features support (journal,
htree)
2, Documents improvement: clear and
elaborate
3, Performance improvement, code
optimization
4, LVM support
5, Automatic check & update of
new versions
Since 0.38, Ext2fsd is much stable
even under heavy i/o
loads, both for reading and writing.
Performance and
stability are highly, improved especially
stability. A new
and strong era of Ext2Fsd in product shape is coming
:)

Modifications from V0.45:
|

|

Features implemented or bugs fixed:
1, ext3 journal check and replay implemented. If the journal is
not empty ext2fsd will replay the journal and make the file
system consistent as an ext2 file system.
2, flexible-inode-size supported. recent Linux are using 256-byte
inode that fails 0.45 and before to show all the files.
3, FIXME: 2 minor issues that mislead EditPlus. EditPlus is always
trying to open any file with directory_only flag set to judge
whether the target is a directory or file, when the file isn't
s
directory, the open request should be denied. But Ext2Fsd
0.45
and before doesn't. Another issue is that ext2 file time on
disk
has different precision against windows (1 second vs 100
nano
second), which causes EditPlus thinks the file is being changed.
4, FIXME: a severe bug (likely happen on win2k system) which cause
dirty caches missed and slow down the whole system.
5, many other minor changes: bulk block allocation/release, possible
inode allocation dead-loop when all inodes are used out, Ext2Mgr
win2k support, other performance improvements.
Features to be implemented in future:
1, LVM support
2, Documents improvement: clear and
elaborate
3, Performance improvement, code
optimization
4, EXT3 features support (journal,
htree)
5, Automatic check & update of

Modifications from V0.39:
|
|
|
|
Bugs/Problems Fixed:
1, Directory inode isn't freed after directory deletion
2, Retrieval pointers implemented for extents mapping
3, Correct the handling of STATUS_CANT_WAIT. Vista's Cache
Manager often fails us on PingRead when copying bunch of
files/directories from ext2 volumes, and thus it results
in zero-data-content in copied files.
4, Optimize space allocation to minimize fragemnts

Bugs Fixed:
1, Disable the partition type changing, which causes linux
could not boot
2, Add test-signature to AMD64 drivers for vista system
|
Q) How to start ext2fsd under vista AMD64 system
A) Two ways could move you to start Ext2Fsd under vista:
1, Press F8 when booting vista, and select "disable driver
signature checking", this way works if you want only to
try ext2fsd once, you also need remove it
after usage.
2, The other way is to use it in test mode:
(Run as Administrator to do the followings)
2.1, adding the Ext2Fsd.cer to system
certmgr.exe /add Ext2Fsd.cer /s /r localMachine root
certmgr.exe /add Ext2Fsd.cer /s /r localMachine
trustedpublisher
2.2, enable test signing:
bcdedit.exe /set TESTSIGNING ON
2.3, install the driver package
run setup.bat or ext2fsd install package

Bugs Fixed:
The following two bugs caused most of the BSODs about removable
medias.
1, Ext2ReadSync: Thread stack is paged out, which casues
"Event" is invalid.
2, Ext2InitializeVcb: Ext2Global->McbList is referred before
initializing.
Features Newly
Supported:
Multi codepages supported:
In registry, there's a new item named "CodePage", just change it's content to the codepage name you want to use. The codepage name is the same to linux system.
Here's the codepages list:
big5 cp1251 cp1255 cp437 cp737 cp775
cp850 cp852 cp855 cp857 cp860 cp861
cp862 cp863 cp864 cp865 cp866 cp869
cp874 cp949 cp950 euc_jp euc_kr iso8859_1
iso8859_13 iso8859_14 iso8859_15 iso8859_2 iso8859_3 iso8859_4 iso8859_5 iso8859_6
iso8859_7 iso8859_8 iso8859_9 koi8_r koi8_ru
koi8_u sjis tis_620 cp936 gb2312 utf8
If you don't specify it or make a wrong page type, system
default OEM codepage will be used.
You must re-start ext2fsd or reboot your system after your changing the codepage setting to make it work for you.

Bugs Fixed:
1, Deleting and copying files from/to a directory frequently
corrupts the directory. E2fsck will report "directory
corrupted". This bug is caused by Ext2AddEntry.

0.22a
|
Bugs Fixed:
1, Fsck error reports: "inode is in use, but has dtime set." for deleted directories. This bug caused by non-zero i_links_count of deleted directory
inode.
2, When many files (Normally > 255 files, reported by
Zhoujingg) are deleted, the dir entry may cross blocks, which will cause ext2/ext3 driver could not correctly read the directory entries.
