About Ext2Fsd는 정말 어메이징한 유틸이 아닐 수 없다!
최고다!
리눅스에서 쓰던 하드를 꽂아서 정말 편하게 파일들을 윈도우로 날랐다.
러블리한 유틸리티! 아마 10만원 해도 샀을거야 ㅠㅠ
아래를 readme 파일이다. 읽고 파일을 찾는데 도움이 되길 바란다.

9, FIXME: return zero-content for sparse file gaps
10, FIXME: check available spaces before blocks allocation
11, FIXME: refresh stale root dir content after journal replay
12, FIXME: incompatible dentry management for 64k block size
13, FIXME: don't do journal replay for devices set as readonly

17, FIXME: Compiling test failure (fastio doesn't update i_size)
18, FIXME: Possible Mcb memory leak for symbolic links
40, V0.48: 2009-07-26
Modifications from V0.47:
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, Code improvements for FastIo routines and drive letter & mount
points management
39, V0.47: 2009-06-01
Modifications from V0.46:
1, Bo Branten's 5+ patches merged, lots ifstest failures resolved
2, Mount point automatic assignment for USB key and other removable
disks or removable media devices
38, V0.46: 2008-05-24
Modifications from V0.46:
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
a 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.
37, V0.45: 2008-02-19
Modifications from V0.44:
1, set hidden attribute for all files starting with "."
2, update cache window size when writing to file end
3, reaper resources allocated during file creation

2, Ext2Mgr: Added manifest to cope with UAC
34, V0.42: 2008-01-26
Features implemented:
1, Mountpoint auto mount/removal supported for removable disks
33, V0.41: 2008-01-25
Modifications from V0.40:
Bugs/Problems Fixed:

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

31, V0.39: 2008-01-09
Modifications from V0.38
Bugs Fixed:
1, Disk space isn't released after deleting big files larger than
(BLOCK_SIZE * (12 + BLOCK_SIZE/4 + BLOCK_SIZE * BLOCK_SIZE / 16))
That's 4,299,210,752 in case BLOCK_SIZE is 4096.
30, V0.38: 2008-01-04
Modifications from V0.37
Bugs Fixed:

2, Re-queue request when cache manager can't prepare pages in time
3, Possible deletion of it's hardlink entry when removing a file
4, Prohibit to create file with same names to dead symlinks
5, Wrong inode type in directory entry for symbol links
6, Possible memory leak when failed to overwrite file

miss the dirty windows with SECTOR_SIZE aligned borders
9, SpinLock related routines shouldn't be resident in paged zone
10, Possible lost of files in directory listing
29, V0.37: 2007-12-25
Bugs Fixed:

it likely happens when renaming files under subdirectory with Samba
or Linux kernel CIFS.
3, possible deadlock in renaming with simultaneous access on the same file
4, possible wrong entry (hardlinks) deletion instead of itself: it's
rare to happen but possible when renaming, moving or deleting files.
5, entry management routines enhancement
6, 64k-block support
28, V0.36: 2007-12-22

20, V0.22b: 2004-11-05
Bugs Fixed:
1, Deleting and copying files from/to a directory frequently corrupts
the directory. E2fsck will report "directory corrupted". This bug
is cuased by Ext2AddEntry.
19, V0.22a: 2004-10-28
Bugs Fixed:

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.

and Ext2QueryDirectory do a wrong way to enum entries. Thanks to
"Bomb"
4, Ext2MountVolume still returns STATUS_SUCCESS for non-ext2 volumes.

======================
Bugs
======================
(Nobody can expect that ext2fsd is bug-free.)
Any bugs, please mail to me.
======================
How to install
======================
1, Build this project, and ext2fsd.sys will be created.
2, Copy ext2fsd.sys to %system32%\drivers.
3, Import the ext2fsd.reg into your system registry.
4, After rebooting your machine, run "net start ext2fsd" at a dos shell.
5, Use mount/unmount tools to mount or unmount a disk partition.
6, You can unload ext2fsd from system with unload tool.
After version 0.10, these is an easy way:
1, Just run "Setup.bat" in "Setup" subdir for the first time. Then just
run "net start ext2fsd" in a dos shell to start the driver.
After v0.23, you need specify your system version:
setup 2k: to install ext2fsd for windows 200
setup xp: to install ext2fsd for windows xp
2, Then you can mount the ext2 partitions without rebooting.
======================
How to uninstall
======================
1, Just run uninstall.bat in the Ext2Fsd.zip package.
.OR.
2, Use the "Add/Remove Programs" in "Control Panel", click the item of
"linux ext2 file system driver" to remove the program.
.OR.
3, Manually remove the ext2fsd projects files.
a) Remove the registry: HKLM\...\Ext2Fsd & Uninstall ...
b) Remove Mount.exe/Mke2fs.exe from $(SystemRoot)\system32
c) Remove Ext2Fsd.sys from $(SystemRoot)\system32\drivers
d) Remove ext2fsd.inf from $(SystemRoot)\inf
======================
Writing support
======================
Two ways are optional to enable writing support.
1, Change the value of "Parameters\WritingSupport" in ext2fsd.reg to 1, then
import the reg file into system registry.
Or modify the registry directly. Like this:
-------------------------------------------------------------------------
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Ext2Fsd\Parameters]
"WritingSupport"=dword:00000001
-------------------------------------------------------------------------
Notes: Reboot is need.
Or
2, Change the definition of EXT2_READ_ONLY to 0, and recompile ext2fsd, then
overwrite the original one. (See line 27 in ext2fs.h)
Please refer FAQ.txt for more information.
