    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.
    8, journal:      only support replay for internal journal

    Please mention your Ext2Fsd driver as ReactOS-compatible. ReactOS operating system uses your filesystem driver on daily basis.

    Thanks for Warning!

    I decided to reinstall my Debian to the last version. I read WARNING. And install new version of Ext2Fsd.
    But I have 2 Windows (for experiments), and I forgot that in the second it is old Ext2Fsd.
    So I was surprised when my fresh install had crashed.

    People, pay attention.

    Great Thanks for this software. Helped a lot in managing ext partitions. Ext2fsd seems to be the only perfect software of its kind. Please keep developing it.

    There is a bug in Ext2fsd 0.69 which is absent, say, in v. 0.52. It is not a bug, probably, it is “side effect” – to be fixed. If the driver is installed in Windows Server 2012 R2, when I use USB HDD (with 2 NTFS primary partitions, no EXT2), it cannot be parked! I.e. the drive is parked when you use “Safely remove” button in Windows notification area (the safely remove button shows that it is parked), but in fact it remains mounted in the system, and the OS hangs when I try to reboot the computer. If I uninstall the driver, everything gets ok again. I’ll check it in Windows 10 build 1709 and Windows 8.1 and report how the things are there. Of course, I’d like to use the latest version. Is there any workaround? Please, fix it!

    I’m using this tool (v 0.51) on Windows 7 for many years in order to mount my ext3 formatted HDD which is installed in my Popcorn A400 media player.

    I recently bought a new, bigger SSD drive and decided to go for Windows 10. Since Ext2Fsd 0.51 doesn’t work with Win10, I downloaded and installed 0.69. Mounting my ext3 HDD was no problem, but my whole system now crashes every time while copying new data to the drive!
    Fortunately, I kept my Windows 7 partition on the old SSD. So, as far as there is no solution in sight, I have to switch back to my “old” Win7-SSD to be able to refill my ext3-HDD.

    Thanks though for this nice little tool. I’m gonna keep an eye on its future development hoping that some day it will work smoothely under Win10.

    I think, you may use 0.52 version. It is possible to be installed on Win 10, but with a command file.
    Old versions do not have exaustive write support of ext partitions – you may write only new files, but neither delete, nor rewrite existing. Although old version will not crash Windows when unmounting mounted drives.

    Thanks for your advice! I’ll try to install the 0.52 version the next time using the described cmd line.
    But I’m not sure what you mean by “…but neither delete, nor rewrite existing”. When connected to my pc, I always DO delete some files that could not be deleted by the delete function of my media player.

    I mean this happens with ext4 partition of 64-bit Linux – such partitiona are not fully supported with 0.52 version of Ext2fsd. Although you can create dirs and copy new files to such partitions. The correct write support is implemented in the later builds of Ext2fsd. But the critical thing is to make latest Ext2fsd not hang during unmount when rebooting Windows.

    Ext2Mgr hangs at startup:

    Reverting parts of git commits d8632a1 and d570f95 fixes that issue.

    Dear Ext2fsd developers!

    I tested Ext2fsd 0.69 on Windows 10 x64 build 1709 (Creator’s Update), it works flawlessly, it is free of the bug I noticed in Windows Server 2012 R2. Please try to fix this annoying unmount bug under Windows Server 2012 R2 (see my earlier post). I guess you did not launch it in W2012R2!

    With 64-Bit mode now listed as an unsupported feature, I’m assuming 64-bit EXT4 drives/partitions can’t currently be mounted?

  9. ALEX BALCANQUALL Says:

    .69 cannot be installed due to the driver not being signed, oh well.

    0.69 doesn’t seem to work on Windows 10 x64, after assigning a drive letter to ext4 disks they show as unformatted; I hope it will be fixed in the next version

    Same here.
    I tried to mount with mount.exe running from an admin prompt and, while it said “Succeed.” the drive is actually not mounted and I’m asked to format it. The dev might have simply disabled ext4 mount due to the 64bit mode issue…

    Simon Reply:

    It seems all ext4 mounting was disabled, as I experienced similar occurrences on 32 bit machines, showing ext4 partitions as ext3.

  11. Simon Says:

    I’m not sure if it is a bug, or if I’m just too stupid to use the program: the 0.69 version doesn’t recognize Ubuntu ext4 partitions as ext4 but as ext3 and consequently windows complains about the drives not being formatted.

    It would be helpful to mention Ubuntu/Fedora/Mint versions rather than ext4 or 64 bit…

    Ubuntu16.04 LTS is ext4 64 bit….
