After upgrading from 0.68 to 0.69, certain drives would have an "unrecognized filesystem" and windows would ask me to format it. I noticed in Ext2 Volume Manager, under File system, it stated "EXT3" in 0.69, but "EXT4" in 0.68. I tested this on another Windows 10 machine, where both 0.68 and 0.69 had the same effect.

My main machine is still on 14.04 and out of curiosity I reformatted the same drive partition on my 16.04 machine and it is correctly recognized as EXT4 in 0.68 and 0.69, and able to be mounted/accessed correctly.

Since there is a workaround, so I'm giving this a low priority.

    I have the same problem with ubuntu 17.10, win10, ext4, v0.69 but when I use v0.65 everything is fine.

    I got the same problem. The hard drive was created with cfdisk and mkfs.ext4 on Arch Linux. With v0.69 the file system displayed is ext3 and I can't browse files. With v0.68 everything works fine and the file system displayed is ext4.
    But I was recently visiting a friend and used v0.69 to mount the same hard drive and there it worked flawlessly. Also if I recall correctly I even used v0.69 on my system for a time and it worked.

    The issue doesn't seem to be reproducible on every system.

    Problem still exist with new window 10 and Ubuntu installation using ext4 partition format. Am using v0.69 of ext2fsd. System has never had 0.68 installed. Old laptop with both windows 10 and Ubuntu 18.04 and ext2fsd v 0.69, works correctly.

    Hello!
    Sorry for using this old post, but i have the same problem !
    I've a Dual Boot with Windows 10 last version and Ubuntu 20.04 LTS !
    When i use Ext2FSD , it works perfectly with my external USB drive and recognized it in EXT4, but the Master partitions (/ and Home 20.04) on SDA are recognized in ext3 and no possibility to change its in setting ! (Perharps a new version (0.70) can solved this trouble) ! I use Windows only for Games and Ubuntu for all works i need ! Thanks for this program !
