Hello.
There is very strange issue here:
If the volume is EXT4 formatted in Linux without parameters (FC28), it is not recognized by ext2fsd.
If I reformat it in ext2fsd by mk2fs utility (without parameters) - everything is OK, it is recognized everywhere.
I tried to find the difference - no signs of difference anywhere...
What can I do from here?

Hi,

I was about to create a bug report linked to a previous comment I wrote ( https://sourceforge.net/p/ext2fsd/discussion/143329/thread/ae5685f415/#dd5d ).
But this ticket seems close to my observations.
You'll find details below :

There seems to be a compatibility issue between ext2fsd v0.69 and a special feature inside ext4 filesystems : "64bit".
I have made some tests on a small partition :

creating an ext4 filesystem under linux (FC30) : mkfs.ext4 /dev/sda8

reboot Windows -> "You need to format the disk in drive before you can use it"

remove "64bit" feature under linux : resize2fs -s /dev/sda8
(Pay attention using a recent version https://serverfault.com/questions/753693/remove-the-64bit-option-from-ext4-filesystem)

reboot Windows -> the partition is available through its assigned drive letter

Should I crerate a new bug report or is it OK with this one ?

Regards,
H
