    Hi!
    thank you for this project it is very nice
    but i have one question
    how i can mount an existing file to a specified partition?
    e. mount [system.img] ext4 type to z: partition
    i can do this using osfmount program after installing ext2fsd
    but how i can do this without osfmount i test “ext2mount mount system.img z:”
    it mounted and i see new partition in my computer but i can’t open it
    can tell what i need to do please

    You need a loop disk driver like osfmount or filedisk. Neither Ext2Fsd nor Window kernel support emulating a file to a disk device.

    I have a question about ext2fsd but am not quite sure where to ask it:

    Are all files written to the drive by Windows given root as the owner? Is it possible to configure a default owner for files written to the drive by a certain Windows user, or something like that? Is any sort of permissions feature planned, in any case?

    [Reply]

    Kaho Ng Reply:

    By default, all files written to the drive will be assigned with uid & gid == 0. Starting from 0.66, users may set the global access uid/gid in Ext2Mgr, and as of 0.68 per-volume setting is available. All files written to the volume will be assigned with uid/gid other than 0 if configured.

    However, POSIX ACL/NTACL is yet available currently. Implementing POSIX ACL in Windows is difficult due to incompability between POSIX ACL and NTACL (while implementing RICHACL is pretty easy). Besides, SID UID/GID conversion has to be implemented in order to implement permission management that is both Linux-and Windows-compatible.

    Same here.
    Wenn I disconnect the drive, Ext2Fsd manager starts up like a charm. But when I connect the drive and power up the PC again, the manager doesn’t do anything.
    Working on W10 x64 too

    Will version 0.64 work on W10 too? Since I read below that that is the last version that worked without problems?

    One problem with the ext2fsd 0.68 is that it disables my 2nd Optical Drive. I have 2 drives, 1 Bluray and 1 DVD burner. As soon as I put a disc in the 2nd drive, the drive letter disappears. I didn’t get this problem with ext2fsd 0.62. The only settings which I have set are ext2fsd autostart and the service manager is turned on.

    Any suggestions on a fix?

    From 0.65~0.68 I haven’t been able to open the “Ext2 Volume Manager”.

    Another Side-note, less observed: Right Click “This PC” -> “Manage” -> “Disk Management” Won’t open, just keeps saying “Connecting to Virtual Disk Service”.

    Last time “Ext2 Volume Manager” worked was 0.64, So 0.65 introduced problems, atleast on Win10 Pro,x86_64.

    I confirm that on Windows 7 64 bit too.

    anoymous2 Reply:

    And I can also confirm this, the last version that worked for me was 0.63, which I’m still using since none of the later versions works for me. Windows hangs even when trying to load in safe mode, it hangs while loading classpnp.sys according to the console. I’ve to manually delete ext2fs.sys than Windows can be started again and any version can be uninstalled completely.
    I’m running ext2fs under Windows 7 64 bit and 4GB Ram.

    anonymous2 Reply:

    Corrections: 0.64 also works for me and 0.69 hangs in safe mode while loading classpnp.sys. 0.68 does not hang in safe mode and you can at least uninstall it without the aid of a second OS or a boot cd with NTFS support.

  6. Router Gray Says:

    For people having issues with Windows hanging up or slow booting, when I had similar issues it was due to some incorrectness of the partitions or of the partition table. When I create ext2/3/4 partitions with some Windows software like PartitionWizard or Partition Master, those partitions do not load correctly for Ext2FSD, which make that the driver hangs up and interferes with getting booted and running. If I create them natively in Linux with GParted they work fine. Likewise if I create some non-Windows partition, say a raw unformatted partition for the purpose to write a CD image to it and use it as a poor-man bootable live-CD, that also makes a hang for the driver, and it doesn’t seem to matter how those are created. I have yet to experiment to try with the setting in Ext2Manager disabled of auto-assign drive letters, that might cure it in some cases, but is require that you are able to run the manager to set the setting, which means it will have to be done before such troublesome partitions exist, or by hiding them somehow that it doesn’t see them.

    I can’t launch the manager at all. When I try to launch it, nothing opens, but the CPU usage goes to 50-55% and it gets stuck there (possibly the app or driver hanging?). My computer is running Windows 10 Anniversary Update (build 14393, aka Redstone 1). It was working fine on build 10586 (Threshold 2).

    [Reply]

    Kamin4ri @ XDA Reply:

    I forgot to mention that what is using that much CPU is the kernel (“System” in the Task Manager). So I suppose it’s related to the driver.

    Hi.

    I use Ext2Fsd to mount drive attached in iSCSI to a Windows 2012 virtual machine.
    Now if I detach the driver without unassign drive letter from it I cannot launch Ext2Fsd console again.

    It is possible that some lock file exist?

    Hi,

    Thanks for this great tool! I used it on my Windows 10 64 bit system, and it works well. But I wonder if it could have a 64bit version.

    Also, I have an issue here. My EXT4 partition is on an external HHD drive connected to my system through a USB 3 connector. This connector has some kind of aggressive power saving feature that if there’s no disk activity for some time, it will shutdown the hardware. It will turn on the hardware when you try to interact with it, but will take some time to bootstrap. If this happens, the Ext2Mgr will be not responsive and even the Explorer dies…

    The connector and my HHD works well if it is connected to a Linux system. Also when it was in NTFS format, it works well with my Windows system too. So, I think the problem is caused by the Ext2Mgr or the Ext2Svc…

    I hope you guys can look into this and help me find a solution.

    Thanks~

    I’ve found a fatal combination of Windows 10 64bit Anniversary Edition and Ext2Fsd and USB rack drive. In this case I have more than one disk in a USB rack, not in raid.
    This makes Windows 10 to stop responding, practically frozen, at USB rack plugging and the boot will spin the dots forever after a reset. No repair succeeds, luckily removing Ext2Fsd files by hand would make Windows boot again. It even never gets to safe mode. Actually, Windows repair tools (PE) never finds a reason for the crash.

  11. mike Says:

    … and right after installing, before restarting, the manager doesn’t appear on screen, nor in tray, but it does something “forever”… Probably the same when at boot. The USB rack is a Lycom UB-208RM -based. It stops responding and remains in a unrecoverable state after Ext2Fsd start. It doesn’t respond anymore. I have two of these, both do the same.

    I have a feeling… The systems where drivers letters were previously assigned seem to not have this issue.

  13. Aaron Franke Says:

    Hello, I have a bug to report. Whenever any of my Ext4 partitions are corrupted, like if I held my power button when Linux was shutting down, and then I boot Windows, Ext2Fsd completely hangs the Windows background processes. I can’t open This PC, task manager opens slowly, and many programs refuse to work. However, if I restart, boot Linux, then restart, and boot Windows again, Ext2Fsd doesn’t hang anymore. Can you please fix this bug? Ideally, Ext2Fsd should simply stop trying to mount corrupted partitions after trying to a few seconds so that it doesn’t eternally hang. Thanks!

    Hello. I have a bug to report. It seems that POST version 0.62 of the driver, I have been unable to mount my two partition (Ext3) USB device. Version 0.62 has worked without any issues, however version 0.66 and later all appear to have some new functionality that breaks the functionality that I need. Would it be possible to share the source code for v0.66 and 0.68 so that I can get a better understanding of the changes that were made?
