[XR500] External USB 3.0 HDD formated in ext4 does not show up in ReadyShare storage

Hello,

 

My external HDD (Toshiba) formated in EXT4 does not show up in ReadyShare storage. It works when it is formated in NTFS.

According to the user manual p. 121, here: https://www.downloads.netgear.com/files/GDC/XR500/XR500_UM_EN.pdf, it is supposed to work.

 

Firmware version  V2.3.2.40

 

Thanks.

    Try a different USB drive by chance? 

    When connecting it, are you rebooting the router with the drive connected then checking status?

      Could this be the cause?
      "Some USB external hard drives and flash drives require you to load the drivers onto the computer before
      the computer can access the USB storage device. Such USB storage devices do not work with the router."

      Otherwise try a different USB port on the router

        No, it is not the cause: it would not explain why it works when the drive is formated in NTFS. I tried all the USB ports already, beside, same, it works with NTFS, Fat32 and exFat. I also used a simple USB key: same behavior, it works in NTFS, Fat32 and exFat but not with EXT4.

         

        Note also the LED of the router are on when the disk is plugged so the router sees the disk.

         

        Everything points toward a filesystem support issue.

      The HDD is correctly detected when it is formated in NTFS, Fat32 or exFat and in EXT4 it works normaly when plugged on my computer.

      Exactly the same behavior with a simple USB key. So the problem is not related to the HDD.

       

      I did both: reboot before and after. I also did a factory reset.

      Hi Pixys, I've passed this to a colleague who will escalate your case to hopefully get you the support you need on the matter.

        Hello,

         

        Thanks a lot.

         

        I continued to tset and I made an interesting discovery: it works when the usb key / HDD are formatted in EXT3. It does not work in EXT4.

         

        It feels like the module kmod-fs-ext4 is missing in the Linux kernel of DumaOS...
