I am using the Asus RT-AC3100 Router as the the device for attaching a USB hard drive to hold our home network backup files.
Currently, I have a 2 TB WD My Passport formatted with the EXT4 Linux file system. Works great.
As the 2 TB My Passport is getting a bit full, I decided to get a WD 8TB Elements .
I formatted it to the Linux EXT4 file format. Attached it to a regular desktop system. Everything appeared to work correctly, at that point.
However, when I attached the 8TB Elements to the USB port on the Asus RT-AC3100 Router, it failed to mount. My WD 2TB My Passport does mount automatically, as expected.
Surprisingly, when I formatted the 8TB Elements back to NTFS, it would mount. But that is not the configuration that I am after. Considering that the My Passport works with the router using EXT4, the normal expectation would be that the Elements should also work. Firmware flaw?
Is there a known reason for this failure?
PS: As a quick note, Linux does not even appear on the drop-down lists for this website as an operating system. I hope that WD will recognize that and add support for LINUX. Hardware, such as disk drives, should work under all operating systems.
