    Up to about 3 years ago, I ran a 1TB drive as network drive on my RT-AC66U, but I gave up after some months because of poor performance. I just installed a new (empty) POWERED 4 TB drive (200 MB left unallocated), formatted NTFS, and the drive is recognized, but stays listed as Unmounted. This is a common issue and I have tried all solutions that are given in this forum, without success. The only thing that I haven't tried is the mounting in Linux.
    The router has the latest Merlin 380.70 firmware installed.

    The router log:

    I have talked to the Asus tech support, and for them the router can recognize up to 4 TB drives, and according to them there shouldn't be any issue.

    I would appreciate any help in getting this drive to mount. I was planning to upgrade to the AC88U, but this router has the same ext disk specs as the AC66U. Do I have to change router brands in order to be able this 4TB network drive?

    Thank you very much

    The idea that this router should be able to handle a full 1TB drive as a "just like NAS" is just not the case. Asus is right it will recognize the disk but what it does with it is another thing. Keep in mind the idea of the USB drive mounting on a Asus router is for low usage households. Also applicable here is the version of Linux on these routers. A NAS is the way to go. :)

    Thanks for the comment, and I do have 2 Synology NAS on the network (412+ and 212+). The USB 3.0 port is however too slow, and I was hoping that by connecting the drive directly to the router, I would have optimum speed. Do you for example, have similar issues with your RT-AC3100 ?
    The goal of this 4 TB RAID HDD was providing for a network (5 PCs) backup option.
    Is this only an Asus deal, or are there better routers available that would be able to handle fast access, without drive size limitations?

    If it's a new drive, it might have some custom partitioning from the vendor - need to wipe the partition map, create new volumes, and then you can mount it...

    Anyways - the NAS that OP has (@george13 ) is going to be a better option to connect the drive and share from there vs. trying to share from the Router/AP - better code, better security.

    Thanks. I did wipe the drive completely, created new volumes, and there is now only the 200MB unallocated, and the 3.8 TB partition. But, Asus cannot mount it. So, if I understand correctly, the Asus cannot function as a true file server?

    Create the volume and format it on the AsusWRT device... you'll have a choice of ext or ntfs - I suggest ext, but ntfs has benefit if you want to move a device back to a windows box...

    It's a router first, security being paramount.
