I already have seagate backup plus hub 8 tb ,, and before the latest firmware update of router ,, router can't recognise it ,, but after the latest update the router recognise it 

Now I bought western digital elements disktop 18 tb ,, format ntfs , gpt , and I plug it's power supply to electricity ,, and it works fine with my laptop , but router can't recognise it and give me 0 giga

  @mohamed1987 

I try to shrink the western digital 18 tb to two partitions ,, and after that router recognise only one partition 

And when I plug my hard disk to the router as one partition ntfs and gpt ,, router can't recognise it and give me 0 g ,, and for some reason when I plug my hard disk back to my computer I found some of my files and folders are missing from hard disk

I want you to make firmware update to make my vr600 ac2100 recognise my western digital elements disktop 18 tb as one partition format as ntfs and of course as gpt 

I am deeply troubled that such a simple possibility is not available in your products as my brother 5 years old linksys router can do this ،، In addition to usb 3 copy speed for 5 years old linksys router can easily give me 100 m.b per second over Ethernet ,, and this new vr600 ac2100 can't do more than 17 m.b per second

When I connet it as one partition(western digital elements 18 tb) it show me no space bar and write 0 g ,, and when connect it again to my computer I found some of my data is missing for no reason ,, here it's screen shot

And when I shrink it to two partitions , router recognise the first partition only ,, and no word about other partition ,,, here it's screenshot

,, and I have another 8 tb hard disk seagate backup plus hub ,, before latest firmware update router can't recognise it ,, but now after the latest firmware it can recognise ,, here it's screen shot

I need firmware update that increase maximum capacity of single hard disk partition router can read ,,, and if can add some speed to usb port because my max transfer speed over usb is 17 mb per second

  @mohamed1987 

This is my seagate backup plus hub 8 tb ,, was not recognised by router before latest firmware update ,, and after latest firmware router recognise it

And this is my new western digital elements 18 tb , that router can't recognise(read) it with the latest firmware update
