Asus AC88U - Hard Drive Woes

[Nick Darley-Jones]

Good afternoon,

I've purchased a Seagate 6TB USB drive but I'm having real problems with it when trying to use it in conjunction with my router/pc.

The first issue is that I cannot format the drive into one which both my PC and Router recognises. If I use the router and use NTFS format, when I plug it into my Windows 10 PC it cannot see the partition and states it's formatted with MBR. Windows will only allow a 2TB partition when using MBR.

If I format it with GPT I get the full 6TB, but then the router won't recognise the drive or allow you to write to it. The strange thing is that I have another 8TB Seagate drive using GPT and that works? Can anyone recommend a format I can use on Windows which will allow me to use it on the router (of visa-versa)?

The second issue is speed. I'm running firmware 3.0.0.4.384_21045. I can only get a maximum of 25mb/s write PC>Router and 28mbps (Router>PC). I've noticed the Reduce USB 3.0 Interference has gone and now replaced with USB2 or USB3 modes. Am I pretty sure I should be getting higher than this?

I have not tested with older firmware just yet.

Kindest regards,

Nick

Hi, it looks as if your drive is running at USB2 speed, either because it is set so in the GUI, or bacause of a bad connection or too much interference. Note that I am assuming you are measuring 25MB/s through a network cable connection (not wifi). Try to use another USB cable and / or verify it can run successfully at USB3 speeds when connected to a PC. Besides, note that the max documented supported size is 4TB (although there are reports of bigger sizes working w/ASUS routers).
The other suggestion is to make sure that you fdisk and format the drive using the router (not a PC).

I've noticed the Reduce USB 3.0 Interference has gone and now replaced with USB2 or USB3 modes.

This is the exactly same "feature", only on another position, reduce interference actually means downgrading to USB2.0!
