Hi!

Yeah the info i gave was... minimalistic, to say the least...

So, my HDD is a Western Digital Red 3.5 4TB 5400rpm 64MB SATA3 WD40EFRX

It is connected via an external HDD case, with separate power supply.

When i connected it to my PC, it was recognized as 3.6 tb storage. I formated it in NTFS.

I tried to create a folder called "sda1", and put some files there, but still it says no disk found.

I checked, and when i connect the HDD to the router, the USB led on the router flashes a few times, then lights up continuously.

I appriciate the help!

Hello there!

Maybe this can give you even more information: https://imgur.com/a/qV12EGD

This is the exact HDD i would like to connect to my router.

Thanks for helping me out.

So i got an HDD case like this: https://images-na.ssl-images-amazon.com/images/I/51rda01PfZL._SL1000_.jpg

It has its own power supply, and it connects to the router via a male-to-male USB Type A.

Everything is the same as with the 1tb drive, except it does not recognize the 4tb drive now...

@QuinnHUN I hFve the same issue you have (same HDD brand, same basic specs, 3TB instead of 4TB).

Did you ever find a solution to this USB shared drive connundrum?

In my case a 500gb drive (tiny, I know!  (Funny to think on my first IBM AT 286 (yes, I am older than dirt) I paid $400 extra to upgrade from a 10MB(!) drive to a 20MB, "So I would NEVER run out of storage!")) works perfectly fine in the same drive caddy when connected to the C1200.

But, when I insert the 3TB drive in that same caddy no drive is found.

Using the same drive caddy and either the 500gb or 3TB drive connected via USB to a PC or laptop, both drives work just fine (so I know the caddy is working fine and both drives are formatted correctly, etc.)

I hate the thought of wasting time and money to replace an otherwise perfectly good working wireless router just to make a larger drive work properly (assuming newer models from TP-Link work properly with a 3TB or larger HDD).

Thanks,

Duane

@QuinnHUN 

it seem to be a problem with all the TP-link routers supporting 4tb hhd. i have a AX50 that works with 1tb but not 4tb.

I have an external drive (2TB WD7200 Blue) that has just about filled up.  So I purchased a 4TB WD7200 Blue to replace it.  In my powered external USB case, both drives are functioning perfectly in the same external drive case by both USB 3.0 and 2.0 (not that I would use USB 2 for copying, but in order to troubleshoot later, I confirmed this) plugged into my Windows 10PC, yet the 2TB drive worked perfectly, the 4TB would not even scan with the Archer C1200 router.  In spite of what the rep indicated, I suspect the firmware does NOT recognize GPT format discs, exceeding 2.2TB in size.

@Kevin_Z I have 1TB HDD of HP make, not working with router shows 0 disk but ehen I use normal pendrive it works.

Can you help to connect External HDD with router, (HDD is without external power supply)
