Topic: Dual bay USB docking stations. (Read 10616 times)

rss · « **on:** December 05, 2016, 08:17:35 AM »

My 320L seems to see only one hard drive in my dual bay USB docking station. Is there a way to get the NAS to see both drives or is that just asking too much?

What is the Mfr and model of the dual bay docking station?
Maybe a limitation of the docking station.

Swapped drives around?

Does the docking station report both if connected to a PC?

Thanks for the quick reply. Yes, the PC sees both drives as separate volumes with a single combined USB access. I tried the ORICO 6629US3-C on my PC first and expected it to behave similarly on my NAS.

Possible that the DNS may only see one drive on the USB port at a time.

I suppose but it seems like a major but unnecessary limitation. The NAS has no problems mounting multiple logical volumes on linux formatted hard disks. I've seen it use USBDisk1_1 and USBDisk1_2 with an old disk that I took out of the NAS and used on a single bay USB docking station. It probably wouldn't take much to make the NAS see both physical drives as well.

Maybe there is something between the DNS and this docking station that could be incompatible as well. Or maybe D-Link only designed the port to detect 1 drive only. You might phone contact them and ask.

I would be surprised if the problem was unique to this docking station. I wonder if there are any others out there who have used multi-bay docking station with the DNS.

USB access to external drives via the DNS is a powerful feature which is not even promoted as prominently as it should. Windows Explorer can actually see disk drives connected to the DNS as if the docking station is directly connected to the PC instead of via the DNS. Both the PC and the DNS see the list of files on the docking station and both can move/copy files from the USB drive to/from the PC and the DNS. I was hoping a dual bay docking station would behave similarly. It's a powerful feature I wish I could still use.

I agree it seems to be a good feature however I presume the most NAS devices are main designed for it's internal drives and focus is there. The USB port connection for external is probably 2ndary and maybe used for limited reasons. The drives are the DNS are primary and full featured. Not sure if a printer can be connected to the back port or not. I know some routers support his as well. Again, limited USB port usage and not really meant for a wide array of drives. Besides, USB performance would be a bottle neck compared to the Gb LAN port.

A couple of things.
1) USB devices contain information in what passes as their firmware that indicates how the device should be attached, for example a stand alone webcam will list the camera and the microphone as separate items. While the software will integrate all the sections and windows will generally ignore the separateness in a device other operating systems generally do not and just shoe the first listed device.
2) the USB port on most small scale NAS boxes only runs a subset of the full implementation, the NAS is not a full blown computer after all, with the idea of it being available to the print server to drive USB connected printers.

With that in mind I am not surprised that only one disk is visible in a two port docking station.

Thanks. That is more or less what I would expect to see for a double bay device that does not act as a hub. Unfortunately, the USB on the NSA will only see the first device.

As I said the USB port does not support the full USB spec because the NAS is not a full blown computer and much of the spec is unneeded for what it is designed to do.

You're basically stating my reason for starting this topic. Mounting a second child hard disk on the USB port is hardly supporting the full USB spec. The NAS can already mount multiple logical volumes on a single hard disk on the USB. Why limit itself to a single 4TB physical hard disk on the docking station when it can just easily use all 8TBs?

Two things.
1) the USB port connects to physical things, be they printers, disks or thumb drives.
2) logical volumes are just part of a physical disk. Without the physical disk they do not exist.

Now getting back to your point. Apparently, for some unknown, to us, reason the developers decided to set the USB port to only accept one physical device at a time. This means that a second physical device can not be connected at the same time (my programmer thinks it was done to prevent self powered devices drawing too much current from the port). We are therefore left with being able to only use one port of a multi port USB docking station (we have also seen several instances where large capacity 3.5" drives in a self powered enclosure will not work but put them in an enclosure with an independent power supply and they work without any problems.

Sorry I and my people can't be more helpful to you in this.

I guess I will have to keep this unnecessary limitation in mind the next time I'm in the market for a NAS or the next time I'm asked for a recommendation.
