Orico 4 bay HDD dock

Mon Sep 30, 2019 11:24 am

Hi all, I’m having some difficulty in setting up an Orico hard drive dock with my Raspberry Pi. The dock can accept 4x 2.5” and/or 3.5” drives, each up to 6tb. It has its own power supply, and a single USB cable. It has a clone mode, but is currently set to PC Mode, which should enable each drive to be read independently.

I am using a Seagate 5tb and a Seagate 3tb. Both are in good working order, however, when I plug both drives into the dock and connect via USB into the Pi, whichever dock slot the 5tb is connected to, a red indicator light illuminates, and my Pi doesn’t seem to be able to read any combination of drives added.

I also have a 500gb 2.5” which seems to work just fine when added alongside the 3tb. For some reason, it’s the addition of the 5tb that seems to be creating some kind of issue, but I don’t know what. Perhaps a conflict of some sort?

I have also tried connecting the 5tb into the Pi using its own caddy, USB and power supply, and the Pi will still not read it if the Orico dock and 3tb are also connected on USB, but if I plug both the 3tb and the 5tb in on their own separate caddies, USBs and power supplies, the Pi reads them both just fine!

Would be hugely grateful for any advice. Thanks in advance.

Interestingly, the dock with all three drives inserted, is recognised by a Win10 machine, with no warning lights.

Is there some kind of capacity limit per USB slot on the Raspberry, perhaps? I’m currently using a 3B+, but could an upgrade to the Raspberry 4 help things?

there is a USB device (not drive) capacity for RPi3B+, which is 6 devices only.
for the RPi4B, it goes up to IIRC 128 devices.
i've yet to try connecting my RPi4B to my 16x4TB drive cluster, as I have no spare RPi4B (yet) for testing purposes.

Ah, fascinating! Good to hear I was ostensibly on the right track, at least. I’ve picked up a Pi4B, and shall be sure to report back, when up and running. Thank you.

Sadly, no change with the Pi4. Tried using LibreElec, but exactly the same problem. Red indicator light on dock drive slot when using 5tb. Drive seems to work fine by itself, strangely enough.

Could you clarify the statement "drive seems to work fine by itself"? Do you mean you can access the drive from your Pi when it is connected directly rather than in the enclosure or that you can access the drive from a Windows PC?

Are all the drives using the same filesystem type?

Sure, basically:

DRIVES ACCESSIBLE

Dock with 3tb inserted (Pi3B+, Pi4, Win10)
Dock with 3tb + 500gb (Pi3B+, Pi4, Win10)

DRIVES INACCESSIBLE

Dock with 5tb inserted + any combination of 3tb or 500gb (Pi3B+, Pi4). Ostensibly works on Win10, though.

The Seagate drives were originally in their own caddies, with individual USBs and power supplies. Strangely, if the 3tb is inserted into the dock and then connected to the Pi via USB, and the 5tb is connected to another port in the Pi but in its own caddy with its own power cable and USB, the same thing happens and neither drive is recognised.

If the 3tb and the 5tb are connected via separate USB to the Pi, both in their original caddies, the Pi picks them up just fine.

The reasoning behind taking the drives out of their caddies, and putting them into the dock was to streamline the cabling, basically. That, and having the option of adding additional storage, if required.

Here is the dock itself...

I believe the drives are NTFS, but shall double check. Thanks again!

[Guesswork]
Was one of the large disks cloned from the other?
If so, does then UUID or other identifiers need changing, so they are actually unique?

The drives were never cloned, though it’s plausible there may be some kind of conflict. May I ask any advice in potentially changing the signatures, if required?

Sorry, I don't know the detailed procedure. But if not cloned, that is not likely to be the issue.

What does your /etc/fstab look like and could you provide the output of lsblk and lsusb with the drives in the caddy (not working) and with them connected separately (working). Could you also provide the model of Pi, exact model of HDD dock, and the the OS you are running

Certainly, but I’m not sure how to(!) Sorry to ask, but is there a tutorial that might help? I’d be more than happy to look into it, and supply that info.

For the latter info, Pi 3B+ running Kodi via Retropie, have also tried Pi4 4gb running LibreElec, and the dock is an Orico 6648US3-C. Thanks again!

Could I do this through terminal?

Absolutely. Sorry about the somewhat cryptic requests. Is hard to judge level of knowledge on a forum. "fstab" is the file that specifies what filesystems to mount at boot up and can be found in the "/etc? directory and "lsusb" and "lsblk" are commands to find out more information about devices connected to usb ports. So from a terminal issue the command

Code: Select all

more /etc/fstab
to display the contents of that file and then issue the commands

Code: Select all

lsusb
lsblk
to display the information about what is connected to the USB ports and then cut and paste the results into a reply. Wrapping the cut&paste results in "code" blocks (5th icon at the top of the reply editing window) makes it easier to read them. I am interested if it shows any differences that might explain why the 5Tb drive works fine if direct connected and seems to block everything if mounted in the caddy.

Since it's the large drives that are having trouble, I'd guess it has something to do with GPT vs MBR partitioning, and how the multi-bay doc and Pi/Raspbian interacts with them. I have a Sabrent 4 bay dock for 2.5" SATA drives that works fine with my Pi computers when fully populated with 2TB or smaller (MBR) drives (Raspbian sees all 4 drives).

I haven't tried larger or GPT partitioned drives in it.

Thank you both so much, and no worries! I’m very much new to this, so cheers for explaining so clearly.

Interesting development: I attempted slotting both Seagate drives back into the dock, and plugging back into the LibreElec Pi4 4gb... and both have been recognised!

I’ve no idea why this has happened, but it’s very encouraging.

Sadly, I’m now faced with a brand new problem. No sound is coming through. The physical setup is exactly the same as before for my Pi3B+, with the exception of the micro hdmi cable, and new power supply. Audio settings don’t look too dissimilar from before.

I was surprised that the new Pi4 ostensibly does not require mpeg2 and vc1 codecs. There doesn’t appear to be an option to change refresh rates in LibreElec, with only 60.00 greyed out.

Hope this is correct for the diagnostic...

And... with the addition of the 500gb 2.5”, alongside the Seagate 3tb and 5tb, a red indicator light on the 5tb again. :(

am beginning to have reservations about using HDD docks on the RPi4B......
not that I have future use for it.... just crossing out for future projects....

Bearing in mind that both drives weren’t reading at all when both slotted in, and now are when using either Pi, I still have hope that plugging all the drives in at once is doable.

One thing I did was wait a little longer before switching the Pi back on after first turning the dock on. I noticed, Retropie Kodi on the 3B+ doesn’t seem to recognise any external drive when plugged in after the Pi has started up. Whereas, the Pi4 running LibreElec is able to detect them, if plugged in subsequently. I also noticed a fleeting red USB service warning during booting the 3B+ that seems linked to the addition of the dock..?

I think the unresolved sound issue is somehow down to the configuration of the new Pi4, running LibreElec, which is also missing a number of display settings that I’m used to, with only limited options for resolution and refresh rate. So, for that issue, I shall hold out for the next Retropie build, which in my experience is the best for running Kodi.

Have just tried hot-swapping the 500gb (inserted alongside the 3tb and 5tb also in the dock, connected to Pi3B+), and the dock indicator light on the 5tb has not turned red as before, but that drive has basically disappeared from file manager in Kodi. 3tb and 500gb are both accessible with all three inserted. Curious.

SATA isn't hot swappable by default. I believe it can be done with proper hardware and firmware, but the dock may not support it.

As for sound, are you using HDMI-0 (the port closest to the USB-C power jack)? Pretty sure that's the default port for audio (not even sure if HDMI-1 supports audio).

Specs for the dock stated hot swapping should be okay, but many thanks for the advice. Won’t be trying that again, just in case. And yes, HDMI port nearest the power socket is being used for the Pi4.

EDIT - and now seemingly at random, the 5tb and 500gb are both readable, whilst the 3tb has vanished!
