Plugable doesn't recognize my disk on Xubuntu 14.04


#1

I run Xubuntu 14.04 on my desktop, and the first time I plugged a drive into the Plugable unit, everything worked fine. I am currently running two other USB3 drives, and when I turn the Plugable unit on, it does not register with my system.

Whazzup?

Hi Mark,

Thanks for posting! I’m sorry your Plugable product isn’t working as expected. I’d be happy to help!

Can you let us know exactly which Plugable product you are using? We make a few different products that allow you to connect hard drives to your system and I just want to make sure I know which one you have.

Pending that information, the first step is to make sure that the Plugable device is being detecting properly. If you haven’t already, please restart your system and once restarted make sure the Plugable product is connected, can you post the output of the terminal command lsusb?

Thank you,

Bob

As a rule I do not restart my system unless a kernel change requires it.

The product I’m attempting to use is a USB3-SATA-UASP1, s/n 1094002330067.

Tonight I plugged in the unit, connected it to my system with the provided USB3 connector, plugged in my 2TB drive and turned it on.

I unplugged the USB cable and re-plugged it in. After that:

But the disk never registered on the system as a drive unit.

By contrast, with my 1TB drive, once I turn it on, it spins up, the light flashes a few times, and all three partitions register with the system.

I need to be able to use this device with all disk drives I may plug into it, not just one it likes.

Hi Mark,

Thanks for getting back. Understood your desire to maintain uptime (my best on a personal system was 456 days) but given that we are trying to step through if a USB device is being detected a cold start is usually the best place to begin. From the output of the lsusb command it appears the dock is being detected after the hot-plug event (it is the ASMedia device), so that’s a good start.

Just so I am clear on the details, you are testing both the 2TB drive and the 1TB in the Plugable dock, and the 1TB drive is detected properly but the 2TB drive is not? Assuming that is correct for now, do you know what file systems are on the 2TB drive? It may be that the system cannot identify the file system type and as a result it won’t know how to auto-mount the drive.

One way to determine if the drive is being recognized as block device (even if it isn’t mounted) is to run the command sudo lsblk -o name,label,fstype,model,size,type

This should produce output similar to this even if the drive isn’t mounted (the forum may mangle this slightly):

NAME LABEL FSTYPE MODEL SIZE TYPE
sda Crucial_CT512MX1 477G disk
├─sda1 System Reserved ntfs 350M part
├─sda2 ntfs 249.2G part
├─sda3 ntfs 450M part

sdb 00BPVT-22JJ5T0 232.9G disk
├─sdb1 128M part
└─sdb2 Thalassa ntfs 232.8G part

Does your 2TB drive show up? Can you post the output here?

Thanks,

Bob

I have added asterisk separators for emphasis - none of them show in the display.

However, I should also note that lsblk hung until I unplugged the USB cable for the dock. After I plugged it back in and waited for the disk to come up, the above showed.

I went back to the 2TB drive and did the same thing, no response. The light goes from red to green (I think - I have trouble with those colors, but it changes). The disk simply does not register.

For contrast, here’s what I get when I use my old USB2 bridge:

I’d have to conclude that the dock is not functioning properly and a replacement would be nice if it works.

Hi Mark,

Thanks for getting back. We would be more than happy to send a pre-tested replacement dock to help rule out a hardware problem with the dock. My co-worker Gary just mentioned that you had also been engaged with him directly via our support@plugable.com address for this same issue, so to keep things in one place and prevent duplication of effort, I have taken over our internal ticket and will respond to you directly to confirm your shipping address and to get the process started. Expect a message from me shortly.

Thank you,

Bob
