Not able to continuously write to JBOD/USB/MacOS

Hi folks,

I have just received my TL-D800C and installed one Seagate Exos ST28000NM000Cdrive in bay 1 and connected it via USB cable directly to one of the USB3 ports of MacBookPro M1 2020 with MacOS Tahoe 26.2. Trying to fill the disk with zeroes, after maximum a minute copying I get this error:

1. dd failure

The log message from macOS look like this:

2. MacOS error

According to the “JBOD Enclosure Software-UG-01-en” page 2 [1] there should be a version of “QNAP JBOD Manager” software for MacOS but I could not find any in your utilities page [2] - Please let me know where I can find one. In the meanwhile I installed QNAPJBODManagerUbuntux64-1.1.0.2313 on a ThinkPad P1 with Ubuntu. The logfile shows that the QNAP connects to the laptop

On the other hand UI on the “QNAP JBOD Manager” says “The device is connected to an unsupported USB 2.0 port. Connect the device. to a USB 3.0 ot USB 3.1 ports”

4. Not connected to USB3

All USBs on the laptop are version 3.0 and higher. While trying different configurations I saw the notification “QNAP JBOD Manager Fan Error. Fan 1, Device: [TL-D800C #1: QPP2H08204]”:

5. Fan Error
5. Fan Error1920×433 66.9 KB

I tried to switch the fan settings from Auto to Max and as far as I can tell both fans are working fine.

Any ideas how I can proceed? I do not have a windows PC which I can connect to the device. I also cannot see the firmware version since I cannot connect to the device

Thanks in advance..

I will forward your issue to our internal team for further analysis. Thank you!

Could you please help us perform a test: please try connecting a Hub between the JBOD and your Mac. According to our internal test results, after adding a Hub, the disconnection issue no longer occurs during data writing.

Thank you for your assistance!

Hi folks. I had this problem a month a ago. Many things happened in that time. I am currently connecting my macos via ethernet to a lenovo laptop on which I installed TrueNAS, configured with it RAID2Z and this is how I am accessing now my JBOD. The interruption and the lack of monitoring software from your side is nott the only and not the main issue. The main issue that currently there is not viable free software RAID software. So, please feel free to close this ticket - I do not plan to write to the JBOD directly from MacOS.
Cheers
