[Help] D6-320 disconnects

Posted: 11 Nov 2026, 22:18

I recently bought a Terramaster TDAS6-320 for my homelab as a storage unit for my NAS. I connected it over USB A to C on my Minisforum MS-01. The minisforum is running Proxmox 9.2.26.

The enclose currently contains 4 disks. of all 4 out of the 2 lights 1 is on and every few seconds the 2nd light turns on of one of the bays (top row, most right), however after some time it moves to another drive and back and forth.

Quircks are active, instead of uas it is using usb-storage
Running on Linux proxmox03 7.0.14-28-pve #2 SMP PREEMPT_DYNAMIC PMX 7.0.14-28 (2026-11-02T11:54Z) x86_64 GNU/Linux

...etc.. For all 4 drives

I have a virtualized Truenas SCALE (goldeneye, up to date). the 3 large disks are part of a ZFS pool, the small one is a single pool.
Disks are passed through based on their ID.

Code: Select all

qm set <vmid> -scsi4 /dev/disk/by-id/ata-WesternDigitalRed12TB,serial=serial
Then, I believe as part of a scrub, high intensity traffic of 250Mb per disk, something happens that causes the disks and terramaster to disconnect and truenas losing their disks. On the proxmox I see this in the logs:

Nov 11 14:46:36 proxmox03 kernel: usb 4-1-port4: Cannot enable. Maybe the USB cable is bad?

Nov 11 14:50:13 proxmox03 kernel: usb 4-1.3-port1: Cannot enable. Maybe the USB cable is bad?

I've already updated the firmware as per your instructions.
cables used are from Terramaster
Please advise.

First, you need to rule out whether the USB ports on your Minisforum host can provide a stable connection. We have received multiple reports indicating that on certain models from Minisforum, Beelink, and GMKtec, USB connections become unstable under high load. To verify, you can connect the D6-320 to a Mac or to a host from brands such as Dell or Lenovo and see whether the issue persists.
