TerraMaster Official Forum

is it possible your unit and mine are using different chipsets? Mine's definitely an asmedia. It also does this wierd thing where it reports all of these toshiba 1.5gb disks that don't exist... I assume that's hardcoded into the firmware as well. # lsusb Bus 002 Device 003: ID 174c:55aa ASMedia Tech...

Hi Phil, I’m actually on a Raspberry Pi 4. So neither intel nor AMD. To the best of my ability to discern this issue is related to the firmware used on the asmedia usb chipset. Newer revisions of the chipset don’t have this problem. In theory, Terra-master could fix it with an update — but that may ...

Thanks for the follow-up, Phil. That answers the core question. The issue is the Terramaster device. Time to bin it and replace it with something that does the job without risk to my data!

Let me know how you get on with the QNAP. If it’s smooth sailing I may need to upgrade. I agree with you this unit has many fine qualities. But fundamentally a DAS must be a safe space for my data. I wish Terramasters support wasn’t so abysmal. Maybe we could get it fixed.

I’m very curious to know which model qnap you’re looking at. I’ve not been able to find anything competitively priced with 5 bays.

Hi Phil,

Sadly, no. I’ve not had a second cataclysm, but usage is low and I do still see the errors when things are happening on the drives.

TMRyan, Is this answer for a different customer? I’m not running VMWare or other virtual machine software, nor am I using a thumb drive. I have a TerraMaster D5-300C, which is your five disk USB-C product, directly connected to a Linux host. When I perform extended reading and writing operations on ...

The D5-300 IS the USB device.

As mentioned in my first post, I am no longer using RAID of any kind and have reformatted the drives.

Here's the screenshot as promised.
