TerraMaster Forum

Hello, I think I've found a solution for the issue where the D4-320 will not initialize a disk in some or all of the bays.

In my case, bays 1-3 were working perfectly fine, but bay 4 would not detect a drive unless I first performed the firmware update as described in this post: viewtopic.php?t=7111

However, whenever the D4-320 would go into suspend if I restarted or shut down, it was as if the firmware became corrupted and the drive would no longer be recognized even though Windows could see the controller. The only way to get the drive to initialize was to perform the firmware update again after every boot.

I did some research on the controller and found a different firmware version that does not have this issue: 220906_D1_45_01

Not only is bay 4 now working correctly on every boot, but R/W performance is slightly higher:
210830_D1_63_F7 (from forum) - 250/244
220906_D1_45_01 (new) - 256/246

The only downside I've found so far is that the bay indicator LEDs do not work with this firmware.

Perhaps TerraMaster can investigate why this firmware solves the initialization issue and merge it with the firmware meant for the D4-320?

Thank you for your feedback. We have already forwarded this issue to the relevant project team.

Are there plans from the project team to release new firmware to resolve this or is it a hardware defect?

I also found another bug with the released firmware (210830_D1_63_F7): If bay 1 is not active during a cold boot, sometimes the fan never turns on.
