Terramaster F4-424 - Storage pool

[Clem]

ello everyone!

I've just started my journey into the NAS (Network Attached Storage) world.
I picked up a TerraMaster F4-424 and successfully installed and initialized it with two brand new hard drives.

However, I've hit a major roadblock while trying to set up my storage, and I could really use some expert insight!

The Problem:

1. I initially tried to create a Volume, but nothing happened—no progress, no errors, just silence.
   
2. I then tried to create a Storage Pool first. This finally started an initialization process, but it stopped abruptly at 10% with a frustrating popup: "The operation completed successfully."
   
3. Despite this message, no storage pool was actually created!
   
   

The Current State (TOS):
When I checked the drive status in the TOS, it sees both of my 2 drives (both showing as empty), but only one of them is listed as "Good." The second drive has no status information at all.







My Question:
Based on this sequence of events (stalled volume creation, failed pool creation at 10%, and one drive having no status), does this sound like a TOS software/firmware issue or a hardware problem with the second hard drive?
Any advice on how to proceed with troubleshooting would be greatly appreciated!
