F5-422 5x8Tb takes forever to create storage pool

[twhite]

I installed TOS 5 on the new device and I added 5x8Tb Iron wolf disks.
I tied to create a storage pool and/or a volume a couple of times. The UI accepts my choices but I do not see any indication of the process of creating the pool. I can hear a disk activity but no feedback on the page - the storage pool says "No valid data", about 24 hours after I pressed the button.

Please advice.

is your F5-422 a newly purchased device? when?
are your drives new? have they been used in any of TerraMaster nas device?

[twhite]

Both the device and disks are brand new and purchased on Oct 11th. TOS ver. 5.0.171.
I tried to create the storage pool a couple of times and this could have contributed to the problem.

[twhite]

The disks are model ST8000VNZ04

what RAID type did you choose to create your storage pool?

[twhite]

It is TRAID.
There is something wrong with the system. I can not open Apps - I can see the icon but not the window.
It is safe to do a factory reset and install TOS 5 and then try to build the storage pool?

[twhite]

I can not reset to factory settings - I get "Operation failed - incorrect username and password" and I am sure the password is correct.
Please advise how to do a hardware reset and how to format the HDD and start from scratch.
