I was on tha terramaster website an under "downloas" there is no more TOS version

You can download the installation package from this link first http://dl.terra-master.com/cn/TOS_A1.0_ ... 291655.ins and select "Manually download and install TOS".

Just take a little longer to study your case, I afraid something wrong during you update your TOS. please try following:

1. pull all your drives out;
2. insert another healthy drive;
3. install again the TOS, I recommand the latest one;
4. after installation complete, pull out your drive;
5. insert your previous drives, and install the os again.

if there is still issue there, please let me know.

same error, I let it run over night but this morning, nothing changed...

The system was failed to install on your hard drive, you need to replace your drives.

it was an other empty one, not one of those 4 I had in it before.
Is it possible to load a backup file via putty?

Please format the HDD in low level format on PC first even it is empty, then use it in TerraMaster NAS.
