[Help] Re-Initialization of F4-212 NAS without formatting disks

[gizmo112]

Hi there

After a network and router switch I was at first not able to get back into my Terramaster F4-212, updated TNAS software (MAC) and finally was able to find it. However, I am forced to initalize it from scratch and during wizard it gives me a warning that all data on the drives are going to be deleted, which I want of course to avoid as I am having data on it.

The Gui does not provide any option to elsewise log-in or authenticate. How can I get still back into the system to access my data? A step by step guide or any point to an existing forum article would be appreciated; couldn't find something myself which suited my case.

P.S.
With support I was in touch over Chat and we tried to get root access via terminal but I was not able to finish procedure and needed to abort it due to time constraints.

Please try Method B:

1. Power off your TNAS device.
2. Remove all HDD/SSD.
3. Power on your TNAS.
4. Wait about 2 minutes until the network light is active, then use TNAS PC to search for your TNAS.
5. Clear your browser cache.
6. Select the device and click "Login" to enter the initialization page.
7. When the system shows “No hard drives detected”, keep the TNAS powered on and insert the HDDs.
8. Follow the instructions on the webpage to reinstall TOS.

Note:
Reinstalling the system normally only resets the system configuration and permissions. It does not delete the data on the hard disks if these disks have been used in this TNAS before.
However, to prevent any unexpected situation, we recommend backing up your data before reinstalling the system if conditions allow.
This method only applies to HDDs that have always been used in this TNAS.
If the HDDs were previously used in another device, or if the installation wizard shows prompts such as:

• Format
• Delete data
• Create Storage Pool
• Create RAID
• Initialize disks

please stop the operation immediately and do not continue.
