Thanks greter, I solved the problem.gretor wrote: ↑22 Jan 2022, 18:15 Hello Ottavio,
For my F2-221 the reinstallation works as follows :
1. switch off Terra Master
2. remove the hard drives.
3. switch on Terra Master.
4. after 2 minutes in switched on state insert hard disks.
5. now the Terra Master is in "initialization mode".
6. run the normal new installation, e.g. with TNAS Desktop App, just as you started your Terra Master the first time.
With kind regards

I managed to reinstall everything, I just feared that it would delete everything, the messages during installation are not clear at least those in Italian (indicates that it will delete all data on the HD, but luckily it does not)
