So it is still stuck on 90%?

yes it was after 18 hours.
No I have switched off unplugged the power cable and it works normally but I don't know for how long

The problem is that I can't do nothing because I have no access now at the NAS (probably because is doing the disks test). The only way to go out from this step I believe is power off the NAS pulling again the power plug

Sorry - I was assuming that you were running the disk test from the web UI - but you were running the boot menu.

I suggest
-downloading the logs again, and taking a look at the SMART statistics
-scheduling an on-line disk test for each volume (which will reduce performance a bit, but will keep your data available).
-disable disk spindown (if it is enabled). The drives will spin down during the on-line disk test (surprising but true), which will slow the test down.

Are you running plex? (I know you said "no apps" - just want to confirm).

Thanks for the answer.
Just an update about the system situation:
I have done a test, it seems that the system works properly if I use the NAS, so I have run a ping/t of the NAS IP address and now the RN104 is working properly.
Regarding your suggestion I have first download the log and attached you can see the SMART history log file
For the second point could you please let me know how to do it?
The disk spindown has been always disable
There is only one app running and is transmission

I have the same issue. Sadly, 6.2.3 has made it worse than before. I'm just going to disable the virus checker to see if that has any effect. The drive locked at shutdown yesterday and then in use today. I'll upload log files.

Tonight watching a movie it stop 3 times. I don't believe is a matter of the disk.
Something happen that lock the drive even if I am using the NAS.
And this started only after the updating to 6.2.3
Is there a way to go back to 6.2.2 just to understabd is the matter is this?

You can install 6.2.2 via the web admin interface.

Go to System > Settings > Update, click the Install Firmware button and browse to where you have downloaded the 6.2.2 firmware to, select it and follow the prompts.

Just an update about the problem.
Yesterday I have disable the virus checker following the test that is doing af8 and last night I didn't have any issue.
The system start at the specific time and power down at midnight at the time scheduled; when it was on I tryed several time to press the power button and it worked normaly.
Also the system had work normaly without any lock show me the data and let me see the movies.
The system is still on 6.2.3
I will countine to check on the next days what happen

Tonight an other lock even if I have disabled the virus checker, so I decided to move back to 6.2.2 and see what happen.
I will keep you informed

So far, with virus checker disabled no lock ups but will keep monitoring.
