NAS540: Volume down, repairing failed, how to restore data?

BTW is it possible to stop the buzzer from the command line?

Is there an easy way to copy my files from these drives?

Hi I finally got back my data but the recovery process was extremely long and difficult and only works if the actions are taken in the right order:

[before that I have taken all of the above-mentioned steps but I couldn't get it working]

equipment:

• Zyxel 540 NAS with 4 drives inside 2 TB (wd green) each,  drives were grouped into 2 volumes consisting of 2 drives in raid10 (each drive from a volume is mirrored on the other one)
• 4TB usb drive (seagate)

1. firstly I run fsck on each of the drives
2. then I mounted 1st drive from the 1st volume from the raid array
3. I mounted the usb drive and created ext4 partition
4. I rsynced these 2 drives, r sync operation took me 4 days and nights (which is extremely strange and long)
5. I unmounted the 1st drive from the 1st volume 
6. I mounted 1st drive from the 2nd volume from the raid array
7. I rsynced  this drive with the usb drive , and this time r sync operation took 3 days and nights (which is also too long )
8. I unmounted the 1st drive from the 1st volume 
9. I formated the former NAS drives via ssh and reinitialised volumes in the webface
10. I'm currently running rsync to synchronise the data on NAS with those on the usb drive.

This ends my problems. Thank you for your time.
