Which error? Are these files huge? If there is a filesystem error, you should see that if you run
dmesg | tail
on the NAS. (You can open a 2nd telnet session, if desired)
Yes, some files are approx. 30/40Gb big.
root@fvdw-sta-kirkwood:/ # dmesg | tail
[ 101.951309] disk 0, o:1, dev:sda2
[ 101.951318] disk 1, o:1, dev:sdb2

For now I will take the most important files and copy them to the other NAS (some fail).
Will get back to you tomorrow. This will took some time! At least I see files being copied so I am so greatful to both of you!!! THANKS!
