Sorry, can't decode that. Can you post the exact command which you enter, and the exact output?
chmod +x ./build.sh /dev/sdb1 11:10:41:32:AB:18
cannot access (device) no such file or directory
cannot access (mac address) no such file or directory
Ah, I see.
In this case it should actually be 2 commands. The first one set the scripts executable, the 2nd executes it:
chmod +x ./build.sh
./build.sh /dev/sdb 11:10:41:32:AB:18
Notice that I changed /dev/sdb1 in /dev/sdb. The first one is the first partition on that disk, the second one is the disk itself.
root@mx1:~# chmod +x /home/demo/Desktop/MedionNAS/build.sh
root@mx1:~# /home/demo/Desktop/MedionNAS/build.sh /dev/sdb 11:10:41:32:AB:18
bash: /home/demo/Desktop/MedionNAS/build.sh: /bin/sh^M: bad interpreter: No such file or directory
root@mx1:~#
root@mx1:/home/demo/Desktop/MedionNAS# chmod +x ./build.sh

chmod: cannot access '00:11:41:32:BE:18': No such file or directory

Did you edit and/or open build.sh in notepad, or something like that? This is a typical error you get when running a shell script with Windows line endings.
open yes, edit no

Well, then it's ready. Your NAS should be able to boot from this disk.
okay cool 
the lights are on well?
but I don't see the Nas in between.
what is the IP address?
I don't know. Probably none. The software on disk is only intended to restore the stock firmware on the NAS, nothing more. If you want an IP address, remove the disk, and let the stock firmware boot.
that's the problem.
the default firmware is gone / corrupt
The stock firmware is in that huge mtd*.backup files you downloaded together with build.sh, and the software on the disk restored it in flash.
go try again tomorrow
did you manage to restore you nas with that rescue disk? i tried more than once, but it always failed after booting into u-boot and trying to read specified sectors from ide then... (of course tried with different discs and creating rescue disk on different machines). :-/
