Jiri brought to my attention that
that asus provide firmware upgrade which solved his problem.
I found at
utilities which correspond my HDD, i.e.:
1. firmware upgrade utility
2. virtual cd removal utility
I succeeded to run them under windows (wine didn't helped...).
And ... it worked!
After the firmware upgrade the block device was generated, though the
partition was not recognized.
I used the second utility and removed the virtual cd
and everything is getting mounted in linux!
