It turned out that hdd from the previous post
http://forum.hddguru.com/seagate-serial-number-change-5400-t22908.htmlhad damaged head.
The heads have been changed and we started to clone it.
We started from LBA 200 mln becouse we noticed a lo of slow/damaged sectors in LBA 0-200mln.
When we finished lba 200-end , we started lba 0-1mln.
It turned out it was heavily damaged (2% bads).
Then we wanted to clone lba 150-200mln. The disc started to get BUSY (becouse of UNCR ?) more frequently and cloning has been impossible.
So we returned do the beginning and cloned lba 1-2mln. It get BUSsier every minute.
The we scanned it with MHDD (2xF4) looking for udamaged area in 2-200mln. So we jumped (arrow up , arrow down) through it.
We found that 150-175mln looks promising. So we started to clone.
In DMDE the area turned out to be unreadable. We started to scan 150-175 again in MHDD and now it was unreadable (UNC, 'x' and '!' in MHDD).
We checked the area we cloned first (200-end) and
to our surprise it was unreadable too.
We thought that head/heads were dead although lba 0-1mln looked the same (readable, with some bads).
We put the heads to hd it came from (donor) and it worked like a charm.
So we put them back into our hd.
In terminal in T>V4 it shows that bads are distribiuted equally on the heads.
Question: What should we do get access and copy these lba 2-200 ?
