i tested on pc-3000 heads and SA surface, and modules- its perfect.
its imposible what theese all are bad sectors. maybe some problem with translator or dameged P-list. i did translator regenertion on P-list but no luck. the Hdd was given to make data backup, when it returned back it has this problem. now Hdd not contains any data. maybe it was connected bad or dropped, but if was dropped all hdd must be read bad not only the 2/3 of it. what the problem can it be?

Did you do something with modules?
You can try to regenerate translator but most likely it's a media damage.

IDNF.
It looks SA issue.

I have no exact idea.
Try to find trash in modules....

Janos

If it was translator issue it would be IDNF right from the start and no readiness timeouts.

This is not always true.

Translator corruption can cause partial unreadable user space.

Additionally, the continous IDNF shows it is SA related.
The IDNF is _between_ the AMNF and the ABRT/UNC in read problem levels.
So, it is impossible to hiting always the middle level....

It is SA.

Janos

i think it is problem with SA too, but when i check modules and SA surface it gives me no error, its like only 2 3 and 4 5 heads reads good but gives error like the translator coruption. its strange - the 0 1 heads read without errors. how to be sure that it is translator? how to check it if it contains the trash and which module is corupted? modules 20 and 25 i cant take from other HDD, the translator is unicue, cause i have other 4 hdd of this model that are working good.
some idea how to solve the problem???
