I have a question about SA errors that are in UBA , most of the cases in Maxtor Athena drives when u load loader and check SA surface it gives error in UBA 391 to 400 that which corresponds to the G-list module after rewriting that module still same error and also no problems while writing .

My question is that should i write Data copy1.smb the structure module for the UBA or is there any other way for repair UBA errors .

Thanks ..

Yes, quite often it helps.
You should save all good modules, rewrite Data copy1.smb and write saved modules back right away.

Thanks for the idea i will try .
