Add defects in writing scan in wd 2tb shrek lt

[roozbeh]

HI MY STAFF AND FRIENDS
data is not important
repairing wd 2 tb shrek lt is important
i solved normal or read issue by physical test and add defects of each head to interactive head and zone and read or normal defect is solved
but my question is about defects in write in writing scan when defects appear all sector in write test went to red and i can not find defects because of many red sectors in logical write scan
test of heads said all 8 heads is in good condition because hdd in normal scan is ok and in in head test all of heads in write is ok
is there any idea

are you sure you did the head tests in read AND write mode? Have you tried writing to one of the selftest modules and refreshing to see if it actually is writing?

hi my friend
shrek lt 2tb has 8 heads
in test heads with pc3000 in write and read all heads is in good condition
i have test write someting in none critical module with copy 0 and 1 and id
it writes and after write i refreshed moudle and it writes
there are alot of defects in some zones
my problem is in write scan when bad sector or defect appear all sector after that goes to red although thet are ok
because of that i could not find defect sectors and check them in interactive head and zone option an cut them from zones
