Hi,
thangssd your question is bit confusing, if your hard drive clicking but detecting why you didnt take backup ? now if drive is detecting but not showing data check first hard drive health with HDDscan or Sentinel software if drive is healthy then use any Data Recovery software scan drive you get data if its logical issue never save data in same Drive after recovery you must save data in another hard drive Good Luck...

it is clicking noise some time detect hard drive when power supply is damage 12v it detect but view data nomal, and now status my hard drive long detect and no view data as emty data on my hard disk, i think it error SA, you can tell me how access SA, thanks

From your description, it appears that one of the heads (not the system one) was most likely damaged ...
If you saw the data (correct disk capacity) then the translator (and SA) was working.
And the clicking appeared when you tried to read from a damaged head (or a damaged preamp channel)
