Looks like it's pretty bad. Unfortunately with SATA drives you can't just change its control board, it's more involved than that. You can try one thing that worked for me couple of times. Unscrew (very carefully) it's control board, clean contacts with alcohol and put back.
Other things people tried (me too), if it's overheating and failing because of that, freeze it good in fridge and try while cold, you have 10-20 minutes to unload the stuff from it.
If spindle or heads are sticking, gently tap sides.
A friend of mine had also a peculiar problem when HDD would work properly only when data cable was connected after computer was fully booted, otherwise it was also a "sometime" HDD.
Problem with all those remedies is that it could terminate HDD.
There are services (expensive) that specialize in data retrieval, it depends how important data is.
