Physical DamageˇG

If the replacement results still in vain, it shows HAD is in bad condition and it needs further assistance from the professional data recovery company.
Logical DamageˇG
It is available to use SPFDisk tool to deal with partition destroy problem. But it should be limited in the term that only one partition exists in the HDD.(Users are not recommended to handle the HDD over two partitions due to the complication it occurs).
Although other tool like Final Data can also handle the logical damage problems like mis-format, mis-delete file, mis-GhostˇK, but users have to store data to another HDD firstly. Keep the original status of HDD to avoid overwritten for further data recovery repeatedly.
