There might be chances that your hard drive consists of bad sectors. When a good hard disk comes up with one or more bad sectors, the disk goes bad; and, when such a situation occurs, the data stored in the bad sectors may get lost. There are scenarios when the cause of bad sectors could be a faulty drive head. In such cases, there is a likelihood of spreading the issue to several other sectors of the disk. Hence, in situations where the hard drive experiences one or more bad sectors, it is highly advisable to back up the disk data or fix the bad sectors instantly.
Further, I suggest you to check the below link that explains all the measures to check the health of any hard disk:
