It’s a rarity that when a good hard disk comes up with one or more sectors, the disk goes bad; and, when such a situation occurs, often the data stored in the bad sectors may get lost, but the remaining data on the disk will remain unaffected. Above all, the disk is still in the functional state.

Indeed, we can mark them as unusable so that the Operating System will not attempt to store data over them. But, the major downside of this is a dip in the total disk capacity as this reduces the storage space amount.

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. Therefore, in situations where the hard drive experiences one or more bad sectors, it is highly advisable to backup the disk and try to repair  bad sectors in the hard drive instantly.

Here, we guide you on how you can fix bad sectors in hard drive and recover data from it. However, before we look into it, let’s have a quick overview of the Bad Sectors, their symptoms and causes.
