How to Fix Bad Sectors in Hard Drive Partitions and Recover Lost Files
A bad sector is a cluster of storage space of the hard drive that appears to be defective and doesn’t respond to read and write requests. There are two types of bad sectors: physical bad sector and logical bad sector. Physical bad sector means the cluster of storage space is physically damaged and can’t be repaired.
