Hard Disk Bad Sector Repair4/14/2021
Not only this, physical storage devices like hard drives are the new banks that provide the users with the facility to store their data.Among these, bad hard drive sectors remain the leading cause.As a result, this part of the hard drive cannot be accessed or written upon.
![]() Hence, it is a common scenario to encounter bad sector, even in drives that have been newly manufactured. Interestingly, the data on the rest of the disk will be unaffected and the disk will still be completely usable. Hard Disk Bad Sector Repair Software Such AsOnce the computer system is successful in identifying a sector as unusable, certain software such as Disk Utility software are smart enough to mark the affected sector as unusable. As a result, the Operating System learns not to attempt any data storage in this sector in the future. Therefore, this translates to the fact the storage capacity of the hard drive will come down in proportion to the size of the bad sector space. Bad sectors due to faulty drive head can spread to other sectors on the disk. ![]() Due to the damage being physical in nature, such bad sectors can only be prevented and cannot be repaired. The HDD head may have touched the platter causing damage, or dust settled on the sectors can also ruin it. For SSD drives, their memory cell may have worn out, but for hard drives, there can be multiple reasons for physically bad sectors. When a logical bad sector occurs, the operating system tries to read the data on the hard drive in a particular sector. Also, before ECC (Error Correcting Code) the data in a drive is accessed, a checksum is performed if the checksum does not match, you have a bad sector. They automatically check for bad sectors and reallocate the data on those bad sectors to new ones. In such scenarios, certain SMART tools can be used to access the health of your hard drives as an indicator of bad sectors. In an ideal scenario, this must take place in a transparent manner before the data can be lost. But if the drive has physical damages, multiple parts of the drive are affected generally.
