What are the causes of this problem?

Hard drives are fragile pieces of equipment. It cannot take much impact or stand in high temperatures without getting damaged. When the disk inside the drive touches the head due to shock, it can lead to problems. Power outages that occur during data writing can also be a cause. Bad sectors caused by physical damage are called hard bad sectors, and they cannot be repaired.

Another cause of bad sector is the parity bits that got corrupted by malware, resulting in the data not matching when the hard drive is trying to read them. This is called a soft bad sector and fortunately, it can be repaired.

Part 2: Overview of Hard Drive Bad Sectors

1. What is a Bad Sector?

Before we address the issue of '˜Hard Disk Bad Sector', it is important for us to understand what constitutes the bad sector or what it means. A bad sector on a hard drive is simply a minor sector including the storage space, and if it happens to be defective, it won't respond to read or write requests, which can cause serious loss to your data.

Bad sectors aren't restricted to magnetic hard drives, but also include modern solid-state drives. Bad sectors mainly result from two factors, one, from physical damage that cannot be undone, and the other from software errors, which can be repaired using troubleshooting techniques.

2. Understanding the different type of Bad Sectors:

If you are facing the issue of the 'Hard Disk bad sector', it can be a frustrating affair as finding solutions can be difficult or improbable. Therefore, we begin by understanding what the types of bad sectors are, and how they impact your hard disk.

  • Physical or Hard- Bad Sector: This is the cluster that has been damaged physically. The hard drive's head may have touched the part of a hard drive and damaged it completely. It is also possible that some dust might have settled on the sector, and caused the damage. In the case of a solid-state drive, its flash memory cell may have been getting old, or there would have been the presence of wear and tear, thus causing the entire sector to become physically damaged. This is the type of bad sector that has no hope to be repaired.
  • Logical- or Soft- Bad Sector: This is one of the bad sectors that are not physically damaged, and yet, doesn't work properly. The Windows may have attempted to read the data on the hard disk from this sector and that could have resulted in an error-correcting code (ECC), as it didn't match the contents of the sector, thus suggesting some error. The error can be repaired by overwriting the drive with zeros or through a low-level format. One can also solve the error of the 'hard disk bad sector' by using the Window Desk Check Tool to repair these sectors.

3. Causes of Bad Sectors

We understand the causes behind different types of errors in the '˜hard disk bad sector'.

Physical Bad Sector:

  • The shipping may have been faulty with the bad sectors. The manufacturing and production techniques employed today aren't flaw-free, and there is room for error. Therefore, solid-state drives tend to ship with a few defective blocks. Marked as defective, they are remapped to some of the solid-state drive's extra memory cells.
  • Natural wear can also result in physical damage as discussed above as they are re-written quite many times. They'll be remapped to the solid-state drive's extra or '˜overprovisioned' memory, and when the solid-state drive runs out of memory, the capacity of the driver shall begin to drop.
  • Traditional magnetic hard drives can see bad sectors due to manufacturing error, natural wear, dropping, and poor handling, which results in the hard drive's head to touch the platter and does damage some of the sectors. Air entering through the otherwise sealed area or the setting of dust are contributing factors in the damage.

Soft Bad-Sectors:

  • They are caused by software issues, like sudden shutting down of the PC, or the hard drive being disconnected in the middle of the writing to the sector.
  • Mismatch in the error-correction code is also one of the reasons for this error.
  • Viruses and Malware.
