The hard disk is the backbone of computer system hardware configuration because the Operating System is saved on it. All the applications, files, folders, and other data are kept in their sectors. A challenging drive sector is a part of the hard disk that divides files’ load. The performance of hard disks increases with the presence of sectors. Damage in a sector can cause the infamous blue screen error (BSOD.) It implies a problem with the boot sector or the Master Boot Record (MBR) file. So, you should check and repair the bad sectors routinely, and in the present write-up, we will discuss the crucial causes and solutions to help fix this issue.
Kernel for Windows Data Recovery software is a one-stop solution to fix data loss due to bad sectors in Windows 10 (earlier & later versions also). Try the Demo version for free & view your lost files and folders instantly.
A bad sector is that section or space on a hard disc storage unit that is damaged permanently, so the entire information stored in that section or space is lost. It may occur due to physical or mechanical damage, manufacturing flaws/faults, wearing out, physical shock, sudden power cuts, invasion of dust, etc. These are discussed more in the following parts of this blog.
Types of bad sectors:
Here are two types of bad sectors that corrupt and damage your Windows.
CHKDSK repairs soft bad sectors and marks hard bad sectors so they will not be used again. You get a report or information about the bad sector when you run disk checking. It implies that the bad sector should be the soft bad sector; it should be the bad hard sector, which is a more complex situation.
Some of the leading causes that we believe are responsible for the occurrence of bad sectors on the hard drives are listed below:
Note: You can restore damaged partitions from the table. This option is only available when you have a backup, and the partitions are in a good state. Hence, it is an excellent practice to backup at regular intervals.
Note: Use a reliable Anti-virus tool and invest in some power backup systems to address this issue.
When your Hard disk has bad sector(s), irrespective of its nature, viz; logical or physical, there is a reduction in the disk capacity and loss of data on a bad sector. When the disk has a physically bad sector and/or multiple logically bad sectors, then the repair of bad sectors becomes impossible. So, an intelligent decision should be to backup all your data on the hard disk and save it. For this purpose, you can transfer files from the old hard drive to the new hard drive. Suppose you lose any data accidentally or by any mistake. You can use any Windows data recovery software to get all the data on the hard drive and save it anywhere you want. Let us see different methods to repair bad sectors on a hard disk.
Repairing the bad sectors using the built-in tools might be the most effective way to deal with bad sectors on hard drives. It refers to the error-checking utility of Microsoft Windows.
Method 1: To fix bad sectors on Windows 10/8:
To fix bad sectors On Windows 7:
When only a few soft bad sectors are on your drive, try to run the CHKDSK command and format your hard drive. It will help you to repair bad sectors. To do so, follow the steps given below:
Option A: Running the CHKDSK command
Option B: Formatting hard drive to make it reusable
Your hard drive is ready to be reused fresh.
There are no standard solutions to repair hard bad sectors. All you can do is do a low-level format on the drive, resetting the hard drive’s blocks, clusters, and sectors.
A low-level format, also called a physical format, is done at the factory. Thus, you can either take the manufacturer’s help or a repair center.
There is a possibility of data loss after repairing the bad sectors on your hard drive in Windows. Therefore, you need a professional data recovery tool in such cases. One such tool is Kernel for Windows Data Recovery Software. This tool can quickly recover data from any storage media, such as external hard drives, USB drives, and SD cards. Another essential feature is that it can even recover deleted files alongside lost and corrupt data files.
At first glance (see the snippet below), the user interface looks clean and descriptive. The tools prompt the user to choose from the three scan modes. The first mode is a Quick Scan mode; this mode should be selected if you have recently deleted the files as it coarsely scans them. The next mode is Deep Scan mode, and it should be used explicitly in the event of hard disk format and partition deletion. If you have tried both of the previous modes and had no luck, try the File Trace mode. It is the most advanced scan mode, as it scans the drive sector-by-sector.
Bad sectors can occur on the drives for several reasons, briefly discussed in this article. Along with the causes, two methods to counter bad sectors are also discussed. More importantly, there is a chance that you might lose your data. In such dire circumstances, one can rely only on a professional data recovery tool such as Kernel for Windows Data Recovery tool, which can efficiently recover your data files. We highly recommend this tool and ask the user to give it a try.
