If you encounter this error (see snippet below), then it means that there is something wrong with your hard disk drives. This happens when you try to boot your Windows. As pointed out by the Windows user, this error might cause boot-loop issues. More importantly, you might be worried about the data that is stored on your drives. It might be the case that there is a problem with the boot sector or the Master Boot Record (MBR) file. However, this is not the case with every user. We have found some common causes for the disk read error.
MBR is a boot sector that holds information about the partitions and acts as a loader for the OS on your machine. It is created when you first install Windows on the first partition you created. It is the First 512 bytes on your hard disk. If MBR is damaged, then you won’t be able to boot into Windows.
Precaution: One should always back up the MBR. This can be done by a single line command in the Command prompt-
dd if=/dev/sda of=/path-to-save/mbr-backup bs=512 count=1
Here path-to-save is the path where you have saved your mbr-backup.
This can make MBR corrupt. An MBR virus is a memory-resident virus. It can very easily copy itself to the fest sector of the drive containing the partition table. To make things worse, another type of virus that infects the boot sector of an HDD or FDD is Boot Sector Virus.
Data corruption of partition tables can be due to virus attacks, power outages, and faulty disk operation.
Precaution: Use a reliable Anti-virus tool and invest in some power backup systems.
Invalid partition tables can cause partition loss and boot issues. If the partition tables get damaged, then the system will not be able to locate the partitions containing the booting data files.
Precaution: If your partition tables have become damaged, then it might be wise to restore them from the backup. If you had a backup when it was in a good state, then the problem can be solved quickly. Hence it is an excellent practice to make a backup.
Any Physical dame to the drive can prohibit the user from accessing the contents or booting from the drive.
Try the following manual methods to fix the disk read error:
You cannot run CHKDSK from the command prompt. Hence, try booting from the Advanced Options menu, and click on Command Prompt.
After opening the command prompt enter the following command:
chkdsk X: /f /x /r
Note: In the above command X:/ is the root drive.
If any issues are found, then it will be fixed, and you will get a report of errors. If not, then you will see the following message:
“Windows has scanned the file system and found no problems.”
For this task, you will need the original Windows 10 installation disc to repair the MBR
If the bootrec utility doesn’t solve your problem, then one can try the EFI bootloader as outlined below:
sel disk 0
sel vol 1
If the volume number is different than 1, then replace 1 with that number.
DiskPart successfully assigned the drive letter or mount point.
cd /d x:\EFI\Microsoft\Boot\
ren BCD BCD.backup
bcdboot c:\Windows /l en-us /s x: /f ALL
Resetting your BIOS could help restore your system’s default settings. To reset follow the steps below:
It is essential to check the hard drive’s SATA and power cables in case of disk read errors. Look for any loose connections or a faulty connection using a multimeter. Replace the old cables with the new ones.
It is often the case that after recovery, you might lose your data. Therefore, you need a professional data recovery tool such as Kernel for Windows Data Recovery. We highly recommend Kernel for Windows Data Recovery. It can recover data from almost all types of storage media like an external hard disk, USB drives, SD cards, and more. One of the most important features is that it not only recovers the corrupt and lost data it can also recover the deleted files.
The welcome screen (see the snippet below) prompts the user to select from the three modes. The first one is a Quick Scan mode; use this one if you have recently deleted your files as this mode coarsely scans for the data. Choose the second mode that is Deep Scan mode in the event of Hard disk format and partition deletion. If you have tried both modes with no avail, then try the File Trace mode. This is the most advanced scan mode as it scans the drive sector-by-sector.
Disk read errors are quite common and can happen due to various reasons, which are discussed in detail in this article. A few remedies are also discussed to counter this issue. Furthermore, there is a chance that in the process, you might lose your precious data. Hence in that scenario one can rely on Kernel for Windows Data recovery tool which can efficiently recover your data files. We believe that user will give this tool a try.
