How to Repair a Corrupted Hard Disk Without Formatting – Usually, when something goes wrong with your Hard Drive, the go-to solution is to format it. This formatting causes the hard drive to erase everything on the hard drive. You lose every data and information stored on the hard drive.

This article explains how to repair a corrupted Hard Disk without formatting. In other words, steps to repair a corrupt hard disk without losing the data.

Note: An error prompt may come up on your screen asking if you want to format the corrupt drive when you run the hard drive. Do not confirm the prompt. Instead, click on cancel and exist immediately to avoid permanent loss of data.

Causes Of Hard Drive Corruption

When a drive is formatted with a file system such as NTFS, FAT16/32, exFAT, etc., it generates a table where file records are conserved. NTFS develops a Master File Table (MFT) while FAT file systems reserve these records in the File Allocation Table (FAT). After format, every file you cut/copy/paste enters a record in the table.

These file records include the physical address of the file on the hard drive along with other file details such as file format, creation date, modification date, size, etc.

So when a drive is connected to the system, the OS reads the file system’s table and expresses the contained files and folders along with the details retrieved from the table. When this table is wrecked, the OS can’t interpret the file system and thus, express the drive as RAW.

It’s quite possible that the above steps fail to repair the corrupt hard drive. Sometimes, the corruption is severe, and the methods mentioned above can only fix a few minor drive corruption issues.

Nonetheless, a data recovery software like the Remo Hard drive Recovery tool Standard can promptly restore files from harshly corrupt and formatted hard drives or deleted partitions. While Windows may not comprehend a corrupt hard drive as functional, this software natively supports recovery from a corrupt (RAW) hard drive.

4. Using CMD (Command Prompt)

This is another type of scan you can run called CHKDSK scan to repair the corrupted hard drive without formatting.

CHKDSK command prompt inspects the file system and file system metadata of a volume for plausible and physical errors. If used without parameters, CHKDSK displays only the volume’s status and does not fix any errors. If used with the /f, /r, /x, or /b parameters, it fixes errors on the volume.

  • The “/f” parameter tells CHKDSK to fix any errors it discovers.
  • The “/r” tells it to find the bad sectors on the drive and recover coherent information.
  • And the “/x” forces the drive to dismount before the process commences.

Follow the procedure below:

  • Next to the Windows Start menu, in the “Search Windows” box, type cmd.
  • On the search result, right-click on the “Command Prompt” and select “Run as administrator”.
