Recover Corrupted Hard Drive without Formatting on Your Own

Hard drive corruption is a common issue that can occur at any time due to various reasons. When a hard drive becomes corrupted, all the data stored on it becomes inaccessible. Fortunately, you can recover corrupted hard drive in most cases. There are several methods available to do so.

Reasons That May Cause Hard Drive Corruption

There could be a number of reasons behind hard drive corruption. Following are some common causes:

  • File System Errors: Hard drive can get corrupted due to a file system error. When such an error occurs, hard drive becomes RAW and the only way to make it work again is to format it.

  • Bad Sectors: If there are any bad sectors on a hard drive, they can cause the drive to become corrupted. Recovering data from such a drive is very difficult.

  • System Crash or Physical Damage: System crash or physical damage can also corrupt a hard drive.

2How to Fix Corrupted Hard Drive on Your Own?

Step 1. Run CHKDSK Scan

CHKDSK is a built-in Windows tool that scans the storage devices, marks the bad sectors, and fixes various file system errors, hence preventing data corruption. You can run CHKDSK scan in order to fix the corrupted hard drive.

Step 1. Launch Command Prompt on your Windows PC via Start Menu.

Step 2. If your corrupted hard drive does not have a letter, then assign one via the Disk Management tool.

Step 3. Next, on CMD window, input "chkdsk /r /f X:" (X here is the letter of the corrupted drive) and press 'Enter'. Windows will start scanning the drive for errors.


If any warning message appears during the process, press 'Y' and then press 'Enter' to continue the process.


Step 4. Once the process is complete, restart your computer. Then see if the drive is accessible.

Step 2. Run SFC Scan

After performing the CHKDSK scan, you should run SFC scan in order to fix the missing or damaged Windows system files that may cause hard drive corruption. SFC scan checks system file integrity and replaces damaged/corrupted systems files with a cached copy to fix the problem.

Follow these instructions to run SFC scan:

  • 1. Launch Command Prompt on your Windows PC via Start Menu.

  • 2. In the CMD window, type sfc/scannow and press Enter.

  • 3. If the hard drive you want to scan is an external drive, then input this command: sfc /SCANNOW /OFFBOOTDIR=x:\ /OFFWINDIR=x:\windows (x here is the letter assigned to the external drive that you want to scan)

  • 4. Now, wait for the scanning process to complete. Once it is complete, restart your computer. Then, see if the drive is accessible.


Symptoms of Hard Drive Corruption

Just as there are a number of reasons that can cause hard drive corruption, there are several symptoms of hard drive corruption as well. The symptoms of both internal and external hard drive corruption are generally the same.

Here are some common symptoms of hard drive corruption:

  • External hard drive is not recognized, does not show up in the system, or not being read while plugging into computer.

  • Drive is not accessible or one of its files/directories gives an unreadable error message.

  • When accessing the drive, you get a notification that you need to format it in order to access it.

  • Hard drive becomes RAW or shows 0 bytes of the total size.


There could be a number of reasons behind hard drive corruption. Although there are several ways to fix/repair a corrupted hard drive, the most important thing is to recover your valuable data from it before proceeding. For this purpose, it is recommended that you use iMyFone AnyRecover as this tool specializes in quickly recovering all types of lost/inaccessible files from corrupted hard drives.
