User Query: How do I fix a cyclic redundancy check error on my external hard drive?
Solution: Have you ever encountered a cyclic redundancy check (CRC) error on your external hard drive, USB drive, SD card, or even your HDD/SSD in Windows? This type of error can cause your files to become inaccessible, and it can be frustrating to figure out how to fix the problem. Luckily, there are several methods you can try to recover your data and get your storage device working again.
In this article, we'll explore some of the common causes of CRC errors on different types of storage devices and discuss the different methods you can use to troubleshoot and fix the CRC error.
Cyclic Redundancy check, well known as CRC, is an error detection code that gives data error cyclic redundancy check if it identifies any changes to the data that is being stored, accessed, or transferred onto a storage device like CD/DVD, SD card, or a hard drive.
In further detail, when CRC is set up on a device, it forms a codeword for data that is to be stored or sent to another storage media. The code word consists of check values that are calculated block-wise before the storage of data.
While the data is being accessed by a computer, the codeword or the check values are compared with the current values of accessed data, and any mismatch in the values results in data errors. This would mean inaccessible data due to hard drive or SD card corruption.
We have divided this article into three parts. In the first part, we will discuss the various error messages that you might encounter while experiencing a CRC (Cyclic Redundancy Check) data error.
In the second part, we will focus on the causes of CRC errors, explaining what can lead to this type of data error in storage devices.
In the third and most important part of the article, we will provide you with solutions to fix your storage device that has encountered a CRC error, so that you can retrieve your data with our help.
As shown in the image above, an error message shows up when you try to open a file or folder on an SD card or hard drive. Usually, the data becomes inaccessible due to logical data error (corruption) or physical damage.
In the following sections, we will broadly discuss the below errors and solutions to solve data error CRC:
While it’s common for the CRC error to occur on external hard drives and portable media like SD cards or flash drives, it can also happen to internal drives and their partitions; in cases like these, you will find the drive to be unallocated or not initialized in Disk management.
Even though you try to initialize the disk from Disk Management, an error “Cannot initialize disk” comes up. The immediate course of action is to understand the causes in order to fix the data error cyclic redundancy check.
As soon as you encounter a CRC error, it becomes very beneficial to learn what causes these errors. Some of the major causes of CRC errors include:
The above-listed reasons cause logical errors except for bad sectors. Bad sectors on the hard drive are formed due to physical damage or wear and tear during read/write operations on the storage device like SSD or flash drive.
There are various methods to fix the Cyclic Redundancy Error on External HDD. Here are a couple of handy techniques for resolving CRC errors:
The computer has a built-in program to find and fix system errors. Even this tool helps in eliminating bad sectors from further usage. Let’s see how to use Disk Utility to solve the CRC error-
The suffix “/f” is used to fix drive errors. The scan takes a while and fixes any logical errors, as shown below
SFC or system file checker is a tool that scans all protected system files of the operating system, including registry files, and replaces them with a copy from a cached folder. However, this method can cause data loss if the data error is caused due to bad sectors or a virus
Using the steps below SFC scan can solve CRC errors due to registry corruptions as well:

If previous troubleshooting methods failed to fix the RAW state or CRC error on your device, you can try formatting the drive. We don't recommend formatting a hard drive without backup, as formatting will erase all your important data.
In case you do not have any options left and you must have to format the drive to fix the CRC error then you can recover data from the formatted hard drive later with Remo Recover.
Step 1: Open Windows Explorer by pressing the "Windows key + E" on your keyboard.
Step 2: Locate the problematic device displaying the CRC error, right-click on it, and choose the "Format" option.
Step 3: Select an appropriate file system for your device, such as NTFS or FAT32.
Step 4: Enable the "Quick Format" option and click on the "Start" button to initiate the formatting process.
By following these steps, you will format the device and create a new file system, which should resolve the CRC error issue.
