HDD vs SSD:: The battle of virtual storage devices

What causes CRC errors?

CRC or Cyclic Redundancy Check error appears when your computer tries to read data from a corrupted hard drive. It could be a local drive, network drive or a CD/DVD. If the drive’s got bad sectors on it, you’re most likely going to see this error. 

Other causes include corrupt files, incorrect drive configuration or faulty app installations. 

How to fix CRC errors?

Here are a few solutions you can try out to solve this problem.

Restart your PC

The first thing you should do in such situations is to try and restart your PC. Restarting your PC can fix a bunch of seemingly random issues that occur without any explanation whatsoever. 

Run the Check Disk utility

The error can very well be a sign of your boot drive failing to perform as it should. Try running the check disk utility to check whether or not your storage drives are, in fact, functional. 

You can refer to our detailed guide here on how to run the check disk utility.

Remove all new hardware

You should first turn your computer off and remove any new hardware or peripherals you may have added to your machine. Then, check to see if your PC boots fine or not. 

If you’re removing multiple devices, remove them one at a time while rebooting your PC every time to isolate the faulty hardware. 

Remove all new software

Like incompatible hardware can trigger this error, so can incorrect software. If you’ve installed any new programs recently, try removing them to see if that solves your problem.

Once again, if you’re removing multiple programs, remove them one at a time and reboot your PC each time to isolate the software at fault. 

Redownload the file

If you’re getting a CRC error while trying to access a file you’ve downloaded from the internet or a local network, try downloading the file again. There’s a good chance that the file may not be fully downloaded and hence, corrupt.

Run the Windows hardware troubleshooter

Windows 10 comes with a few handy troubleshooters that can resolve a bunch of issues. However, for some reason, Microsoft has removed the hardware troubleshooter from the troubleshooter’s menu. So here’s an alternative way to run the hardware troubleshooter. 

 Step 1: Press Windows key + R to open the Run prompt. Type cmd and hit enter.

Repair your system

If nothing else works, the best way to get rid of the error is by simply reinstalling or repairing your OS. 

The Windows Media Creation tool is a great way to install Windows and repair the OS. Using this, you can perform a clean installation or repair your OS without affecting your data.
