- Hit the ‘Enter’ button and wait until ‘chkdsk’ utility repairs the disk errors.

After CHKDSK completes error checking, re-connect storage media to the system and then try to access it from File Explorer. If you are able to access the data without any error; immediately copy data from it to a safe location on your system and format the hard drive or any other storage media via Disk Management tool or DiskPart.
NOTE: If the problem persists, you need to format your storage drive. The format will erase all the data from the storage device. If you don’t want to lose data, you must follow the last solution given in this post, which is more effective and optimal.
2. Run SFC Scan
SFC stands for System File Checker, which is used to repair Windows system files including Windows DLL files, registry files, or other protected files. Sometimes due to corrupt file system or registry files, as discussed above, CRC error occurs.
The SFC scan finds the file issue and replaces the corrupt or damaged file with a new one. The entire process can take around 5 to 20 minutes depending upon the files size and volume. To run SFC scan, follow these steps:
- Connect the storage drive
- Click the Windows icon to open the search bar
- Type cmd. Right-click on ‘Command Prompt’ and select ‘Run as Administrator’ from the options
- Type sfc /scannow in the cmd window and hit the ‘Enter’ button to run the SFC scan
