I got this issue that my E: drive becomes inaccessible. I thought that some corrupted files and bad sectors might exist on the drive. So I tried to run the SFC -sfc / scannow You can use the `chkdsk` command in the Command Prompt to repair corrupted files on a drive and make it work again. To do this, open the Command Prompt as an administrator, type `chkdsk C: /f` (replace `C:` with the drive letter of the problematic drive), and press Enter. This command will scan the drive for errors, fix any problems it finds, and attempt to recover any data that can be salvaged.
If the System File Checker (SFC) is not working on your Windows 10 computer, you can try running the DISM (Deployment Image Servicing and Management) tool to repair corrupted system files. You can access DISM by running the command "DISM /Online /Cleanup-Image /RestoreHealth" in the Command Prompt as an administrator. This command will scan for and repair corrupted system files, and if it finds any issues, it will attempt to restore them from the Windows installation media. If DISM is also not working, you can try running the command "sfc /scannow /offwindir" to scan the system files in offline mode, or try running the command "chkdsk /f" to check and repair any disk errors."
