Solution 2. How to Repair Corrupted Hard Disk Using CMD

When a hard drive's file system gets corrupt and you can't access the hard disk, you can run a CHKDSK scan to repair the corrupt hard drive without formatting it.

The CHKDSK command checks the file system and the file system metadata of a volume for logical and physical errors. If used without parameters, CHKDSK displays only the volume's status and does not fix any errors. When used with the /f, /r, /x, or /b parameters, it fixes errors on the volume.

Step 5. EaseUS Todo Backup allows users to save the backup files to every device that is handy for you, like a local hard drive, external USB drive, SD card, network drive, or a NAS drive, plus a cloud drive of the EaseUS brand. We personally recommend users to choose the cloud drive prior to a pysical drive to save important backups due to the greater accessibility, flexibility and safety.

To be able to access to EaseUS cloud, all you need is an email registration and login.
