What is ScanDisk? Can you run the ScanDisk command to scan and repair drive issues in Windows 10? If you want to apply ScanDisk on newer Windows versions after MS-DOS (like Windows NT, Windows 9x, and Windows 3.x), you should turn to its successor CHKDSK, which you can find in [1] Windows Properties, [2] Command Prompt, and [3] EaseUS Partition Master - a third-party partition manager for earlier and newer Windows operating system.

What's ScanDisk?

Also known as Scan Disk, ScanDisk is a DOS-based Windows utility for automatically detecting and correcting hard drive issues and file system errors. It was first introduced in MS-DOS 6.2, so ScanDisk has had a long history now. Despite that ScanDisk can improve the performance of your hard drive and help maintain the Windows file system, it is too old to retain in the later Windows operating systems, which has been fully replaced by the upgraded utility called CHKDSK (pronounced Check Disk).

That is to say, according to different Windows operating systems, you got different ways to evoke the tool to perform its duty.

ScanDisk is available and executable in:

  • Windows 95 and 98
  • Windows 3.x and MS-DOS

*Windows NT is another senior operating system but it's not shipped with ScanDisk. Most often you can use various third-party utilities to check disk integrity for Windows NT.

In later Windows OS - Windows XP, Vista, 7, 8, 8.1, 10, ScanDisk is replaced by CHKDSK.

Learn more about ScanDisk:

  1. 1. ScanDisk checks exclusively the FAT-formatted hard disks, like FAT12, FAT16, and FAT32.
  2. 2. ScanDisk can recognize compressed volumes and long filenames.
  3. 3. ScanDisk can automatically repair cross-linked files and lost clusters.
  4. 4. You must boot the computer to Safe Mode to run ScanDisk.
  5. 5. Windows 95 OSR2 and Windows 98 run ScanDisk automatically if the computer is shut down improperly.

What's CHKDSK?

Being the successor of ScanDisk in newer Windows operating systems after Windows XP, CHKDSK is developed to monitor your disk drive's health. It starts scanning the file system on the disk drive and analyzing the integrity of the files, file system, and file metadata on the drive. It repairs issues if there were found any.

Using CHKDSK to check, scan and repair hard drive errors is becoming much easier due to the intuitive user interface in the program. There are two ways for Windows users to access the CHKDSK utility, including Windows Properties and Windows Command Prompt. 

How to Run ScanDisk in Windows 10/8/7

Method 1. Run CHKDSK in Windows Properties

Step 1. Open Windows File Explorer (Windows + E keys) > right-click on the drive you want to check and repair > select Properties.

Step 2. In the Properties window, switch to the Tools tab. Under the Error checking section, click Check
