Getting stuck at scanning and repairing drive is one of the biggest headaches for Windows 10 computer users. It happens when CHKDSK's scanning and repairing hard drive seems to never finish, halting at a certain percentage value and not advancing. Generally, you might see Windows 10 get stuck at scanning and repairing the drive C: or D:. The scan will often partially complete, but then get stuck on a particular percent.

About Scanning and Repairing Drive

Scanning and repairing drive is a disk checking process in Windows Automatic Repair (the same as Startup Repair). When there is a boot issue on the computer, Automatic Repair will start automatically and you will see the computer screen showing Preparing Automatic Repair, Diagnosing your PC, and then Scanning and repairing drive C, D... You may also initiate the Startup Repair by yourself from the Advanced Options in the Windows Recovery Environment (WinRE). If the "Scanning and repairing drive" process gets stuck, it suggests that there is trouble reading the drive, which might result from disk connection issues or disk errors like bad sectors and file system errors.

Fix 4. Disable Automatic Repair

Automatic Repair doesn't always work. It is known to cause troubles like Windows stuck at "Preparing Automatic Repair", Automatic Repair loop, and the one in the discussion, "Scanning and repairing drive" stuck. Therefore, you can disable Automatic Repair to avoid these problems. To get it done, you will need to enter the Windows Recovery Environment or the Windows installation media.

Step 7. To disable Automatic Repair, enter bcdedit /set {current} recoveryenabled no. ("{current}" indicates the current OS and change the value to "no" will abort Automatic Repair.)

Step 8. Restart the computer.

Check Disk

Fix 6. Recover Data

In most of the cases, one of the solutions above will fix the "Scanning and repairing drive C, D..." stuck issue in Windows 10. But there may be exceptions that the C drive (the system drive) is severely damaged and you can't boot into Windows even after you try all the fixes. In such a situation, you will need bootable data recovery software like EaseUS Data Recovery Wizard with Bootable Media to rescue all the files from the non-working PC and then reinstall Windows. 

To create a bootable USB or CD/DVD:

Step 1. Create a bootable disk.

Set to boot the PC from "Removable Devices" (bootable USB disk) or "CD-ROM Drive" (bootable CD/DVD) beyond Hard Drive. Press "F10" to save and exit.

Step 3. Recover files/data from a PC/laptop hard drive that won't boot.

Frequently Asked Questions

1. Why choose EaseUS Data Recovery Wizard?

"EaseUS Data Recovery Wizard is the best we've seen. It's far from perfect, partly because today's advanced disk technology makes data-recovery more difficult than it was with the simpler technology of the past, but it's fast and efficient..."PCMag

"The first thing you'll notice about EaseUS Data Recovery Wizard Pro is that its interface is very clear and uncluttered, with only a small collection of self-explanatory controls. You won't find lots of extra options hidden in a system of hidden menus, either; what you see really is what you get."techradar

"Recover lost files, even after deleting a partition or formatting your drive."Macworld

2. Why cannot I recover 2GB data for free?

It is recommended to check the version installed is Free or Trial because they are different versions.

Trial has data preview function but cannot save any files, while the Free version enables to recover 2 GB files. The default free space is 500 MB and you may share the product on social media to get another 1.5 GB.

3. Why cannot the recovered files be opened?

A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.

If the files with original file names and folder structures cannot be opened, one possible reason is the corrupted directory info. There is still a chance to recover the data content with the RAW Recovery method in our software.

The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.

5. How can I check whether my data is recoverable or not before purchase?
