CHKDSK stuck at 11 percent in Windows 10

“My computer is getting slower and slower recently so I decided to check system for errors on Windows 10. I input CHKDSK C: /f in CMD, hit Enter, and it starts normally at the very first. I let it run and had supper after that. Two hours later when I came back, it stuck at 11 percent and no further advancing. It is saying: Scanning and repairing drive (C:): 11% complete. Generally speaking, it shouldn’t take that much time. Anyway, I left it alone for one more hour, and nothing proceeds. Help please.”

Why do you get CHKDSK Windows 10 stuck?

CHKDSK helps ensure the computer’s files and file system are in order. It also checks the physical disk to see if there are bad sectors, and it will try recovering those data if you input /r with CHKDSK.

CHKDSK Windows 10 stuck event can be explained from the following two aspects. On the one hand, there are bad sectors or corrupted files on your relatively old hard drive. If you run CHKDSK /r and get stuck on Windows 10, probably there are plenty of data need to be recovered and lots of bad sectors needing repair. Therefore, it is normal that several hours even a day is required. Let it run overnight if you feel it is repairing something.

On the other hand, it could be a problem with Check Disk utility. When you run CHKDSK in Windows environment, the disk-checking process may be affected by running software or damaged system files. Therefore, it is worth running CHKDSK without booting Windows if you have Recovery USB around or clean-booting your Windows 10 by disabling all Services in System Configuration.

Replace slow hard drive with new one

A hard drive serves five years or more is not suggested to run CHKDSK /f or CHKDSK /r, since those commands are telling Windows to find bad sectors and recover data that is recoverable. No wonder it requires hours to complete. In addition, a disk is periodically checked for file system errors, bad sectors, lost clusters, etc. during Automatic Maintenance, which makes CHKDSK not that necessary.
