How to Fix “CHKDSK Cannot Open Volume for Direct Access” Error

Hi everyone,

When I try to run CHKDSK on my Windows PC, I get the error message:
“Cannot open volume for direct access.”

Because of this, I can’t scan or repair the drive properly. I suspect another program or service might be locking the disk, but I’m not sure how to identify or fix it.

Can someone explain why this CHKDSK error occurs and share effective methods (around 4 or more) to fix it safely? I’m looking for step-by-step guidance that won’t risk data loss or damage to the drive.

Thanks in advance for your help!
