chkdsk F: /r This will take a long time (hours for large drives), but it will try to map out bad sectors.
chkdsk E: /f It will scan for logical errors and fix them immediately.
Have you ever lost data because you ignored a CHKDSK warning? Let me know in the comments below.
chkdsk D: (Replace D: with your drive letter) Use this to fix errors AND recover bad sectors.
We all know the drill. Your computer starts acting up. Files take forever to open, weird glitches appear, or you get that dreaded "corrupt file" notification. Most troubleshooting guides tell you to run chkdsk C: and call it a day.
But what if your problem isn’t on your main Windows drive? What if you have a secondary internal drive (D:), a massive external backup drive (E:), or a finicky USB stick (F:)?
Here is exactly how to run chkdsk (Check Disk) on any other drive. Running CHKDSK on your C: drive usually requires a reboot because Windows is actively using it. However, secondary drives are often dismounted —meaning you can scan and fix them in real-time without restarting.
