How to Fix the Parameter Is Not Correct Error in Windows

Seeing the “Parameter is not correct” error? This mainly occurs when you’re trying to view or access the files on a storage device, like a USB stick or external drive. It’s quite a frustrating issue, as it makes you completely unable to view any of those files.

Let’s see how to solve it.

Fix 1: Try a Different Port

Before you do anything else, it’s worth checking your external storage device in a different USB port (if you have one available). It may be that the port you’re using is damaged somehow, which could be triggering the fault. If you try another port and get the same issue, proceed to test out the fixes below.

Fix 2: Run Check Disk

Using CHKDSK utility may fix this. Here’s how:

Step 1. Launch the “Command Prompt” as an administrator. You’ll find it via “Start” or by searching for “cmd” in the search bar.

Step 2. First type “chkdsk”, then the letter of the drive to scan. Then, type “/f” and “/r”. That’ll give you something like: “chkdsk E: /f /r”.

Step 3. Hit “Enter” and let the utility run. It can take a few minutes while it scans the affected drive.

Fix 3: Try a System File Checker Scan

A System File Checker or SFC scan is another built-in Windows utility to try when you get the “Parameter is not correct” error. It looks for corruption in the system and tries to fix it for you.

Step 1. Access the “Command Prompt” via the Start menu or search bar. Make sure you launch it as an administrator.

Fix 8: Reformat the Drive

This is the last resort fix. If all else fails, it may be that your drive is corrupt or simply incompatible with Windows in its current state. Formatting it should fix the issue, but it’ll also delete everything on the disk.

Step 1. Right-click the Windows icon and select “Disk Management.”
