I. What is parameter error ? What are the reasons for the parameter error of the hard disk?

“Parameter error” is a Windows 10/8/7 bug that hinders device access and data retrieval. It triggers an error message stating “The parameter is incorrect” when attempting to open the disk.
the parameter is incorrect
The causes of such errors are usually the following:
● The device driver is faulty (the hard disk is removed abnormally)
● The file system is damaged
● The power connection failed or the device connection failed
● Sector corruption or disk write error
● virus infection
To ensure data safety, it is highly recommended to use data recovery software to restore and save data from the hard disk experiencing “parameter error”. Afterwards, proceed with repairing the issue. Now let’s explore the process of recovering data from an inaccessible hard drive.

2. Use the SFC command to fix the parameter error problem of the hard disk

It is very simple to repair a damaged hard disk with the help of the SFC command. The specific steps are as follows:
Step 1: Connect the hard disk to the computer, and make sure the hard disk can be recognized.
Step 2: Search (cmd) directly in the search box in the lower left corner, and select (Run as administrator) to open the command prompt tool.
run as administrator
Step 3: Open the command prompt window and enter the command “sfc /scannow“. Press Enter to execute the hard disk recovery command. After the repair is completed, check if the hard disk can be accessed normally.
