– Expand the “Disk drives” category.
– Right-click on your external hard drive and select “Update driver.”
– Follow the on-screen instructions to update the driver.
4. Corrupted File System: If the file system on your external hard drive is corrupted, Windows 7 may have trouble detecting it. To fix this, you can use the built-in Windows utility called “Check Disk.” Here’s how:
– Press the Windows key + R to open the Run dialog box.
– Type “cmd” and press Ctrl + Shift + Enter to open an elevated Command Prompt.
– Type “chkdsk /f X:” (replace X with the drive letter assigned to your external hard drive) and press Enter.
– Wait for the scan to complete and follow any prompts to fix errors.
