  9. Copy the hardware ID and use it to find the correct driver from the official manufacturer website.

Avoid downloading drivers from unknown websites. The safest sources are Windows Update, the PC manufacturer, the motherboard manufacturer, or the hardware manufacturer.

When Should You Update Drivers in Device Manager?

You do not need to update every driver manually just because a newer version exists. Updating drivers is most useful when there is a specific problem or compatibility need.

You should consider updating a driver when:

A device is not working correctly.

Windows shows a yellow exclamation mark.

A device is missing after a Windows update.

You installed new hardware.

A manufacturer recommends a driver update for your model.

A graphics, audio, network, or storage device has a known issue.

You should be careful with driver updates when:

The device is working normally.

A third-party tool claims many drivers are outdated but Windows shows no issue.

The driver comes from an unknown website.

The driver is not designed for your exact device model.

For critical components such as chipset, storage controller, graphics card, and network adapter, downloading drivers from the official manufacturer website is usually safer than using random driver updater tools.

Device Manager vs Windows Update: Which Should You Use?

Device Manager and Windows Update can both help with drivers, but they are not the same.

ToolBest ForNotes
Device ManagerUpdating, rolling back, uninstalling, enabling, disabling, and checking individual devicesBest for troubleshooting a specific hardware problem
Windows UpdateInstalling recommended and optional driver updates from Microsoft and device partnersBest for general system driver maintenance
Manufacturer websiteGetting the latest driver for a specific PC, motherboard, graphics card, printer, or accessoryBest when Windows does not find the correct driver

A good troubleshooting workflow is:

  1. Check the device status in Device Manager.
  2. Try Windows Update or Device Manager update.
  3. If the problem continues, download the driver from the official manufacturer website.
  4. If the new driver causes problems, use Roll Back Driver or uninstall the device.

What to Do If a Drive Becomes Unreadable After a Driver or Hardware Issue

Device Manager can help identify whether a disk drive, USB drive, external hard drive, SD card reader, or storage controller is detected by Windows. However, it cannot recover lost files by itself.

If a drive becomes unreadable, disappears from File Explorer, shows a driver problem, or asks to be formatted, avoid writing new data to the drive. Do not repeatedly format, initialize, or repair the drive before checking whether important files are recoverable.

In this situation, Magic Data Recovery can help scan the affected drive and recover lost files from deletion, formatting, file system errors, partition problems, or inaccessible storage devices when the original data has not been overwritten.

Use Device Manager to check whether Windows can detect the device. Use Magic Data Recovery when the main problem becomes data loss or inaccessible files.

Conclusion

Device Manager is a built-in Windows tool for viewing, managing, and troubleshooting hardware devices and drivers. You can use it to open device properties, update drivers, roll back drivers, uninstall devices, enable or disable hardware, check error codes, and fix common driver problems.

To open Device Manager quickly, right-click Start and choose Device Manager, or press Win + R, type devmgmt.msc, and press Enter. If you see a yellow exclamation mark, an unknown device, or a disabled device, open the device properties first and check the Device status message before changing drivers.

For driver problems, Device Manager is useful for targeted troubleshooting. For general driver updates, Windows Update and official manufacturer websites are usually safer sources. If a storage device becomes unreadable or files are lost after hardware or driver issues, Magic Data Recovery can help scan the device and recover lost data when it has not been overwritten.
