There might be nothing wrong with your SDHC card or the files stored on it. It’s possible that you can’t access your files simply because your memory card reader isn’t working correctly. To eliminate this possibility, we highly recommend you try a different memory card reader, preferably on a different computer.
Nothing wrong with your memory card reader? Then what about its driver? Hardware manufacturers sometimes release buggy drivers that may cause all kinds of issues, and the simplest solution to this problem is to reinstall the driver in questions. On Windows, you can do this from the Device Manager
. On Mac, you need to boot to macOS Recovery
and either reinstall the entire operating system or restore from a Time Machine backup.
Included in Windows is a handy system tool called CHKDSK that you can use to repair bad sectors on your SDHC card. Since the tool is already present on your system, it makes sense to give it a try. To repair bad sectors using CHKDKS:
Tip: The /R parameter tells CHKDSK to check the entire disk surface for bad sectors and repair them if possible.
- Type “cmd” in the search box on the taskbar and select Run as administrator.
- Enter the following command (make sure to replace X with the letter assigned to the SDHC card you want to fix) and press Enter:
- Wait for CHKDSK to finish. The process may take several hours depending on the size of your SDHC card.
