![]() ![]() Method 3: Change the Drive Letter of the SD Card You can also try the /f parameter, which fixes errors but doesn’t recover readable information. The /r parameter tells CHKDSK to locate bad sectors and recover readable information. Agree if asked whether you would like to force a dismount of the SD card.Type the following command and press Enter (replace X with the drive letter of your SD card): chkdsk X: /r.Press Windows + X and select Windows PowerShell (Admin).Write down the drive letter of your SD card.Open Windows Explorer and select This PC from the left panel.Using a command-line tool to fix SD card corruption may understandably feel intimidating, but there’s really nothing to it as long as you follow our instructions: Method 2: Use the CHKDSK Command to Fix File System ErrorsĬHKDSK is a command-line tool in Windows that you can use to check an SD card for disk errors and bad sectors and repair them if possible. ![]() If that doesn’t help, then you should check the integrity of your operating system because your issues could be caused by missing or faulty drivers. If you can access the content of your SD card just fine from another device, then there’s something wrong with your computer or its memory card reader.Īgain, the simplest solution is to get a new memory card reader and try again. If you don’t have access to another computer, you can use a smartphone or a smart TV with an SD card slot. To rule out the possibility of your computer being the cause of the corruption, we recommend you start by connecting your SD card to another device. Method 1: Access the SD Card from Another Device That’s because there are many effective methods for fixing corrupted SD cards, and we describe the most effective ones below. When an SD card becomes corrupted, it doesn’t automatically mean that all files stored on it are gone. Other reasons why corrupted SD card recovery is a hot topic include bugs in software applications resulting in logical damage, unintentional formatting and file deletion, as well as controller failures and driver problems. That’s why it’s important to use brand-name SD cards and memory card readers instead of their budget no-name counterparts. When this voltage can’t be reliably provided due to power outages or hardware issues, read/write operations are unlikely to finish successfully. Just like all storage devices, SD cards require a certain voltage to operate correctly. The same goes for various shady software applications that exist just to earn their creators money without providing anything of value in return. What’s more, most people don’t understand that some devices support only certain file systems, and that attempts to use an SD card with a device that doesn’t support it may result in data becoming corrupted.įrom common viruses to stealthy trojan horses to sinister ransomware, there are many strains of malware that can infect SD cards and corrupt data stored on them. All too often, users are too lazy to properly eject their SD card before physically removing it from the memory card reader and possibly interrupting running read/write processes. The single biggest cause of logical damage are users themselves. How Do SD Cards Get Corrupted?Īs we’ve already stated, SD card corruption is caused by logical damage, but what are the causes of logical damage? There are several that you should know about: Cause In reality, most original files are usually still physically present and recoverable using the right techniques and software solutions. Such SD cards typically appear as if there were no data stored on them at all. In extreme cases, SD cards that have become corrupted may not even be accessible.
