A Little Advice – Get a Replacement

There are chances that the warranty of your corrupted USB drive or SD card is still valid. So, if your storage device is frequently giving you problems, it’s advisable to get a refund or replacement. It could be the case the storage media is permanently damaged already.

We’re recommending this as it’s not worth putting your faith in an SD card/flash drive that’s showing signs of unreliability again and again.

The solutions for repairing SD cards and flash drives might be similar, but they are different kinds of hardware. For SD cards, there could be several issues preventing you from accessing data on your computer.

While most of the modern laptops and 2-in-1 devices feature an SD card slot, the same is a no-show on desktops. That’s why people take the help of cheap external card readers which run into problems more often.

External card reader not working

Sometimes, it might be the case that your card reader is broken and you’re blaming your innocent PC. Maybe, the memory card reader isn’t getting enough power from the USB port, or no power at all if its USB cable is damaged.

It could also be the case that you’re using an old card reader while trying to access your card. It may not support higher capacity SDXC, newer UHS-I, or UHS-II interfaces, or may not work on the latest versions of operating systems.

Check if your microSD Adapter is Working Properly

When you’re trying to connect a microSD card using a MicroSD to SD adapter, make sure the adapter is working fine. Also, there is a tiny slider present on the SD card adapter, when turned on, allows the data on the card to be read-only. Check if it’s in the correct position.

Check if your SD card is Damaged

If you are one of the people who use their memory cards irresponsibly, there might be one day when it will get damaged permanently. Improperly installing and removing the SD card from the card reader can hurt its golden connectors and even make it unusable. So, if your card is not getting recognized, check the connectors.

Note: Please note that the SD card and USB repair methods described above are general ways to fix a device. Due to some device-specific issues, there could be cases when these steps might not be useful.
