recover raw sd cardWe often use SD cards to back up important files and information that we need on the move. So it can be frustrating to find out that your computer is refusing to let you access the card because it has gone into a RAW state. It might seem like you’ve lost all your data, but there are ways to successfully execute a RAW SD card recovery.

We’re going to get into all of the steps involved in that process in this article. Before that, let’s understand the problem a little better.

What Is a RAW SD Card?

A RAW SD card is one that appears unreadable by a computer. Essentially, you have the experience of not being able to access the files that you’ve stored on the SD card.

Internally, a RAW SD card is one whose file system has become damaged. This can happen due to a whole host of reasons. Whatever the cause might be, the operating system of your computer will be unable to read its contents.

SD cards in this state are called RAW because they’re in a state where the file system is in a completely raw or unusable state. You need to take some action to restore it to a readable format like FAT32 or NTFS.

How SD Cards Become RAW

If you find that your SD card is RAW, then there are a few common culprits behind that. That includes:

Reason Description
📟 Improper usage The file system has become corrupted due to improper startup or shutdown, hardware failures, etc.
🦠 Malware or virus The file system of your SD card is missing entirely due to the effects of a piece of malware, hardware issues, etc.
📲 Device compatibility The SD card’s file system is not compatible with the computer that you’re working on. This can be the case if either the card or computer are an old device.
📵 Failed formatting The file system formatting of the SD card is not done properly. This usually occurs due to bad formatting procedures and improper updates.

If you find that your SD card is in this condition, your operating system will usually give you the option of formatting it. That will make the card readable again, but you will lose all your data. The good news is that there are ways to fix a raw SD card without formatting it. Let’s find out what they are.
