Answer. Yes, you can repair your SD card without formatting it. You can do this with a data recovery tool. If your SD card is corrupted, then the first thing you should do is to not save any more new data on it. Now you ask how to retrieve all the previous data from the card? Follow the guidelines given below that will help you fix your corrupted SD card, without having to format it.


Today's world is so that all of us are always in need of more and more storage space. We have all sorts of storage devices such as pen drives and SD cards. Despite that today mobile phones, laptops, and computers come with so much internal storage, one can never seem to have enough of it.

But another persistent problem that mostly tags along with all these storage devices is that they crash. Every one of them at least once in their lifetime will crash, taking alone all your data to a world unknown.

Dealing with a corrupted memory or SD card is no child's play. Since we believe the data inside of it to be important, be it personal or professional, recovering it becomes an important task.

Any online forum that you go to, you will find yourself surrounded with hundreds and thousands of questions about the same thing – how do I fix my corrupted SD card or what the common signs of a corrupted SD card are.

Part 1. What are the common signs of SD card corruption?

Almost everybody you ever happen to come across not only knows what an SD card is but will have used or are still using one of these. And not so surprisingly, some of them must have also faced the problem of a corrupted SD card.

An SD card is more often than not used in mobile phones and cameras to keep a better record of your information. If you are somebody who has a lot of data to store especially in terms of photos and videos, then getting an SD card is probably the best idea.

However, since your SD card is full of so many important things, one can only imagine how difficult it is when your SD card gets corrupted.

Here are some of the most common signs of SD card corruption that you should look out for:

In some cases, when your SD card is almost out or is about to corrupt to its peak, then you will see your electronic device's screen as black. It is like one day you open your device and there is nothing on the screen, except that it is black, then more probably than not, it is the fault of your SD card.

When an SD is corrupted partly and is on the verge of breaking through completely, you will start seeing messages such as 'access is denied' and similar ones.

In case you are unable to save new files into your SD card, also called write failures, then it might be a sign of a corrupted SD card. Also, if you are unable to read an SD card and not see any of its components, then it also points towards a corrupted SD card.

If you have certain things in your SD card and also some folders, but your SD card does not show anything in the card or shows wrong or incorrect bytes, then your SD card is corrupted.

When an SD card is corrupted, the most thing you will notice is that your SD card will start missing out on certain files now and then. You might see a file one day but it disappears the next day and returns a few days later, then it is a clear sign of corruption.

Another common thing that happens in the case of a corrupted SD card is that your computer does not recognize your SD card.

If you witness any unknown files in your SD card, then you should know instantly that your SD is corrupt and needs to be fixed.

Part 2. What are the 8 ways to fix a corrupted/damaged SD card?

Here are the 8 ways in which you can fix your corrupted/damaged card:

Fix 1. Change a card reader, adaptor, or a USB port

Many times you will see that power or connection issues cause card problems. The primary thing to do is to exclude exterior factors.

You should try reconnecting a different USB port or a new adaptor or another computer to see where the actual problem lies. If your SD starts to work normally after a few attempts, then it was probably nothing but a poor connection.

To prevent future data loss, you should shift all your data to other safe places such as cloud storage.

Fix 2. Run windows repair tool

If the primary fix did not turn out to be exactly very helpful, then you should try this second fix with the native Window check & repair tool to fix your corrupted SD card:

run windows repair tool

Fix 3. Change a drive letter

In case your SD card is not assigned a drive letter by the Windows system or it is conflicted with other drives, then your SD card will start acting like it is corrupted, and as a consequence, becomes unreadable.

Your computer comes with an inbuilt Windows Disk Management program and you can use it to change a drive letter this time.

Here are the steps to how it is done:

change a drive letter

Fix 4. Run CHKDSK to check and repair SD card bad sectors

Like any other removable storage device, the SD card has a limited lifespan. Bad sectors tend to grow once it had been used for a long period. A good way to find errors in the SD card file system is through CHKDSK cmd. Also, if you are looking for a way to repair your SD card without formatting it, then these are the steps you should follow:

run chkdsk to check and repair sd card

check corrupted sd card

Fix 5. Reinstall the SD card driver

If you cannot see your SD card mentioned anywhere in your Windows Explorer or your Windows Disk Management, then the chances of your SD card not recognizing it is high. To counter this, you can try to reinstall the SD card driver to make it reappear in your Windows Device Manager.

Here are the steps you can follow to carry out the same:

reinstall the sd card driver

Fix 6. Format a RAW SD card

If you see your card displayed as RAW in Windows Disk Management, then you need to format your card with a proper file system like FAT32 or NTFS.

Fix 7. Format a half capacity SD card

There are times when you will see that your SD card is showing only half of what its actual capacity is. In such a case, you will have to restore it to its full capacity by formatting the half capacity SD card.

You can do so by going with Disk Management or Windows File Explorer.

Fix 8. Create a new SD card partition on unallocated space

Sometimes a RAW SD card does not show up on your computer. This might also happen when your SD card turns empty. If you want to make your SD appear normal on your computer, then you have to create a partition manually. This partition will make Windows recognize it.
