SD memory cards are one of the best and cheapest ways to store data. We can access this data anytime, on any computer or device. You can recover data from SD memory cards on Android smartphones, tablets, PC, laptops, Mac, DSLRs, Camcorders, music players, digital cameras, and pretty much every portable device that supports SD memory cards. As you are here, it's likely that you have lost data from your SD memory card. Read on to recover lost or deleted data from all types of SD card.
SD Memory Cards
SD (Secure Digital) cards are memory cards primarily used in digital cameras and other portable devices. They are usually tiny, portable, easy to use, inexpensive, and secure. The first SD memory cards were announced in 1999, and after 23 years of evolution, they are now available in many capacities, speed classes, and bus interfaces. SD memory cards pack many qualities. They are simple, inexpensive, tiny, portable, and quite secure.
If SD memory cards have so many qualities, what's the catch? The biggest downside of an SD memory card is that they are not very durable. They easily get damaged or corrupted. Not just that, there are many other data loss risks such as accidental formatting, and other errors associated with SD memory cards. Thankfully, recovering lost data from an SD memory card is possible. In this article, we will discuss various data loss scenarios, but before that, let's understand what happens when data is lost from an SD memory card.
What Happens When Data Is Lost From an SD Memory Card?
When data is lost from an SD memory card, most assume that deleted data is lost forever and can't be recovered. But the reality is different. What if we tell you that the lost data is still available on your SD memory card? Yes, it's true. Here, the data has been moved to another sector of the SD memory card. So if the data is still there, why is it not visible? It is because the sector where the data now resides is not readable by your device.
The system moves the deleted data to another location and marks the space available for new data. The deleted data remains there until new files overwrite this data. This is why it is advised that you should immediately stop using the SD memory card in the event of data loss. Doing so will prevent the deleted data from getting overwritten, and you'll be able to recover that data. We hope now you have a clearer idea about what happens when data is lost from an SD memory card.

Your SD memory card got broken or scratched
Due to their small size and sensitivity, SD memory cards can easily get broken or scratched. You need to handle them carefully to save them from any physical damage. You may wrongly insert an SD memory card into the computer, scratching the connectors present at the back of your SD memory card. Some users have a terrible habit of putting SD memory cards into the back pocket of their jeans. The cards can easily bend or break into two pieces with a bit of extra weight.
In logical data loss scenarios like the ones mentioned previously, there are comparatively high chances of data recovery. But if the SD memory card has been broken or scratched, the chances of recovery become remote. Also, you may need to contact a data recovery service company specializing in physical data loss scenarios.
Permanently erasing or wiping SD memory card
When you format your SD memory card, the data does not get permanently erased. It can be easily recovered using a recovery software. However, some users want to format their SD memory card in a manner that data recovery is not possible by any means. In those scenarios, they use professional data erasure software. The data erasure software wipes an SD memory card beyond the scope of the recovery. They do it by overwriting the data multiple times with random data.
It completely destroys the data leaving no chances of data recovery. If you have permanently erased or wiped your SD memory card with the help of a data erasure software and now want to recover the data again, it is next to impossible. Still, if you want to try it, get in touch with a data recovery services company, and they will check if there is anything they could do.
