Are you doubting the security of your data and want easy and effective methods to secure you data?If yes, then here we come to your rescue. The desired privacy can be easily achieved by encrypting your SD card. Here you will find a complete guide on how you can encrypt your SD card on Android and PC. So, let’s get started.
1. SD Card Lock and Encryption
SD card, or a Security Digital Card introduced by SD Association(SDA), Matsushita Electric, and Toshiba, is a non-volatile memory card. It was developed in portable devices like cameras, smartphones, camcorders, home theatre devices, set-top boxes, and video game consoles. Now, advanced smartphones use micro SD cards because the standard SD card seems to be quite large. The MicroSD card is six times smaller and two times thinner than the SD card. A MicroSD card is the variation of the standard SD card, and it can be used just like a standard SD card by using an adapter or an SD card slot. The microSD format is limited to a maximum of 1 TB.
SD cards come with different storage capacities, which also, to some extent, are concerned with their pricing. There are three different types of SD cards concerning storage. These are
• SDHC (High Capacity)
• SDXC (eXtended Capacity)
Before buying an SD card you should know if your device can support it or not, especially in cases of 64GB and 128GB cards.
SD cards have a small switch located on the side of the SD card, which is termed an SD card lock. The switch is very tiny, so you can easily find it if you look closely. You can slide the switch up towards the end with the notch to unlock it. To lock it, slide the card down. This induces write protection to the data inside the card.
When it is in the lock position, you won’t change or delete the card’s contents. Whereas, when you insert the card into your device, you will get an error message stating either the SD card is locked or unable to write. Most people use this feature in digital cameras to prevent the accidental deletion of photos. This locks the SD card rather than a single file or a folder. So it is not often used intentionally.
This write protection security method, i.e., SD card lock doesn’t make your data super secure. They are just there to prevent accidental changes like overwriting and formatting. If you are looking for protection and security, then encrypting your SD card is the best option.
But most of the time, while putting the SD card in or out of the slot, the switch itself moves, resulting in the locking of the SD card. There is no need to panic; slide the switch up. The SD card lock switch doesn’t usually slide itself, and it might be since it has loosened a bit, and that’s why it doesn’t offer friction. So, if you observe the sliding of the switch more often, then it is time to replace your card. You can also get this fixed from where you got the card. Also, if the card is old and worn out and you still want to use it, slide it to the unlock position and glue it there. Another way is to pull out the switch gently with the help of tweezers. While you pull out, make sure that the switch is in an unlocked position.
Also, if your switch breaks and it is in a lock position, then you can use an accurate piece of tape placed on the right spot. Any locked control of SD cards, floppy disks, and VHS tapes can be fixed this way.
It has been seen when the card is broken down and ripped apart, and the switch has no communication with the electronics of the SD card. It is considered to be just a plastic slider that doesn’t have contact with the internal of the card but impacts the card reader. When the SD card is placed inside the card reader’s slot, it senses the position of the switch with a small spring-loaded metal switch. If it is in the lock position, it will give the message of not writing on it.
MicroSD cards lack this switch. You can use a microSD card to SD adapter cartridge having a write protection switch. It will work exactly the way it works with the full-size SD card.
Here are some things you need to take care of while handling an SD card.
• SD cards are delicate and small so they can be damaged easily. Avoid their contact with fire, dust, water, and don’t let them be placed casually anywhere. Because once they are broken, there is no way to get the data back.
• Always keep your SD card in a secure location like a cupboard, drawer, or locker to prevent it from being stolen and for the safety of your data.
• You should always lock your SD card by pushing the switch to the left side. In this way, no one would be able to change or delete the data.
• Encrypting the SD card is the most reliable way of protecting information in your SD card. Only authorized access would be allowed in this case. All the steps to encrypt an SD card, whether you are using android or PC, will be covered in this article. So, keep reading!
