How To Decrypt A Micro Sd Card
Nowadays, most smartphones, digital cameras, and other portable storage devices provide encryption feature, by which users are able to encrypt the data and files stored within. Encrypting materials on an SD card would efficiently protect privacy and ensure data security.
SD cards can now be encrypted. If you encrypt the SD card however, it is using software encryption which will be much slower and will lean on the CPU constantly. If you do use SD card encryption don't expect apps or maps to work well from the SD card so put them all on internal storage. Also, record any high res video to internal storage to avoid issues. If you use a USB flash drive or SD card brand from Kingston, Sony, Samsung, SanDisk, and any brand of USB flash drive or SD card, the program will be well recognized and run on Windows10 / 8/7 / Vista / XP system. One day you want to decrypt a protected USB flash drive or SD card file, you only need a simple mouse click. If you perform a reset on your Lumia 950 while the encryption is on, the data and its contents that ties your device and SD card will be inaccessible. Just like Philip Anderson's Mother's Son said on the previous post, you can only decrypt a device on the device that encrypted it, and entering the correct password or key when the device is powered on.
However, forgetting the encryption password could definitely kill you, even trying to format SD card that won't help to decrypt it, because Windows won't give the permission. Usually, it sends a security error that prevents the format.
If you want to decrypt and format encrypted SD card, first, you must wipe the card completely along with the encryption information by using Diskpart utility, then use EaseUS partition magic to do the format.
Make sure your SD card is correctly connected to a Windows PC and it is recognized as a removable storage device. For example, Windows detects your SD card as drive G:.
# 1. Use Diskpart utility to remove SD Card encryption
1) Press 'Windows-R' and type 'cmd' in the Run box (without the quotation mark);
2) Press 'Enter' key to open a new command prompt window;
3) Click inside the command prompt window, and type 'diskpart', then press the 'Enter' key to display volume information for all of the hard drives installed in the system;
4) Enter 'select disk g' at the prompt (g is the disk number of the encrypted SD card);
5) Type 'clean all' and then press 'Enter' key.
After some minutes, Diskpart utility will finish wiping all data on the encrypted SD card. If you have saved some useful data on the SD card, refer to recover data from SD card with powerful data recovery software. Now you can move on to the next step to format the card.
# 2. Use EaseUS Partition Master to format SD card after decryption
Download EaseUS partition manager software to your PC and use its format partition feature to format the SD card after removing the encryption with ease.
Step 1: Launch EaseUS Partition Master, right-click the partition on your external hard drive/USB/SD card which you want to format and choose the 'Format' option.
Step 2: Assign a new partition label, file system (NTFS/FAT32/EXT2/EXT3), and cluster size to the selected partition, then click 'OK'.
Step 3: In the Warning window, click 'OK' to continue.
Step 4: Click the 'Execute Operation' button in the top-left corner to review the changes, then click 'Apply' to start formatting your external hard drive/USB/SD card.
After done with the two steps above, you've now successfully decrypted SD card and formatted it as new.
