Tracy King updated on Dec 05, 2018 to Partition Master | How-to Articles

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.

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;
