Micro SD cards are small, secure digital (SD) memory cards that provide storage to an array of devices such as mobile phones, PDAs and cameras. Micro SD cards may be secured with a password to protect the contents of the card. However, as users will do, occasionally a micro SD card password will be forgotten or lost. Password recovery procedures can save the user the time and hassle of reformatting the micro SD card, which will also result in data loss.
