The memory card has basically been integrated into all aspects of life. The following system home mainly introduces the common skills of the memory card from the data erasing of the memory card, file encryption, and purchase. Tell you how to make your memory card more secure. The application of the memory card is extensive, and almost all digital products are inseparable from it. The memory card is not only a wide variety (including SD card, XD card, CF card, MMC card, memory stick, etc.), but its capacity is also increasingly quantified. In the eyes of most people, there seems to be no skill in using the memory card. This view is actually too one-sided. If you really want to use the memory card and make full use of its functions, you can't do without the cooperation of related software. Here are a few simple examples that explain the techniques for using a memory card, and I hope to help and inspire you. For the memory card completely "amnesia"; colleagues borrowed a digital camera from Xiao Ming, Xiao Ming copied the contents of the camera memory card to the computer, then cleared the contents, and then loaned the camera to a colleague. After a while, Xiao Ming inadvertently found that colleagues were browsing the photos they had deleted on the computer. Xiao Ming felt a little angry. It seems that the colleague may be out of curiosity, using anti-delete software to recover deleted photos from the memory card. It seems that before you borrow digital equipment, you must completely remove the contents! Using the Digital Media Shredder (DMS) software, you can make the memory card completely "amnesia" to avoid data leakage "cups". Download address: http://www.safeit.com/downloads/DigitalMediaShredder.exe. Click the “Set” button at the bottom of the DMS main interface. In the Settings window (Figure 1), select the preferred smash algorithm. Some strong data erasure algorithms are preset in the list, and the desired deletion algorithm is selected. The description of the algorithm is displayed in the "Information” column. Check the “Format after successful smashing” option to indicate that the memory card is formatted after the data has been completely deleted. Then connect the memory card to the computer, find the corresponding memory card device name in the DMS main interface, and click the “Start” button in the “Start” column to start the data erase operation on the memory card. The DMS will display the progress of the data deletion operation, the time spent, the remaining time, the cleaning speed and other parameters in real time. When the cleaning is completed, your memory card will be completely “brainwashed”, even if someone else gets the card, it can't illegally recover the data. Memory card encryption and decryption, I want to fully automatic Lao Li is the editor of a website, which has many important files stored in its mobile phone memory card. In order to be safe, Lao Li decided to encrypt it. However, the commonly used encryption software is cumbersome to use, and Lao Li is not very easy to use. Lao Li thinks that if the encryption and decryption operation can be made transparent, when the file is copied between the memory card and the computer, the file encryption or decryption processing can be automatically realized, can it be simplified? With the green software MysecureDrive, the above problems can be solved. Download address: http://www.mysecuredrive.com/. When running MysecureDrive for the first time, you need to enter the password in the authentication window (Figure 2). To be on the safe side, you can also click the “Use On Screen Keyboard” button to complete the password input operation using the on-screen keyboard. Activate the automatic encryption function by checking the “Encryption Mode” option in the right-click menu of the MysecureDrive icon in the system tray. MysecureDrive can monitor the file copy operation in the background. When the user finds that the file is copied to the memory card, it can intercept it, encrypt the original file with 256-bit AES encryption algorithm, and then put it on the memory card. When the file is encrypted, MysecureDrive can automatically add an encryption tag to its icon. When copying an encrypted file from a USB flash drive to your computer, MysecureDrive can automatically decrypt it so you can view the contents of the file directly. For ease of use, you'd better copy MysecureDrive to a memory card or USB stick, which is more convenient to use. Easy & ldquo; physical examination & rdquo;, help you buy a high-quality memory card Xiao Li to the computer city to hang out, see a company's memory card is very cheap to sell, Xiao Li feels very cost-effective, I bought an 8G memory card. However, it took a long time to use the memory card and the problem could not be used normally. The files stored in it could not be retrieved. This makes Xiao Li very depressed. It seems that it is necessary to check the physical fitness of the memory card when buying a card later. With Check Flash's green software, Xiao Li is no longer afraid to buy inferior memory cards. Download address: http://mikelab.kiev.ua/PROGRAMS/ChkFlsh.zip. Select the drive letter corresponding to the memory card in the <quo;Drive” list in the main window of Check Flash (Figure 3), and select the item “As physical drive (NT-based system only)" in the “Access type” column. And treat it as a physical disk. In the "Action type" column, the commonly used detection means are listed. Generally, the "Write and read test" item is selected to read and write the memory card. In order to improve the accuracy of the test, it is best to select the "Full pattern set" option under it and use the complex data format for reading and writing tests. Select the type of test in the "Test length" column. It is recommended to select the "Burn it!" option to perform an uninterrupted test on the memory card until the user manually interrupts the test. Of course, you can also choose other test types, including single test, cycle test, non-stop test and so on. Click the “Start!” button at the bottom of the window to perform the test. When the detection is completed, if all the green squares are displayed in the “Drive map” panel, the memory card “health status” is good. If a red square appears, it indicates that the memory card is physically damaged. A yellow square indicating that the portion of the memory card has been corrupted.
