The memory card, also known as the SD card, is a new generation of memory devices based on semiconductor flash memory, which is widely used in portable devices such as digital cameras, personal digital assistants (PDAs) and multimedia playback. And so on. The SD card was jointly developed by Panasonic, Toshiba and SanDisk in the United States in August 1999. The SD memory card, which is the size of a stamp, weighs only 2 grams, but has high memory capacity, fast data transfer rate, great mobility flexibility and good security. Today, the syllabus network Xiaobian is about to talk about the memory card related knowledge, including: memory card data loss solution, classification, four causes of memory card failure, memory card unrecognized solution.
Memory card data loss solution
1. Insert the sandisk memory card of the deleted photo into the card reader and connect it to the computer to confirm that the computer can recognize the storage device normally.
2. Open the computer and enter the main interface of the tool, select the sandisk memory card partition you need to restore, and then click to start scanning.
3. Enter the data scanning phase and scan all the data in the hard disk. If the data is large, the scanning time will be long. please wait patiently!
4. After the scan is completed, multiple folders will appear on the interface, and the photos will be deleted. After screening, check the photos you want to restore.
5. Click “Restore” to enter the file recovery path setting. After setting the storage location, click "OK" to resume.
Memory card classification
1, MMC card
The MMC card (Multimedia Card) is translated into a “multimedia card”. Is a flash memory card standard. Mainly for digital video, music, mobile phones, PDAs, e-books, toys and other products, its size is only 32mm × 24mm × 1.4mm, weighing only 1.5 grams. However, due to the lack of support from consumer digital manufacturers, there are not many products that can use MMC memory cards in the digital product market.
2, SD card
The SD card (Secure Digital) was jointly developed by Panasonic, Toshiba and SanDisk in Japan. It measures 32mm × 24mm × 2.1mm and weighs only 2 grams, but it has the characteristics of large capacity, high data transmission rate and good flexibility. The SD card structure ensures the security of digital file transfer and is easily reformatted, so it has a wide range of applications. Many digital cameras use SD as a storage medium. This also makes the SD card the most widely used memory card.
3, Mini SD
Mini SD is developed from SD card, and the performance is not much different from the traditional SD card. Like the SD card, the Mini SD card has a hardware data write-protect switch to avoid the risk of accidental deletion of stored content. However, the Mini SD card is smaller in size, only 21.5 mm × 20 mm × 1.4 mm, which is 40% less than the SD card. It can be used with a dedicated riser card and is fully compatible with standard SD card slots. On the other hand, the most important thing is that the Mini SD card uses a low-power design, so it is more suitable for mobile communication devices than SD cards. Currently, it is mainly used in information terminal devices such as mobile phones, PDAs, and handheld computers.
4, TF card
TF card, also known as T-Flash card, full name: TransFLash (aka: Micro SD), is a very small flash memory card, jointly developed by Motorola and SANDISK. It has a positive and small advantage, mainly for mobile phones, but with the ever-increasing capacity, it slowly began to be applied to a wider field. At the same time, it can also be connected to the SD card slot with an adapter, and has a large capacity.
5, memory stick
The memory stick is called Memory Stick, which is a mobile storage medium developed by Sony Corporation of Japan. This storage device looks like a chewing gum and is highly compatible. Later, Sony reduced the volume to about 1/3 on the basis of the memory stick, and designed and manufactured the memory stick Duo. This memory stick Duo is easy to use in quite small mobile phones and digital cameras, as well as in various electronic products such as mp3 players.
6, PCI-e flash card
PCI-e flash card (PCI-Express) is the latest bus and interface standard. Its original name is "3GIO". PCIe belongs to high-speed serial point-to-point dual-channel high-bandwidth transmission. The connected devices are allocated exclusive channel bandwidth. Shared resources, mainly support active power management, error reporting, end-to-end reliability transmission, hot swap and quality of service (QOS). The principle is based on NAND-type flash memory.
7, SM card
The SM (Smart Media) card is a type of micro memory card, similar to an SD card. Published by Toshiba Corporation in November 1995. SmartMedia uses a 22-pin interface that uses both physical and logical formats. The physical format ensures compatibility between different device models and is a must for system and control vendors. The physical format is based on the FAT standard for ATA and DOS files, so that it is easier to exchange data between different systems, but the configuration of the physical format will vary in page size, depending on the type of memory and the capacity of the memory card. As for the logical format, the DOS-FAT format is used, which is the cylindrical head sector parameters, the main sector and the partition. SmartMedia also has two operating voltages of 3.3 volts and 5 volts, but it is not possible to support both voltages simultaneously. However, there are no products using SM memory cards in the digital cameras that are now available.
8, CF card
CompactFlash (Flash) was originally a data storage device for portable electronic devices. As a storage device, it revolutionized the use of flash memory. It was first produced and standardized by SanDisk in 1994. Currently, its physical format has been adopted by a variety of devices. However, CF card capacity is limited, and its capacity increase cannot keep up with the development of digital camera pixels. Compared with other types of memory cards, the volume is too large, and the operating temperature is generally 0-40 degrees Celsius, which limits its performance.
The XQD memory card is a memory card developed by Sony Corporation. Its size is much smaller than the current CF card, only about half its size. However, the XQD memory card retains the CF card for fast and stable reading. In addition, the XQD memory card also uses a scalable high-performance interface. Its read and write speeds reached 125 megabits per second.
9, XD-Picture Card (xD) card
The XD-Picture Card (xD) card is a memory card jointly launched by Olympus and Fuji. It has an extremely compact shape and is 20mm × 25mm × 1.7mm in size and weighs only 2 grams. Its read and write speed can reach 5MB/S and 3MB/S. XD cards were first used in Olympus and Fuji digital camera products. Although their performance can meet the requirements of large data writes and lower power consumption, the relatively high price has greatly limited the development of XD cards. At present, Olympus and Fuji's digital cameras no longer only use XD cards as storage media.
10, M2 card
The M2 card is a new memory card Memory Stick Micro (M2) jointly launched by Sony and SanDisk, which was launched in March 2006. This M2 card is designed with ultra-small circuit design and is designed for large-capacity and small-volume mobile storage. It weighs only 16 grams and has a size of only 15×12.5×1.2mm. It is about one-fourth the size of the Memory Stick Pro Duo.
Four causes of memory card failure
1. The SD card/memory card data is accidentally deleted and misformatted.
This is mainly due to improper personal operations. Mobile phones and cameras are becoming more and more intelligent. Since the buttons of mobile phones have been replaced by smart large screens, the screen sensitivity of these mobile devices is getting higher and higher. When personal use is not noticed, it is easy to delete the data in the memory card or to format the entire card. Turn.
2, SD card / memory card can not be formatted
There are many reasons why the memory card cannot be formatted: first consider whether it is infected with a virus; after eliminating the virus factor, see if the mobile phone and camera are overheated for a long time (uninterrupted use), frequently read and write, and the card temperature is too high. It is easy to burn the card; the mobile device and the memory card are not compatible; the memory card is physically damaged.
3. After the SD card/memory card is connected to the computer, the prompt needs to be formatted.
This may be caused by improper use. If there is no "safe pop-up hardware device" after using the memory card, this may occur in the next use; the card reader problem (such as poor card reader contact); the memory card The file system is not recognized by the operating system or is corrupted inside the memory card.
4, the card reader can not read the SD card / memory card
It may be caused by poor contact between the card reader and the memory card, or damage caused by the memory card.
Memory card unrecognized solution
1. Shut down and take out the SD card. Check if the card slot and direction placed on the SD card are correct.
2. Re-insert the SD card and restart the machine to try.
3. If the SD card is still not recognized, it is recommended to place the SD card in other mobile phones to see if it can be recognized normally.
4. If it can be recognized, please back up the contents of the SD card, format the SD card and place it in your mobile phone again.
5. If it is still unrecognizable, it may be that the SD card is not compatible with your device. It is recommended to try another SD card instead.
6. If it is invalid, please update the phone system version: Settings - About mobile phone (about device) - Manual download update / Automatic download update (software update / system update - update). Note: Back up the data in the device before upgrading.
