Restore SD card - causes and methods

The era of compact discs has passed for a long time. Now most of our contemporaries use USB-drives of different sizes. However, in addition to flash drives, there are other formats of carriers. For "heavy", capacious information intended Removable SSD-disks or HDD-hard drives, but data in compact and ultra-compact devices store SD-cards. Usually they are used in cameras, MP3-players, navigators and a variety of mobile phones. All these gadgets are "able" to hang, and then the SD card should be restored.

Such memory cards - creating fragile and delicate, so most often suffer from mechanical damage. In the "risk group" you can make a controller or a printed circuit board cards - they are damaged most often. SD chips suffer much less often. Data recovery from an SD card occurs not only because of mechanical breakdowns. Sometimes the failure is provoked by the owner of the device, incorrectly delivering the card from the slot. Sometimes the firmware of the SD controller flies, data is lost after formatting, or the owner forgets the password of his card.

Before describing the recovery of the SD-card, let's talk about the occurrence of this type of media. The format SD, or Secure Digital, was developed by Toshiba, Panasonic and SanDisk in 1999. The basis of the new format was the MMC map. The main difference between them is the special recording protocol, to which the rank-and-file Th user can not penetrate. Like a USB flash drive, the SD card is controlled by the controller. There is also a special mechanism on it that protects data from unauthorized reading. This mechanism illustrates the word "Secure" in the name of the card. In addition, the information on the storage medium can be protected with a password. There is a SD and a version called microSD. It is designed for especially small devices.

It is much more difficult to restore a card of this format than a regular flash drive. In the case of a USB drive, it is enough to read the controller number and find the required utility. It is impossible to restore the SD-card in this way, since it is almost impossible to count the number of its controlling microchip. However, there are several ways.

The easiest way to fix a map is if it is determined by the system. There are two programs for this: paid Easy Recovery and Free Inspector Smart Recovery. By running Any of them, you should select the required removable disk and the formats of the files written on it. The recovered data is saved in the folder that the user specifies. Both utilities restore and store erased or deleted data.

If you can not recover the SD card using these utilities, you should refer to the Windows tools. They will help when the files on the map are unavailable or poorly read. One of them can be found by selecting the "Properties" item in the context menu of the removable disk. On the "Tools" tab there are three tools, but you should use "Check". Push the button, put two checkmarks and run the function.

It should be remembered that each download degrades the state of the files on the SD. To restore the SD memory card without reading it many times in a row, it's worth creating an image of this media. The Flashnul utility will help. After creating an image, you can safely restore files without risking the card itself.
