Common Failures

● A photo or other data is deleted directly from cameras, mobile phones and computers (some important data is deleted without backup)

● Prompt of "not formatted" (prompt of formatting after inserting electronic equipment)

● Prompt of "cannot be formatted" (computer pops up error prompt "cannot be formatted")

● Not recognized on cameras, mobile phones and computers (not recognized on electronic equipment)

● The memory card is formatted accidentally (the button of formatting is pressed accidentally)

● The size of the memory card is incorrect (the size of the file is not realistic and the total size of the memory card is obviously inconsistent)

● The memory card is damaged by external force (the memory card has visible deformation or crack)

● The memory card can be identified normally, but cannot be backed up (data can be seen but will jam during reading and writing)

● The memory card is full of garbled texts when opened (all data is missing, leaving only a pile of garbled files)

Processing Method

Among numerous failures, there is only one situation that we suggest you try to recover by yourself, and we suggest you leave the remaining situations to a company specifically engaged in data recovery for processing (we will, in the paragraphs below, explain the reason why you should leave the remaining situations to a data recovery company, rather than try to solve them by yourself). The only one situation is that the Memory card does not suffer hardware damage, such as careless deletion of data and no writing of any data, or careless formatting of the Memory card, and then you can try to recover data with data recovery software. The commonly used data recovery software includes EasyRecovery, WiseRecovery and Disk Drill, and it is necessary to pay attention to and identify their advantages and disadvantages in use. Of course, before trying it out on your own, there are certain steps you must pay attention to, otherwise, data may not be recovered and your Memory card may be further damaged. The first step is to make a complete copy of the Memory card according to the current state to another Memory card (not the copy and paste through Windows, but completely copy every byte of the Memory card through software, which can be done only when the Memory card does not suffer hardware damage). This step requires a writing protection device (Write Blocker), so as to prevent change of the data. Then you can use the data recovery software to recover the copied Memory card, but the recovered data must not be put back to the original Memory card. It is because, in this case, overwriting and recovering will occur simultaneously and the recovered data cannot be opened. So keep in mind the above steps. For anything you don’t understand, please feel free to contact us for details at any time, and we are willing to answer questions for each customer. But sometimes the data recovery software cannot solve all problems, and in most cases, you have to rely on data recovery engineers for analysis. For example, why the rescued data does not have directory or file name or not a byte of data can be rescued. At this point, you don't have to give up and you can contact us. We will try to rescue your important data.

If the Memory card suffers hardware damage, and because there is no professional technology or equipment, you might truly make the Memory card worse or the data lost forever through aimless attempts. The memory card is limited in erasing and writing times because scanning will read the information of each unit of the memory card crystal, and constant reading will make the position worse and worse. When reading bad areas, the memory chip of the memory card will become worse and worse due to constant forced reading, and the number of bad areas will continue to increase. In some cases, the whole chip will be completely damaged and data loss will be serious.For example, there is a bad sector on the Memory card, but you use the data recovery software to scan the Memory card, and then you will find the Memory card is getting slower and slower, even a crash. This is because scanning is to read the information of each sector of the Memory card. When it comes to the bad sector, it will get stuck and reading cannot continue. The magnetism of the Memory card will become increasingly weaker due to continuous forced reading, and the number of bad sectors will increase. At this moment, it is quite usual that a friend or someone knowing much about computer will tell you to recover the bad sectors with special software. The result, of course, will be in vain. This is because the software doesn't fix the bad sectors at all but marks areas with bad sectors as no longer in use, and by that time, things are worse than they originally were. If you take the Memory card to a professional data recovery company at this moment, the failure detected will be more serious than it initially was. Actually, if you want to recover the data from the Memory card with bad sector failure, the data can be smoothly recovered with corresponding equipment support, with relatively low price and high degree of data integrity. But if you make forced reading, scanning and bad sector recovery on your own, the Memory card will become more damaged, even the magnetic head used to read and write data might fail. Then the price will be high and data integrity will be reduced. In individual cases, the disk might be scratched, leading to serious data loss. In the past recovery cases, many users would constantly try to read the Memory card on their own, which would have a great impact on the subsequent data recovery. It is therefore suggested that non-professionals should minimize aimless operation. There is only one chance for data recovery. Please make backup and find a professional data recovery company to help rescue your valuable information.

Solutions

If the data in an Memory card needs to be rescued in case of failure, the first thing to do is to find out whether the Memory card failure is a logic failure or a hardware failure, which can be done through customer’s detailed description and detailed detection with professional devices. Commonly used professional devices include PC-3000 Flash, FlashExtractor, Spider Board Adapter, dust-free laboratory, microscope and oscilloscope. These professional devices and tools can help us accurately detect specific Memory card failures without damaging the Memory card. The Company uses corresponding technology to solve these failures, and will be able to normally extract the raw data from the Memory card and recover the data as required by customers through analysis and reorganization. As a result, aimless operation will cause unnecessary damage to the Memory card and affect Memory card data salvation.

Use professional equipment to retrieve data from memory cards

Memory cards generally use Flash chips as storage media. When hardware failures occur, we can only save data by directly accessing its internal chips. As long as the internal circuit of the memory card is in good condition, there is a great chance to save the data inside. First, we should remove the protective layer of the internal circuit of the memory card to clearly see the distributed data access points. By connecting these access points with professional equipment through tools such as Spider Board Adapter, the detailed information of the chip and the original data can be extracted. Then, the extracted original data can be recombined on professional equipment through the corresponding checksum algorithm to read the data of the memory card.
