1. A preliminary study on the RAW phenomenon of SD card
In the fields of photography, videography and data storage, SD cards (Secure Digital Card) play an indispensable role. However, when the SD card status suddenly changes to RAW, many users will feel at a loss. RAW status means that the file system is severely corrupted and the operating system is unable to recognize the data structures and file information inside the card. In this case, only garbled files or folders may be displayed in File Explorer, and you may not even be able to access any of the contents of the SD card.
2. Causes of SD card RAW
There are various reasons for SD card status to become RAW, the most common of which include improper operation, file system corruption, virus infection, and hardware failure. Improper operation may be the wrong file system type or partition parameters selected during the formatting or partitioning process; File system corruption may be caused by frequent reads and writes, sudden power failure, or pulling out the SD card. Virus infection may cause the file system structure to be tampered with. Hardware failures can be caused by the quality of the SD card itself or long-term use.
3. Data recovery plan
When the SD card status changes to RAW, the most important thing is to take steps to recover the data as soon as possible. Here are two possible data recovery scenarios:
Use professional data recovery software
For most SD cards in RAW state, using a professional data recovery software is an efficient and safe method. For example, DigitalQuest software is capable of scanning SD card in RAW state and trying to recover files in it. When using this kind of software, you need to pay attention to choosing the right SD card device and follow the operation steps of the software to complete the data recovery.
With the help of a file system repair tool
Apart from professional data recovery software, you can also try to use a file system repair tool to recover SD card in RAW state. These tools can usually detect and fix errors in the file system to restore normal access to the SD card. It should be noted that when using such tools, you need to read the operation steps carefully and strictly follow the steps to avoid data loss.
Fourth, the strategy to avoid the RAW state of SD card
In order to avoid the SD card status from becoming RAW, the following strategies can be adopted:
Standardize operations: While formatting or partitioning the SD card, make sure to select the correct file system type and partition parameters. Avoid abrupt power failure or unplugging the SD card during the SD card reading and writing process.
Regular backups: Back up your important data from your SD card regularly, just in case. You can choose to store your data in other storage devices, such as external hard drives or cloud storage.
Protect against viruses: Install and update anti-virus software and scan your SD card regularly to prevent virus infection.
Check the quality of the SD card: Choose well-known brands and reliable quality products when buying SD cards, and avoid using inferior SD cards.
5. Summary and enlightenment
SD card status changing to RAW is a common but tricky issue. Understanding the causes and taking appropriate data recovery plans is critical to keeping your data safe. By standardizing operations, taking regular backups, preventing viruses, and checking the quality of the SD card, you can effectively reduce the risk of the SD card status becoming RAW. During the data recovery process, choosing a professional data recovery software or file system repair tool can improve the success rate of data recovery. At the same time, we should also realize that data recovery is not a panacea, so when you encounter SD card RAW issues, you should take measures as early as possible to avoid data loss.
