The RAW stands for no file system, corrupted file system or unknown system in a hard drive partition or external storage device such as external hard drive, USB flash drive, memory card, etc. The RAW file system is not readable or writable. If your hard drive becomes RAW, you won’t access the files stored on the hard drive. And if a hard drive is a RAW drive, it may show 0 byte in size or your computer will asks you to format it, initialize it.
You may have encountered such a situation where your external device or a partition suddenly becomes RAW and you have no idea what's going on. In fact, there are several for this situation:
For mobile devices:
😭 Damaged mobile device - Damaged mobile device - Ejecting mobile devices without clicking "Eject" or "Secure Eject", also if the mobile device is read or write, shutdown or reboot may also damage the mobile device.
💽 Disk I/O errors - If the USB power supply to the external mobile device is unstable, disk I/O errors may occur. This indicates that the external hard drive is experiencing serious problems and is unable to perform file transfers. When Windows starts displaying I/O errors, all files and data stored on the external hard drive may be permanently lost.
💻 Disk bad sectors/sectors - Bad sectors in the file system or partition table can cause partitions to be unreadable
❌ Operation error - an error in the process of adjusting or merging partitions, etc.
🧿 Virus or unknown device access - a virus or malware that destroys some critical data on a partition. The use of unknown devices, hardware, etc. can cause data storage problems.

NTFS is a logging file system, which means that in addition to writing information to the disk, the file system keeps a log of all changes that have occurred. This feature makes the NTFS file system easier to recover in the event of an error (such as a system crash or power supply interruption) without losing any data, so the file system is used on most hard disk devices.

You can recover data by making a backup of the RAW partition or by using hard drive recovery software hard drive.
1.What should I do if the disk shows RAW and cannot be opened?
A disk showing RAW indicates that the disk is corrupted, in many cases the disk's file system is damaged. At this point, the operating system may indicate that it is not formatted. If the data on the disk is relatively important, then do not format it. The first thing you should do is data recovery. With the help of data recovery software, you can extract the data without any problem. After that, the disk can be formatted.

SD card won't open prompting formatting may be caused by abnormal plugging and unplugging, the partition on SD card is corrupted and the data is inaccessible. In this case, do not rush to format the SD card. Because SD cards mostly use FAT32 or exFAT file system, formatting will damage the original data more. When using data recovery software to search for files, try to use deep scan to find as much data as you want.
