How to recover lost data from a RAW SD card drive?

Updated on July 4, 2023 by Admin to RAW Data Recovery

I have a 16G SD card for storing photos, and I haven't used it for a while. Yesterday I used it to store other photos, and I found I couldn't access it anymore. When I try to open it, it prompts "You need to format the disk in drive *: before you can use it. Do you want to format it?". When I right clicked it to see the properties, the file system was RAW and the used space showed 0 bytes. I can't format it because these photos contain a lot of my good memories. What am I supposed to do for recovering lost files from the RAW SD card drive?

RAW SD card drive

If your SD card becomes a raw device, you will not be able to access the files stored on the device. If you check the properties of the SD Card drive in Windows Explorer, the usage space and free space are shown as 0 bytes, and the file system type is is shown as RAW instead of FAT, exFAT and NTFS.

Obviously, we can't format the SD card according to the prompts, because formatting can cause us to lose data permanently, we need to recover data from the SD Card drive before formatting it.
