Correcting the RAW File System on an SD Card

Sometimes the file system of our drives may be damaged for some reason and become unreadable in the Windows operating system and is represented in RAW format. Windows will not be able to open the contents of the device and will prompt you to format the SD card. Otherwise, if you do not confirm this offer, the system will notify you of an error every time you try to view a file.

Many users may panic if they encounter such a problem, but do not get upset ahead of time. Below you will find a simple instruction, following which, you will quickly recover not only your drive, but all the valuable data. These methods can be useful for both the SD card, and for any other drive.

Using CMD to fix the RAW file system without formatting

The classic way to restore a drive in case of any logical damage, including RAW file system format, is to fix a problem with the chkdsk utility using the cmd command line. Being a free Windows tool for repairing disk partitions, chkdsk becomes the first way to solve a problem with the failed device.

1. Open a command prompt:
   Start > Run > cmd.exe ( you can call window using Win + R key combination)
   
   
2. In the command prompt, type
   chkdsk /F G:
   (Assuming your drive is labeled with G letter, respectively, type chkdsk /F G:)
   
   

Upon completion of the two steps above, CMD will correct the error on your SD-card, and with some luck, retaining all the available data on it. Unfortunately, periodically during the execution of the first recovery method, you may receive an error message “RAW file system” or “CHKDSK is not available for RAW drives”. This article describes the way of fixing such a mistake.

If everything didn’t go as smoothly as you wanted, try a different method using the Starus Partition Recovery software.
