Sometimes, when you plugged in an external hard drive, USB flash drive, SD card or some other storage devices into your Windows computer, Windows prompts "You need to format the disk in drive G: before you can use it. Do you want to format it?"
You might click Cancel to refuse to format the disk or card if there are some important data files. Then Windows will prompts "Drive G:\ is not accessible. The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted." This is how usually "The volume does not contain a recognized file system" error occurs in Windows 10/8/7.
To fix "The volume does not contain a recognized file system" error in Windows 10/8/7 without losing data, you should first figure out why this error happens. As we know, the possible reason is RAW file system which is not really a type of file system but presents a problem of your drive. It typically occurs when the file system type information is missing or inconsistent between several system tables. Such an issue often happens if you have ever forcibly unplugged your external hard drive from the computer without "Safely removing" them first.
After figuring out what result in "The volume does not contain a recognized file system" error, fixing it without data loss becomes quite easy. All you need to do at this point is to find a raw drive recovery software to get back the files, then format the device and copy the recovered data back to the device. Offering powerful and easy RAW recovery solution, EaseUS file recovery software allows you to recover your data from RAW drive before formatting or changing RAW to NTFS/FAT32 file system. It is the best way to solve "Drive is not accessible. The volume does not contain a recognized file system" issue in Windows 10/8/7/Vista/XP and Windows Server 2012/2008/2003.
Step 1. Select the disk where you lost your data and click "Scan" button.
Step 2. The software will start a quick scan first. After the quick scan completes, a deep scan will automatically launch in order to find more files.
Step 3. After scan, you can preview all the listed recoverable document and image files one by one and select out those you want. Then, click "Recover" button to get them back once. Here you should save all the recovered files on a different drive or memory card in case of data recovery failure.
