You may get the "The type of the file system is RAW. CHKDSK is not available for RAW drives." error when you attempt to use the CHKDSK command to check and repair disk errors, like file system errors and bad sectors.
Feel familiar with the error message shown in the image above? This message means you failed to run CHKDSK on your drive due to a problem with the file system of your device.
The RAW file system is a file system that your computer can't recognize. The following are the reasons your hard drive or storage device like a USB flash drive or memory card's file system goes RAW:
When your hard drive or storage medium becomes RAW, running CHKDSK will fail and you will get a message that says "The type of the file system is RAW. CHKDSK is not available for RAW drives." If you try to open the drive, you may get the notification "You need to format the disk in drive X before you can use it. Do you want to format it?" Also, you cannot open your drive and access files stored on the device.
When the file system of your drive or external storage device goes RAW, it becomes inaccessible and unusable. To make it ready for data storage again, you need to convert RAW to NTFS or other Windows-compatible file systems by formatting. When you format your drive, you can assign a new file system to it and thus make it usable. However, as you may know, formatting erases the existing files on the storage medium. Thus, the procedures to fix the error "the type of the file system is RAW" are:
You can directly format your hard drive if there is no data on it or you don't need the files stored on it.
Although you can't access the existing files on a RAW drive, a data recovery tool like Qiling Data Recovery Software can. Not only does this software help recover deleted data, formatted data, and lost partitions, but it also helps recover files from the drives that have gone RAW and have thus become inaccessible.
To recover data from your drive or storage device that reports RAW:
Step 1. Select file types

If the RAW partition lost its label, it will be recognized as "Lost Partition", just select the "Lost Partition" and click "Scan" to initiate an overall scan on the RAW drive.
Step 3. Preview found data from the scan result
After the scan is completed, all available files in the RAW hard drive will be displayed. View these files and find the files you want to recover. You can sort the scanned data by file format or search directly in the "Search files or folders" box.
Step 4. Recover data from RAW partition
Select all files and click "Recover" to get all the data back. Select another internal or external hard drive to save the recovered data and click "OK" to start RAW drive recovery.
