How to fix 'The type of the file system is RAW, chkdsk is not available for RAW drives'?
Sometimes the drive gets corrupted and you cannot access the files stored on it. The Windows CHKDSK command is the first solution most users turn to, but in some cases, it returns an error saying The type of the file system is RAW. Chkdsk is not available for RAW drives.
Anyway, what is wrong with the drive when chkdsk reports RAW error?
There are so many important data stored on it, and chkdsk tool will complain that it is unable to perform a RAW file system recovery; how to fix RAW drive?
What is the CHKDSK command?
Chkdsk (short for check disk) scans a drive or other storage volume to verify its integrity. If it finds logical errors in the file system, it can correct them.
To run a scan with CHKDSK, you need to open the Windows Command Prompt. Clic on the Start menu and type "CMD" in the search field. Right-click on CMD.EXE and select Run as Administrator.
This opens the Command Prompt window with a command line for running various diagnostic tools. To run CHKDSK, enter the following command:
CHKDSK X: /f /r

If the drive that's reporting the CHKDSK is not available for RAW drives error is the computer's boot drive (C:), you won't be able to start the computer to run iBoysoft Data Recovery.

Fix 5: Fix RAW drive by reformatting
As we mentioned already, you can fix a RAW drive by converting it to either the NTFS or the FAT32 file system. The important factor here is whether or not you need to save any data on the drive.
If there's nothing on the drive that you need to recover, you can format it with the following steps.
Step 1: Open a File Explorer window, click on This PC (or My Computer), and right-click on the RAW drive.
Step 2: Click on Format in the menu that appears.
Step 3: Select the file system (NTFS or FAT32) and adjust the other settings as needed (allocation unit size, volume label, and format options).
Step 4: Click Start to reformat the RAW drive to whichever file system you selected.
Fix 6: Fix RAW drive using CMD
If you can't repair the RAW drive using the above two methods, it means you'll need to convert the drive from RAW to either the NTFS or FAT32 file system. This means you need to format the drive.
If there are no files on the drive that you need to save or recover, you can go ahead and format it. But if the drive does hold important data, you'll lose it if you format from RAW to either NFTS or FAT32. In that case, you need to recover the data first with iBoysoft Data Recovery software.
If you prefer to work from the command prompt, you can convert the RAW drive to either NTFS or FAT32 using the diskpart command. Just keep in mind that the same warning applies here - you'll lose any information on the drive if you don't recover it first.
Step 1: Click on the Start menu and type CMD in the search box.
Step 2: Right-click CMD.EXE and select Run as Administrator.
Step 3: Type DISKPART and hit Enter to open the Diskpart utility.
Step 4: Type LIST VOLUME and press Enter to see the list of drives.
Step 5: Type SELECT VOLUME n (where "n" is the drive number) and press Enter to select the drive you want to format.
Step 6: Type FORMAT FS=NTFS QUICK and press Enter to format the drive. Replace NTFS with FAT32 if you want to use that file system.
If Windows and diskpart command are unable to format the RAW drive, the RAW drive should have hardware issue, please try the 3rd-party professional format software or low-level format tool.
Fix 7: Using a data recovery service
If none of the previous solutions work, you'll need to send the drive to a data recovery service to have your files professionally recovered.
These services will disassemble the drive and move the storage platters into a new, working drive to read the information. This is a time-consuming and labor-intensive process so expect to pay quite a bit for it.
When encountering the following RAW drive scenarios, it means the RAW storage device has a hardwae issue, send it to a local specialist for data recovery assistance.
1. The capacity of the RAW drive is 0 bytes.
2. The RAW drive doesn't have correct capacity:
3. Drive is not accessible. Data error (Cyclic redundancy check) when accessing RAW drive in My Computer or Windows explorer:
4. The lost data is not found by iBoysoft Data Recovery software:
