There is an NTFS partition on my external disk where I store many photos and documents, the partition becomes inaccessible after I unplugged the USB device incorrectly from my computer. When I try to open it, I received the error message: "The drive is not formatted. Do you want to format it now?" After that, I tried to repair the partition file system using CHKDSK, but I got a error message saying: "The type of the file system is RAW. CHKDSK is not available for RAW drives.". Is there any way to help me fix "CHKDSK is not available for RAW drives." error and get my lost data back?
After a partition becomes a RAW partition, if we try to open the RAW partition in Windows Explorer, we will get the "The drive is not formatted. Do you want to format it now?" error prompt.
As we all know, we may lose all of the files on this partition if we choose to format this partition as prompted, so many users who are familiar with Windows will try to use CHKDSK to fix the error. Unfortunately, if you try to repair a RAW partition, CHKDSK will prompt you "The type of the file system is RAW. CHKDSK is not available for RAW drives.".
RAW file system occurs when file system goes wrong, and it can't be recognized by Windows, so we will not be able to access the files on this drive. If the file system is severely damaged or corrupted, we will not be able to use CHKDSK to fix/repair this partition.
There are many reasons for the drive to become RAW drive, such as corrupted or damaged file system, corrupt partition table or MBR, unsafe ejection drive, sudden power failure, unexpected shutdown, bad sectors, virus infection, etc.
As CHKDSK can't repair RAW drive, we have to reformat the partition to reuse the space. Before that, we have to recover as much of the lost files as possible from the RAW drive, so it is important for us to find a professional RAW data recovery software.
