Overview on "Convert is not available for RAW Drives" issue

"Hi everyone! I was trying to repaired a 500GB hard drive which shows RAW in Disk Management. It says I need to format it before I can use it every time I try to open it. I googled solutions with no luck. I've tried chkdsk /f which is said to repair corrupted drive. However, it did not work on my hard drive, for chkdsk is not available for RAW drive! This hard drive is used as an external hard drive to keep my backups of pictures, files, etc. I really cannot afford to lose those files. So, could anyone help me to repair the drive, save my data and convert RAW to NTFS?"

A partition becomes inaccessible and the file system becomes RAW in Disk Management. Also, this partition might be shown as Unformatted. If you google the issue, you may find many guides that suggest chkdsk. Unfortunately, such kind of guide can neither solve the problem nor get files recovered. "The type of the file system is RAW, chkdsk is not available for RAW drives" is one of the most common errors you may get when you try to run chkdsk on RAW drives. Many users attempt to retrieve data from RAW drive by way of chkdsk command, however, this command only works on very few situations. Many times, such operation is likely to cause further damage to the RAW drive. Therefore, if the RAW partition contains important files, you should try RAW drive recovery first before trying any other repairing approaches.


RAW file system

What is RAW file system?

RAW file system refers to a file system format that cannot be recognized by operating system. Actually, RAW drive is the result of a damaged or corrupted file system. Since there is not correct file system on the drive, it can never be accessed by system. As to operating system, it needs to format RAW drive to proper file system before it can access it. Thus, you will receive error message when you try to open RAW partition.

Solution 1: RAW drive recovery

Since the RAW drive cannot be converted to normal file system via command lines, the only method to retrieve data is to perform RAW drive recovery. RAW drive recovery or RAW partition recovery is the process of retrieving files and folders from inaccessible partitions or volumes without modifying or damaging original data. The recovery process is read-only, thus, you can recuse your data safely and completely.

If this function can load your files, you can preview data and then save needed files to a different location to get them recovered. If this step still cannot find out your data, you'll have to search for lost files from the inaccessible drive. Then move to next step.
