A number of times users see a prompt, asking to format the drive in order to open it. Most of the computer users are aware of this issue. A number of times such message appears for RAW partitioned drives. Most users face this issue while trying to access the drive. It is necessary to convert RAW to NTFS file system in order to access the drive.
The popup asks to format your drive to open or gives you a way back to the previous window. This is among some of the most annoying issues on the computer. As mentioned earlier, you can gain access to the drive only after you format it. But formatting results in deletion of all the important data stored in the drive. It can be a pain even if you know how data is recovered from hard disk that turned RAW on Windows 10, Windows 8, 8.1, Windows 7, Vista, XP, Windows Server 2003 and 2008, and on all versions of macOS including High Sierra, Sierra, El Capitan, Yosemite, Mountain Lion, etc.
The format disk window will show no space at all in your disk. You will see 0 bytes free and used space on your disk. But the most important issue to address would be the safety of your important data. Here is how you can convert RAW to NTFS without data loss.
If you run the CHKDSK command, you might counter an error from the disk. The message states ‘The type of file system is RAW, CHKDSK is not available for RAW drives’. This indicates that the drive has a RAW file system and needs to be formatted to get access.
However, it depends upon the operating system and versions about the file system recognition. In such cases, either the OS shows the drive as without partition or a RAW partition.
Convert RAW File System to NTFS
The situation with the RAW file system is due to a number of issues from corruption to hardware failure. Sometimes it appears due to IO errors and compatibility issues. When such situation arises, the system finds disk as unreadable and denies access to them. The amount of recovery depends upon the level of corruption and in grave situations, you can’t recover data. However, most of the time, corruption affects a small sector of the drive and all the data can be successfully recovered.
