Causes for RAW Partition on External Hard Drive
If your external hard drive is in RAW file system, you may want to learn the reasons. In general, the causes for this issue can be various in Windows 7/8/10.
- Virus infection: Computer viruses are widespread. If your hard drive turns RAW file system due to virus attack, it is possible that some parameters and information are changed/deleted.
- Partition table damage: this reason is very common. If partition table is damaged, the whole hard disk probably becomes RAW since Windows identifies partitions by the partition table.
- Bad sectors: perhaps there are some bad sectors on your external hard drive, and then RAW issue happens.
- Operating system reinstallation: it is likely that your disk is RAW after OS reinstallation. This is because the OS doesn’t update in time, then Windows doesn't support the file system.
- File system structural damage.
- Physically damage on hard drive.
- Unexpected power outage when using the computer.
- More other unknown factors.

How to Convert RAW to NTFS
Solution 1: Recover RAW Partition to NTFS
As you know, the partition table and volume boot sector are two places where you can store the partition information. Once partition table on your external hard drive gets corrupted or damaged, Windows will fail to read this disk for any reason, and it reports your disk as RAW. Although the data is still there, the RAW partition is unable to be accessed. In this case, data recovery should be the first thing in Windows 7/8/10.
Do you know how to recover data from RAW partition and then format RAW to NTFS? Fortunately, MiniTool Partition Wizard has an ability to recover RAW partition data. As a piece of third-party software, it is reliable and professional to manage your disk and partition. Moreover, this partition software is compatible with some operating systems including Windows Vista/XP/7/8/8.1/10.

This RAW to NTFS converter owns six editions, among them, the Professional Edition is highly worth recommending since "Partition Recovery" is a paid feature. Its Free Edition can only be used to scan lost partitions but not to recover partitions.
Step 1: Launch MiniTool Partition Wizard Professional Edition. Then, go to its main interface.
If RAW issue happens due to damaged partition table and boot sector, here you will find all partitions on your external hard drive have become unallocated space in Partition Wizard. (In Disk Management, partition shows "RAW".)

Right click on your external hard drive to select "Partition Recovery" feature in Windows 7/8/10. You can also select the target disk, and click "Partition Recovery" from "Check Disk" drop-down menu.
Step 2: Then it is time to choose a scanning range. From the following figure, you know MiniTool Partition Wizard provides three scanning range settings:
- Full Disk: This mode is suitable to scan the entire disk.
- Unallocated Space: It only scans the free space on your selected disk.
- Specified Range: It is useful to scan specified sectors.
Then click on "Next" button to continue.
Step 3: Then set scanning method for the specified scanning range. "Quick Scan" and "Full Scan" are two scanning methods. Between them, the former can restore lost/deleted partitions which are continuous and the latter is designed to scan each sector of the scanning range you have chosen.
Step 4: After finishing the scanning, all partitions on your external hard drive will be listed here and then please select the partitions you need.
Take the first partition as an example. When double clicking on this partition which is in RAW file system in Disk Management, and then all partition data will be displayed. Please check whether the files are your needs.
Step 5: After that, click "Finish" to go back to the main interface of MiniTool Partition Wizard. Here you can preview all RAW partitions will be converted to NTFS. Finally, hit "Apply" button to perform RAW partition recovery operation in Windows 7/8/10.

Solution 2: Format RAW Drive
If your external hard drive becomes RAW due to virus attack, improper operations, bad sectors or power outage, you can try to format this RAW partition to NTFS. Here maybe you ask: there are many files saved on your disk , but formatting will lead to data loss, so could the partition data be recovered firstly and then start to format? Of course. Here MiniTool Solution Ltd. also has a piece of professional data recovery software – MiniTool Power Data Recovery which is useful to recover data from RAW partition in Windows 7/8/10.
Before RAW data recovery, please stop doing any operation to your RAW drive on external hard drive, especially formatting. Otherwise, the chance of data recovery is slim.

After finishing the recovery, now formatting RAW drive can be done. Usually, In Disk Management, you probably right click on the RAW drive and select "Format" feature to convert RAW to NTFS on external hard drive in Windows 7/8/10. Sometimes you can do this successfully, however, sometimes an error message saying "The format did not complete successfully" appears.
Format in Windows Explorer

Convert RAW to NTFS by MiniTool Partition Wizard
In addition to the above three tools, you can also ask MiniTool Partition Wizard for help. This partition manager can do the conversion between NTFS and FAT32, but "convert is not available for RAW drives" issue is a common sense on external hard drive, SD card, USB drive and other media since RAW is a false file system, so you can only use this tool to format your RAW partition in Windows 7/8/10.
Step 1: In Disk Management, partition is in RAW file system. In the main interface of Partition Wizard, you will find the RAW drive shows "unformatted". Please click "Format Partition" feature from "Partition Management" menu.
Step 2: Select NTFS as the file system from the list. During the process, it is allowed to set partition label for the target partition.
Step 3: Click "Apply" button to make this change effective.

Solution 3: Check RAW File System
If your external hard drive becomes RAW, maybe you choose CHKDSK to find and fix file system errors. Usually when opening diskpart to start the check, "CHKDSK is not available for RAW drives" error appears.
But sometimes "CHKDSK X: /f" can be done successfully. Why? Sometimes in Disk Management, your partition shows RAW file system. But in fact, it is not recognized as RAW by diskpart due to some unknown reasons. So you can try this solution in Windows 7/8/10.
Run MiniTool Partition Wizard
If you also fail to convert RAW to NTFS on external HDD by CHKDSK, MiniTool Partition Wizard is also useful. When launching it to the main interface, perhaps your partition which shows RAW in Disk Management shows NTFS files system here. At this time, you can reboot your computer. If the partition is still normal in Partition Wizard, it is most likely the key file system information is corrupted. So please check and fix file system now.
Step 1: Right click on the target drive to select "Check File System" feature.
Step 2: Then in the pop-up window, there are two options for choice. Here select "Check & fix detected errors". And then click "Start" button to continue.
