Formatting an unreadable RAW hard disk or flash disk involves converting the RAW format into a recognizable file system such as NTFS, FAT32, or exFAT. When a drive turns RAW, it means that its file system is either missing or corrupted, rendering the disk unreadable by the operating system. The formatting process will erase all existing data, but it is necessary to make the drive usable again. Before proceeding, it’s crucial to ensure that any important data on the RAW disk is recovered using data recovery tools. Once the data is recovered (if needed), the drive can be formatted through disk management tools available on most operating systems, such as Disk Management in Windows or Disk Utility in macOS, or using third-party software designed to handle RAW drives.
Identifying the RAW Hard Disk or Flash Disk
The first step in formatting an unreadable RAW hard disk or flash disk is to confirm that the drive is indeed in RAW format. When connected to a computer, a RAW drive may not appear in "My Computer" or "This PC," but it should still be visible in the Disk Management tool in Windows. By opening Disk Management, you can check the status of the disk. If the drive is labeled as RAW, this indicates that the file system is corrupted or missing, and it cannot be accessed normally. Once the RAW status is confirmed, the next step is to prepare the drive for formatting.
Data Recovery Before Formatting
Before proceeding with formatting a RAW hard disk or flash disk, it is essential to attempt data recovery if the drive contains important files. Formatting the drive will erase all data, so if you want to retrieve your files, use a data recovery tool designed for RAW drives. Applications like EaseUS Data Recovery, Recuva, or Disk Drill can scan the RAW disk and recover readable files before you format the drive. It is important to act quickly, as continuous attempts to access the drive may further corrupt the data. Once recovery is complete, or if the data is not needed, you can proceed with formatting.
Formatting the RAW Hard Disk Using Windows Disk Management
In Windows, formatting a RAW hard disk or flash disk can be done easily through Disk Management. First, open the Disk Management tool by right-clicking on the Start menu and selecting "Disk Management." Locate the RAW disk, which will likely be marked as unallocated or RAW. Right-click on the disk and choose the option to format it. You will then be prompted to select a file system, such as NTFS or FAT32, depending on your needs. NTFS is ideal for internal drives, while FAT32 or exFAT may be more suitable for flash drives or external disks. After selecting the desired file system, follow the prompts to complete the formatting process.
Formatting a RAW Disk Using Command Prompt
For users who prefer a command-line approach, Command Prompt in Windows provides an alternative method for formatting a RAW hard disk or flash disk. Open Command Prompt as an administrator, then use the diskpart command to access the disk management utility. First, type diskpart, then list disk to view all connected drives. Identify the RAW disk by its size and use the select disk [number] command to choose the drive. After selecting the drive, type clean to erase the disk, then use the create partition primary command followed by format fs=ntfs quick or format fs=fat32 quick depending on the file system you want to use. This will quickly format the RAW drive into a usable format.
Using Third-Party Tools to Format RAW Drives
If the built-in tools in your operating system fail to format an unreadable RAW hard disk or flash disk, you may need to use third-party disk management software. Programs like MiniTool Partition Wizard, AOMEI Partition Assistant, or Paragon Hard Disk Manager can often handle complex formatting issues that the default tools cannot. These programs provide a user-friendly interface and additional features such as the ability to recover partitions or perform deep scans to fix file system errors. Simply download the software, install it, and follow the on-screen instructions to format the RAW disk into a usable format like NTFS, FAT32, or exFAT.
Fixing RAW Drives with CHKDSK Command
In some cases, you may be able to fix a RAW hard disk or flash disk without formatting by using the CHKDSK command. This command checks the file system and repairs logical file system errors, which can sometimes restore a RAW drive back to its original state. To use CHKDSK, open Command Prompt as an administrator and type chkdsk X: /f, replacing "X" with the drive letter of the RAW disk. This process may take some time, but it can potentially repair the disk and recover the file system without the need for formatting. However, CHKDSK is not always successful with severely corrupted drives, in which case formatting may still be necessary.
Formatting RAW Hard Disks Using macOS Disk Utility
If you’re using a Mac and need to format a RAW hard disk or flash disk, the Disk Utility tool in macOS provides a simple way to do this. Open Disk Utility by searching for it in Spotlight, then select the RAW disk from the list of drives. Click on the "Erase" button at the top of the window, which will prompt you to choose a file system. For internal drives, select APFS or Mac OS Extended, while for external drives or flash disks, you may prefer exFAT or MS-DOS (FAT) for broader compatibility with other operating systems. After selecting the file system, click "Erase" to format the drive.
Converting RAW Drives Without Data Loss Using Partition Tools
Some partition tools offer the option to convert a RAW hard disk back to NTFS or FAT32 without losing data. Tools like AOMEI Partition Assistant provide a "Partition Recovery" feature that can scan the RAW disk and attempt to restore the original file system without erasing the data. This is a useful option if the data on the disk is irreplaceable and you want to avoid the traditional formatting process. After recovering the partition, you may still need to repair file system errors, but this method can help you regain access to your files before taking more drastic actions like formatting.
Preventing RAW Format in the Future
Once you have successfully formatted your RAW hard disk or flash disk, it’s important to take steps to prevent the drive from becoming RAW again in the future. This includes safely ejecting external drives, avoiding sudden power losses during disk use, and regularly scanning for malware that could corrupt the file system. Keeping backups of important files will also minimize the risk of data loss if the drive turns RAW again. Additionally, periodically running disk check tools can help catch file system errors early, reducing the likelihood of corruption that can lead to the RAW format.
Recovering Data from a Formatted RAW Drive
After formatting a RAW hard disk or flash disk, it’s often assumed that the data is lost forever. However, in some cases, data recovery tools can retrieve files from a formatted drive, especially if the drive has not been extensively used since the formatting. Software like EaseUS Data Recovery or Recuva can scan the formatted disk and recover deleted files. This is possible because formatting a drive usually only removes the file system reference, not the actual data, until it is overwritten. If you accidentally format a RAW disk without recovering data first, using these tools can offer a second chance to retrieve your files.
Reformatting RAW Drives for Different Operating Systems
When formatting a RAW hard disk or flash disk, it’s important to choose the right file system based on the operating system you’ll be using. For Windows-only use, NTFS is typically the best choice due to its support for large files and security features. However, if you need to use the drive on both Windows and macOS, it’s better to use exFAT, which is compatible with both systems. For Linux users, ext4 is the preferred file system. Choosing the correct file system ensures that your disk remains usable across different devices, reducing the chances of the disk becoming RAW due to incompatibility issues.
