Before we start: The drive will become RAW if there are issues with the file system. You can fix the problem or format the drive to make the drive accessible again. If there are important files on the RAW drive, it's necessary to recover the files first. Donemax Data Recovery is a reliable recovery tool which can help you get back the important files.

Each file systems has it's own specific purposes, capabilities, and limitations. Two of the most common file systems for storage devices are ExFAT and FAT32. Somes, a drive or device may become RAW. This provents access to the stored data. Converting RAW drive to ExFAT or FAT32 can restore access and functionality to the device.

In this article, we will cover the concept of RAW file systems, why converting to ExFAT or FAT32 might be necessary. Also we provide a procedural guide on how to perform this conversion safely. Whether you are using Windows, macOS, this guide will explain how to accomplish the task with the tools available on each platform.

Convert RAW to ExFAT or FAT32 Without Losing Data

What is a RAW File System?

A RAW file system occurs when the system cannot recognize the format of the drive or partition. Various operating systems support and recognize NTFS, ExFAT and FAT32. However, RAW signifies an absence of any readable file system. This can happen because of several reasons:

  • Corruption of the File System: Damage or corruption can heppen because of improper ejection or power loss. This can make a partition unreadable and leave it in RAW format.
  • Formatting Errors: Imcomplete file system conversion or bad sectors will make system may fail to recognize the file system.
  • Virus or Malware Attack: Malicious software can corrupt partitions, rendering them RAW.
  • New Unformatted Drives: New drives may appear as RAW if you haven't formatted them with any recognized file system.

Symptoms of a RAW Drive:

  • The drive appears as RAW in Disk Management or similar tools.
  • You may receive error message like "The drive is not formatted, do you want to format it?" when accessing the drive.
  • The drive's space shows as 0 bytes or unallocated.
  • Files and data on the drive are inaccessible.

To make a RAW drive usable, you can convert or format it into a readable file system, such as ExFAT or FAT32.

Understanding ExFAT and FAT32

FAT32 (File Allocation Table):

FAT32 is an older file system that has been widely used on USB drives, SD cards, and other external storage media. The format is compatible with many other devices, such as game consoles, cameras, PCs, and more. However, it has several limitations:

  • File Size Limit: FAT32 can only support files up to 4 GB in size. If you try to transfer files larger than this, you will encounter errors.
  • Partition Size Limit: FAT32 can only support partitions up to 32 GB in size. On Windows, drives larger than this are often difficult to format directly as FAT32.

ExFAT (Extended File Allocation Table):

Microsoft released ExFAT in 2006 with the intention of bridging the FAT32 and NTFS gaps. The file system is for external storage devices and offers several benefits:

  • No File Size Limit: Unlike FAT32, ExFAT allows the transfer of files larger than 4 GB. This makes it ideal for storing HD videos, large documents, or other large files.
  • Partition Size: ExFAT supports large partitions, up to 16 EB (exabytes), far exceeding FAT32's capacity.
  • Compatibility: ExFAT works across different platforms, including Windows, macOS, and Linux (with appropriate drivers).

When converting from RAW, choosing between FAT32 and ExFAT depends on your specific needs. If you need broad compatibility for older devices, FAT32 may be the better choice. If you deal with larger files and modern devices, ExFAT is likely more appropriate.

Recover Lost Data from a RAW or Formatted Drive

Before converting your RAW drive to ExFAT or FAT32, it is important to restore any data if possible. In most cases, converting a RAW file system will erase existing data. Therefore, consider using data recovery software before proceeding.

Methods to Format A RAW Drive to FAT32 or ExFAT on Windows Computer

Method 1: Using Disk Management

  1. Open Disk Management: Right-click on the Start menu and select Disk Management. This utility displays all the drives connected to your system.
  2. Identify the RAW Drive: Locate the drive that appears as RAW. It will typically show unallocated or RAW in the status.

Erase a RAW Drive to ExFAT or FAT32 on Mac

If you're using a Mac, the process of converting RAW to ExFAT or FAT32 is straightforward using Disk Utility.

  1. Open Disk Utility: Navigate to Disk Utility from Utilities from Applications.
  2. Select the RAW Drive: Locate and select your RAW drive in the left sidebar.

  5. Name the Drive: Provide a name for the drive if desired.
  6. Erase: Click Erase to confirm the formatting process.

Once the process is complete, your RAW drive will become ExFAT or FAT32, depending on your selection.

When to Choose ExFAT or FAT32:

Selecting the appropriate file system depends on how you intend to use the drive.

  • FAT32 is ideal for small USB drives, SD cards, and other device. It works well for devices under 4 GB and it is wide compatible. FAT32 is a common format for gaming consoles, digital cameras, and older operating systems.
  • ExFAT should be chosen if you need to store large files over 4 GB, such as high-resolution videos or databases. It is better suited for modern devices, external hard drives, and cross-platform usage between Windows and macOS.

Data Recovery Before Formatting:

If the data on the RAW drive is important, you should attempt data recovery before converting the file system. There are several data recovery tools available that can help retrieve files from a RAW drive:

  • Recuva: A free Windows tool with a simple interface.
  • Donemax Data Recovery: Offers recovery for both Windows and macOS.
  • PhotoRec: An open-source option that works across different platforms.

These programs can scan RAW drives for recoverable data, giving you the chance to save important files before reformatting.

Conclusion

Converting a RAW drive to ExFAT or FAT32 is essential to restore access and usability. But it requires careful steps to avoid data loss. The process involves erasing the drive and formatting it with the desired file system.

While FAT32 is widely compatible with older devices, ExFAT offers better support for large files and modern systems. In either case, always ensure to back up or recover important data before proceeding with the conversion.
