Method 1. Fix RAW External Hard Drive Without Formatting

If the drive shows RAW but still has a drive letter, you can try to fix the RAW hard drive without formatting it using CMD. With CHKDSK, you have a chance to fix your RAW hard drive without formatting it. Some people might say that CHKDSK is not available for RAW drives, but that's not true. If your external hard drive appears with a drive letter, you can use CMD to try and fix it. If your external hard drive is shown as RAW without a drive letter, follow Method 2 instead.

Running chkdsk can hopefully fix the RAW drive issue, however, it can also result in total data loss. So, perform data recovery in advance, and then continue with the CMD method.

Step 1. Connect your RAW external hard drive to your computer.

Step 2. Click the "search" icon in the taskbar and type cmd. Then, right-click "Command Prompt" and choose "Run as administrator".

Step 3. Enter chkdsk G: /f and hit Enter to fix your RAW external hard drive. (G is the drive letter of your RAW drive.)

After the repair process, you can open Disk Management to check if your hard drive is repaired. If CHKDSK is not working, don't worry. You can fix your RAW external hard drive using the method below. You can also check the following passage to fix the CHKDSK issues:

Method 2. RAW Drive Fix: Format RAW External Hard Drive to NTFS Without Losing Data

A straightforward way to do this is to first recover data from the RAW external hard drive first and then format it to NTFS or other file systems you like. As mentioned above, RAW means your external hard drive is not formatted. Thus, the direct way to fix it is to format the RAW drive to NTFS, FAT32, or other file systems available. However, as we all know, formatting inevitably causes data loss on your storage device. To avoid data loss, you can use the 100% secure EaseUS Data Recovery Wizard to recover your files before or after the formatting process.
