RAW Drive: What It Means, How to Fix It, and How to Recover Your Files

A RAW drive is one Windows cannot recognize — the file system (NTFS, FAT32, exFAT) is missing or severely corrupted. Windows Disk Management shows "RAW" under the File System column. The drive is detected, but its contents are inaccessible through normal means.

Part 1. Why Drives Go RAW

⚠️ Important: Do not format the drive when Windows prompts "You need to format the disk before you can use it." Your files are in the sectors — they're just invisible because the file system directory is broken. Formatting makes recovery harder.

Part 2. Fix the RAW Drive With TestDisk

TestDisk is the best free tool for restoring RAW drives:

1. Run TestDisk as Administrator
2. Select the RAW drive
3. Choose partition type: Intel (for most drives), EFI GPT (for modern Windows drives)
4. Analyse → Quick Search → look for the original partition
5. If found, press Write to restore the partition table
6. Reboot — the drive should return to its original file system

If Quick Search finds no partition, run Deeper Search (slower, more thorough).

💡 Tip: If TestDisk finds your partition as NTFS or FAT32 but the drive still shows RAW after writing the partition table, run CHKDSK after rebooting: chkdsk E: /f /r. The partition table repair may have restored access, but the file system still has errors that CHKDSK can fix.

Part 3. Recover Files From the RAW Drive Before Fixing

Even before TestDisk repairs the partition, data recovery software can scan the raw sectors and extract files:

🗣️ r/datarecovery guidance: "On a RAW drive, try TestDisk first — if it finds your partition and restores it, you get everything back instantly with original names and folder structure. If it can't find the partition, then use recovery software for a raw sector scan."

Part 4. Check If the Drive Uses an Incompatible File System

If the drive was formatted on a Mac (APFS/HFS+) or Linux (EXT), Windows shows it as RAW because it can't read those file systems:

• HFS+ on Windows: Install HFSExplorer to read without formatting
• APFS on Windows: Install APFS for Windows by Paragon
• EXT on Windows: Install DiskInternals Linux Reader

🗣️ r/techsupport user: "My external drive showed as RAW after I borrowed it to a friend with a Mac. Installed HFSExplorer and could read all my files without any formatting. The drive was HFS+ formatted on his Mac."

Part 5. Recover Files From a RAW Drive With Ritridata

Ritridata scans RAW drives directly at the sector level — no working file system required. Supports NTFS, FAT32, exFAT, HFS+, and APFS drives showing as RAW on both Windows and Mac.

Step 1 — Select the RAW drive from the drive list

Step 2 — Run a deep scan — reads sectors directly, bypasses missing file system

Step 3 — Preview and recover files to a healthy drive

FAQ

What is a RAW drive in Windows? A drive showing as RAW in Disk Management has no file system that Windows can recognize. It is detected by hardware but cannot be browsed in File Explorer. The files are physically on the drive — only the directory structure is missing or corrupted.

Can CHKDSK fix a RAW drive? No — CHKDSK requires a readable file system. It returns "The type of the file system is RAW. CHKDSK is not available for RAW drives." Use TestDisk to repair the partition table first, then run CHKDSK after the file system is restored.

Is it safe to format a RAW drive? Formatting restores usability but makes file recovery harder. Only format after recovering all important files — or if you confirm the drive has never contained data you need.

Can I recover files from a RAW drive without formatting? Yes — data recovery software reads raw sectors and reconstructs files without needing a formatted file system. This is the recommended approach for RAW drives with important data.
