Recovering from a RAW RAID Disk Format on Windows 11: Is It Possible?
Experiencing sudden system failures can be alarming, especially when valuable data is at stake. Recently, I encountered a challenging situation when my Windows 11 computer abruptly shut down, which also affected my external Thunderbolt RAID 5 storage enclosure. Following the unexpected shutdown, I found that the RAID disk was no longer accessible, presenting me with a frustrating error message: “disk structure corrupted or unreadable.” To complicate matters further, the disk had shifted from a recognizable RAID 5 – NTFS format to an unreadable RAID 5 – RAW format.
After navigating out of the Windows Recovery environment, I discovered that the affected disk was visible in both File Explorer and Disk Management, yet I was unable to access the data it contained. Regrettably, standard Windows tools such as CHKDSK yielded no results, as they cannot function on a disk formatted as RAW.
Given that my enclosure is an OWC ThunderBay, I reached out to OWC’s technical support for assistance. However, the support team was limited in their ability to assist with non-MacOS systems. They recommended exploring third-party recovery software tailored for Windows environments. A few prominent options, including EaseUS and Stellar, came highly recommended; however, I remain cautious about their efficacy in dealing with a RAW format disk.
I find myself seeking advice from the community: does anyone have experience with data recovery in such scenarios? Furthermore, I would appreciate any recommendations for reliable software or methods. An additional consideration I’m contemplating is whether formatting the disk back to NTFS first, followed by utilizing a RAID recovery tool, would be a viable approach—would this lead to successful data recovery, or might it exacerbate the situation?
If you’ve faced similar challenges or have insights to share, I welcome your thoughts and suggestions. Recovery may seem daunting in this situation, but with the right knowledge and tools, hope remains.

Recovering data from a RAID disk that has transitioned to RAW format can be challenging but not impossible. Before attempting any writes or formatting, it is highly recommended to use specialized data recovery software designed for RAID and RAW disks to prevent further data loss. Tools like EaseUS Data Recovery Wizard, Stellar Data Recovery, or R-Studio support RAID configurations and RAW recovery options and have proven effective in similar scenarios.
It’s important to avoid formatting the disk immediately, as this can overwrite existing data and reduce recovery chances. Instead, consider creating a disk image or clone of the RAW volume using these tools to minimize risk during recovery attempts. After safely cloning, you can try to repair the RAID structure or recover files from the image.
Regarding the idea of formatting the disk back to NTFS prior to data recovery: generally, formatting a RAW partition to NTFS can make data recovery more straightforward if the data was not overwritten; however, if the disk is severely corrupted, this step might complicate recovery. It is often better to attempt data recovery on the RAW disk directly or on a clone thereof.
Finally, if you’re unfamiliar with RAID recovery procedures, consulting with a professional data recovery service might be the safest route, especially for critical or sensitive data. They have specialized tools to diagnose and recover RAID arrays in complex scenarios.
In summary, avoid quick formats, use reputable RAID-aware recovery software on a clone, and consider professional help
