My USB flash drive was working normally as NTFS, but now Windows shows it as RAW and I can’t open any files. I have important data on it and don’t want to make things worse by formatting it too soon. I need help with the safest first steps to recover files and figure out what caused the NTFS to RAW file system change.
Yeah, sort of, but not in the way people expect. You do not flip a RAW drive straight back into NTFS like a switch. Once Windows labels it RAW, it is saying the NTFS structure is gone or unreadable, so there is nothing clean left to convert. What I’d do is recover the data first, then rebuild the file system after.
If I had the USB stick on my desk right now, I’d go in this order.
1. Stop touching the drive
Seriously, leave it alone for a minute. Do not copy anything onto it. Do not click the Windows format prompt. Do not run CHKDSK. I’ve seen people do one of those three and make recovery worse. Windows writes changes, CHKDSK tries to “fix” stuff, and both can wreck file records you still needed.
2. See if Windows still shows the device
Open Disk Management and check whether the USB drive appears with about the right size. If the full capacity still shows up and the partition is marked RAW, I’d still have some hope. If it keeps dropping off, reconnecting, or showing random size info, I’d start worrying about the hardware instead of the file system.
3. Pull your files off first
I’d start with Disk Drill. It is one of the easier tools if you do not want to spend an hour guessing what every button means, and in my use it handles RAW partitions decently.
What I’d do:
- Install Disk Drill on your PC, not on the damaged USB drive.
- Plug in the USB drive.
- Select the USB device in Disk Drill and hit Search for Lost Data.
- Wait for the scan to finish. On some drives this takes a bit.
- Look through the results by folder or by file type.
- Preview the files before restoring them.
- Recover everything onto a different drive.
A useful detail here, the Windows version lets you recover up to 100 MB for free. Scanning and previewing are not capped, so you get a decent look at what is still there before spending money. Previews usually work for common file types like documents, PDFs, pictures, video files, archives, and a bunch of RAW photo formats. I like this part because you get proof your stuff is readable before you start restoring it.
If the results look thin, I would not stop there. Try UFS Explorer or DiskGenius too. Different recovery tools pick up different leftovers. I’ve had one tool miss a folder tree and another one pull it up on the same drive. Weird, but it happens.
4. Reformat the drive as NTFS after the files are safe
Only do this after your data is somewhere else.
- Open Disk Management.
- Right-click the RAW partition.
- Pick Format.
- Select NTFS.
- Keep Quick Format turned on.
- Finish the process.
If Windows refuses to format it, I’d delete the RAW partition, make a new partition in the unallocated space, then format the new one as NTFS.
I’ve run into this after unsafe removal, power cuts during file copies, and plain old file system corruption. Most of the time, if the USB hardware is still stable, the best path is boring but safe, recover first, format second. Trying to “repair” it before saving the files is where people get burned.

First step, check if the problem is logical or physical. I agree with @mikeappsreviewer on not formatting first, but I’d put one thing even earlier. Read the USB’s SMART or at least watch its behavior in Event Viewer and Disk Management. If it freezes File Explorer, disconnects, or throws I/O errors, stop scanning it over and over. That wears it out faster.
What I’d do:
- Plug it into a different USB port, then a different PC.
- See if the size shows correctly.
- If it acts unstable, make an image of the drive first with a tool like USB Image Tool or ddrescue.
- Run recovery from the image, not the stick.
If the drive stays stable, then use Disk Drill to scan and preview files before saving them elsewhere. That part matters. Previews tell you if the file data is intact, not only the names. For many people, Disk Drill is the fastest path becuase the interface is simple and it handles RAW partitions well.
One small disagreement with the usual advice. CHKDSK is not always evil, but on a RAW USB with needed files, I would not touch it yet. It writes changes. Save data first.
After recovery, full format the flash drive once, not quick format, if you want to test it. If Windows reports bad sectors or the format fails, toss the drive. USB sticks fail a lot, and they fail ugly.
If you want a simple walkthrough, this easy guide to USB RAW data recovery lays out the recovery process in a clean way. It’s short and easy to follow, not too techy.
First step? Figure out whether this is file system damage or a dying flash drive, because those are two very diff problems.
I mostly agree with @mikeappsreviewer and @andarilhonoturno about not formatting and not running CHKDSK right away, but I’d add this: check the USB in Device Manager and Event Viewer before doing a big scan. If Windows is logging disk, ntfs, or controller errors every time you plug it in, that points more toward hardware flaking out than just a busted NTFS header.
A couple things I’d do first:
- Try reading it on another PC
- Try a diff USB port, preferably direct on the motherboard
- Check if Disk Management shows the correct capacity
- Watch whether it disconnects/reconnects by itself
If it stays stable, then yeah, use Disk Drill and scan the USB for recoverable files. I like it here because you can preview stuff before restoring, which tells you if the data is actually there and not just ghost filenames. That’s more useful than people think.
One small disagreement with the “full format after” advice: I would not trust a flash drive that randomly went RAW with important data on it. Even if you get it back to NTFS, I’d only reuse it for throwaway files, if at all. USB sticks are cheap, data isn’t.
If you want a simple visual walkthrough for how to recover files from a RAW USB drive, that’s probly easier than guessing through menus.
