My USB drive suddenly shows up as RAW instead of NTFS, and I can’t open any of my files. I need help figuring out the safest way to convert a RAW USB drive to NTFS without losing important data, or at least recover the files first before formatting.
I’d hold off on converting it to NTFS right away. When Windows shows a partition as RAW, what I usually read from that is simple: the system no longer understands the file system sitting on the drive. I’ve seen this happen after a bad unplug, a write job getting cut off, file system damage, weak sectors, malware, or a drive starting to go bad.
A RAW label does not always mean your files are gone. A lot of the time, the data is still sitting there, and the worst move is to start “fixing” things before you pull your files off.
First thing I’d check
Open Disk Management and look at the drive there. What I care about first is whether the size still looks correct. If the capacity shows up properly, recovery still has a fair shot, even if Windows marks it RAW.
If I saw any of this, I’d stop touching the drive:
- it disconnects on its own
- it shows the wrong capacity
- it makes odd clicking or repeated spin-up noises
When that starts happening, I usually assume hardware trouble until proven otherwise.
How I’d pull the files off
I’d use Disk Drill first because it’s easier than some of the older recovery tools and it stacks multiple scan methods into one pass. For a RAW partition, that saves time and cuts down on guesswork.
This is the order I’d follow:
- Install Disk Drill on a different disk. Don’t put it on the RAW drive.
- Open it and pick the RAW partition, or the full physical disk if needed.
- Hit Search for lost data and leave it alone until the scan ends. RAW volumes often scan slow. I wouldn’t stop halfway unless the drive starts acting worse.
- Go through the results with file-type filters or the search tool. If folder view is available, check it. I’ve had better luck there because you get a sense of whether the old directory tree survived.
- Preview your important stuff first, photos, docs, videos, whatever matters. If the preview opens cleanly, recovery odds are better.
- Select the files you want back.
- Save the recovered data to another drive, never back onto the RAW partition.
One thing I learned the hard way, if the drive starts crawling or drops offline during scanning, stop. Make a full byte-level image first. Reading from the image is safer than hammering a weak drive over and over. I didnt used to bother with this step, and I regretted it.
After your files are safe
Only then would I try to repair the drive itself. The fix depends on what broke.
These are the usual options:
- Format it to NTFS if the file system is damaged and you no longer need anything left on it.
- Repair or rebuild the partition setup if the partition table got messed up.
- Assign a drive letter if Windows sees the partition but refuses to mount it properly.
- Run CHKDSK only after recovery is done. It changes the file system, so I would not treat it like a recovery tool.
- Update or reinstall storage controller drivers and USB drivers if this started after a Windows update or only happens on one PC.
- Replace the drive if SMART alerts, bad sectors, or repeated read failures keep showing up.
Once the drive seems normal again, test it before trusting it. I usually copy a few large files over, unplug it properly, reconnect it, and check whether the files still read fine. If the partition flips back to RAW again after a format, I’d stop trying to rescue the device itself. At that point, the storage hardware is often the problem, not the file system.
Don’t convert RAW to NTFS first. That is the part where people lose data.
I agree with @mikeappsreviewer on waiting before formatting, but I’m less sold on trying repair steps early. CHKDSK on a RAW USB has a bad habit of making recovery messier, not cleaner. If your files matter, treat repair as the last step.
What I’d do:
-
Try the USB on another PC and another USB port.
Sometimes Windows is the problem, not the stick. -
Check Disk Management.
If the size looks correct, your odds are better. If capacity is wrong, or the drive drops out, stop poking at it. -
Recover data first.
Use Disk Drill and scan the whole USB, not only the RAW volume. On damaged flash drives, scanning the device itself often finds more than the broken partition entry does. -
Save recovered files somewhere else.
Not back to the same USB. Thats how people turn a bad day into a worse one. -
After recovery, wipe and format.
Use Disk Management or diskpart:
diskpart
list disk
select disk X
clean
create partition primary
format fs=ntfs quick
assign
If format fails, the USB is often dying.
For people searching this later, the goal is simple: recover files from a RAW drive before formatting, then rebuild the USB only after your data is safe.
Also, this video is worth a look if you want a quick visual guide on recovering files from a RAW USB drive without formatting first.
Short version, recover first, format later. If the stick keeps turning RAW again, toss it. It’s done.
I’m gonna disagree slightly with @mikeappsreviewer and @yozora on one part: I would not rush straight from “recover files” to “clean + reformat” unless you’re already sure the USB itself is healthy. A RAW file system can be corruption, sure, but it can also be the first warning that the flash controller is going weird. Formatting may make it usable for a day, then it flakes out again.
What I’d do differently:
- Check the USB with a SMART/flash health tool if it’s detectable
- Look in Event Viewer for disk/ntfs/usbstor errors
- If the drive is important, make an image of it first, then recover from the image instead of stressing the stick
That part matters more than ppl think. Flash drives can die fast once they start acting up.
Also, if TestDisk can still see the old NTFS boot sector or backup boot sector, sometimes you can restore partition/file system access without a full format. That’s riskier than pure recovery, but less destructive than just nuking it. I’d only try that after imaging though.
If you just need the files off, Disk Drill is still a solid pick for a RAW USB because it’s simple and previews recoverable files well. After recovery, do a full format, not quick, if you want to test the media. If it errors, gets slow, or turns RAW again, toss it.
For extra reading, this roundup on top hard drive recovery and repair software for fixing corrupted drives is decent too.
Short version: recover or image first, diagnose second, format last. Not the other way arond.
