My external hard drive suddenly shows up as RAW and Windows keeps asking me to format it before I can open it. It has important photos, work files, and personal documents that I haven’t fully backed up yet. I need help figuring out the safest way to recover data from a RAW hard drive without formatting it first or making things worse.
I ran into this more than once, and the first time I saw a drive flip to RAW, I assumed it was finished. Turned out I was wrong. RAW does not always mean the disk is dead. Most of the time, Windows is failing to read the file system, so the files are still sitting there, but the OS has no clean way to map them.
I’ve seen a few different triggers for it. Sudden shutdowns. Pulling an external drive too fast. Corruption in NTFS or exFAT. Bad sectors starting to spread. Malware. A damaged partition table. Sometimes the disk itself is starting to fail and this is one of the first ugly signs.
What I’d check first is simple: is this a file system problem, or is the hardware going bad?
If the drive shows up in Disk Management, reports the right size, stays online, and isn’t making clicking or scraping noise, I’d treat it like a logical issue first and try recovery on my own.
If it drops connection over and over, shows the wrong capacity, disappears mid-scan, makes weird sounds, or SMART is full of errors, I’d stop messing with it. At that point, more scans mean more stress on a bad disk. If your files matter, I’d skip experiments and go to a recovery lab.
For a healthy-looking drive, I would not start by “repairing” RAW. I’d pull the files off first.
The first tool I’d try is Disk Drill. I had better luck with it on RAW volumes than with a lot of built-in Windows stuff. It checks for leftover file system records first, which sometimes are still there even when Windows gives up. If those records are too damaged, it falls back to file signature scanning and searches the disk by file type instead.
My usual steps:
- Install Disk Drill to a different drive, never onto the RAW one.
- Pick the RAW disk or partition.
- Hit Search for Lost Data. On an external drive, use Universal Scan if it asks. The one case where I’d pick something else is camera or drone footage with fragmented video files. Then Advanced Camera Recovery tends to do better.
- Let the scan finish, even if it looks slow.
- Preview what it found.
- Recover everything you need to another device.
I would only touch repairs after opening a sample of the recovered files and making sure they’re good.
If the partition used NTFS before it turned RAW, CHKDSK sometimes repairs boot sector or file system damage. I still would not run it first. It writes changes to the disk, and I’ve seen people make recovery harder by doing that too early. If CHKDSK does nothing, or if the file system wasn’t NTFS in the first place, I’d switch to TestDisk.
If neither one restores the partition, I wouldn’t keep forcing it. I’d recreate the partition in Disk Management, do a quick format, and copy the recovered data back onto it.

Yes. Recover first. Format later.
If Windows shows RAW, do not click Format. Do not save new files to it. Do not run repair tools first if the data matters. I agree with @mikeappsreviewer on the main point, but I’m less eager to try CHKDSK at all. On a damaged file system, it sometimes “fixes” things by removing the path to your files. That helps Windows, not you.
What I’d do:
-
Check the drive in Disk Management.
If the size looks correct, that’s a decent sign. -
Check SMART health with something like CrystalDiskInfo.
If health is bad, or the drive disconnects, clone it first with a sector-by-sector tool, then scan the clone. -
Recover files to a different disk.
Disk Drill is a solid pick for RAW partitions because it finds both old file system records and file signatures. Save recovered stuff somewhere else, not back to the RAW drive. -
Only after your files are safe, wipe and reformat the drive.
If you want a simple guide on how to recover files from a RAW or corrupted hard drive without formatting first, this video helps: watch this RAW drive data recovery walkthrough
Small thing people miss, try a differnt USB cable and port first. I’ve seen bad enclosures fake a RAW issue. If the drive starts clicking, stop messing with it. Thats lab territory.
Yes, you can often recover files from a RAW hard drive without formatting first. The big thing is: don’t let Windows “help” you by formatting it yet.
I mostly agree with @mikeappsreviewer and @reveurdenuit, but I’m gonna push one extra point: before running any deep scan, try the easiest non-writing checks first. Different USB port, different cable, and if it’s an external with a flaky enclosure, try another enclosure or adapter. I’ve seen a perfectly fine drive look RAW just because the USB bridge was having a meltdown. Stupid, but real.
What I would not do:
- Don’t format
- Don’t copy new stuff onto it
- Don’t run random “fix RAW drive” tools from search results
- Don’t keep power-cycling it 40 times if it keeps disconnecting
One thing I slightly disagree on: people jump to repair utilities too fast. Even “safe” repair attempts can change metadata, and that can make clean file recovery harder later. If the files matter, extraction first, repairs second.
My order would be:
- Check if the drive shows correct capacity in Disk Management.
- Check SMART if possible.
- If unstable, clone the drive first.
- If stable, scan it with something built for RAW partition recovery like Disk Drill.
- Recover files to another drive, never back to the RAW one.
- Only after verifying your photos/docs open properly, reformat the original disk.
Disk Drill is actually decent here because RAW usually means damaged file system metadata, not insta-death. A good scanner can still pull directory structure or at least recover by signatures. That’s usually way better than panicking and clicking Format becuase Windows nags you.
Also, if you want a simple visual walkthrough, this is a pretty easy RAW hard drive recovery guide without formatting first.
If the drive is clicking, buzzing, vanishing mid-scan, or showing the wrong size, stop. That’s the point where DIY can turn “recoverable” into “oops”.
Yes, usually you can recover from a RAW drive without formatting first.
Small disagreement with @reveurdenuit, @jeff, and @mikeappsreviewer on one point: I would also check the drive on another computer before doing anything heavy. Sometimes Windows on one machine misreads the volume, while another system or even a Linux live USB can still see files normally. That is a low-risk test and can save a lot of hassle.
What matters most:
- Do not format
- Do not run defrag or cleanup tools
- Do not recover files back onto the same drive
My practical take:
- If the drive sounds normal and shows the correct size, chances are this is file system damage, not total failure.
- If it is slow, freezing Explorer, or disconnecting, assume the drive may be degrading and keep use to a minimum.
About Disk Drill specifically:
Pros:
- Good at scanning RAW partitions
- Can often recover both folder structure and file types
- Preview helps verify photos/docs before recovery
- Easier for non-tech users than a lot of recovery tools
Cons:
- Deep scans can take a long time on large drives
- Best features are not really ‘free recovery’ for big jobs
- Signature-based recovery may lose original filenames/folders if metadata is badly damaged
So yes, Disk Drill is a reasonable option here, especially if you want something less fiddly than manual tools.
My order would be:
- Test another cable, port, and computer.
- Check whether the drive is detected with correct capacity.
- If stable, scan and recover to a different disk.
- Verify recovered files actually open.
- Then wipe and reformat the RAW drive only after data is safe.
If the drive clicks or disappears during reads, skip DIY. That is where recovery labs start making more sense.
