My external hard drive was working fine, but now Windows shows it as RAW and says I need to format it before I can use it. It has important photos, work files, and personal documents that I haven’t backed up yet. I’m looking for the safest way to recover files from a RAW hard drive without making things worse or losing data.
I ran into this a few times, and the first time I saw a drive flip to RAW, I figured it was done for. Turned out RAW does not always mean the disk is dead. It usually means Windows stopped recognizing the file system, so the data is still sitting there, but the OS has no clean way to read it.
A bunch of things lead to this. I’ve seen it after a power cut, after pulling an external drive too fast, after file system damage, bad sectors, malware, partition table issues, and on drives starting to fail. A normal NTFS or exFAT volume ends up showing as RAW, which looks worse than it is.
What I’d check first is whether you’re dealing with file system damage or physical drive trouble.
If the drive shows up normally in Disk Management, reports the right size, stays connected, and isn’t making clicking or grinding sounds, I’d start with home recovery steps.
If it drops connection over and over, shows up inconsistently, makes ugly noises, or SMART throws a pile of errors, I’d stop there. Those signs usually point to hardware damage. Every extra scan adds more stress. If your files matter, I’d skip experiments and go straight to a recovery lab.
If the hardware looks stable, I would focus on getting the files off first, not repairing the RAW volume.
What worked best for me was Disk Drill. On RAW volumes, it first tries to find traces of the old file system. Sometimes Windows loses the map, but enough metadata is still there for recovery software to piece things back together. If that info is too damaged, it falls back to signature scanning and looks for known file types directly across the disk surface.
The steps are simple enough:
- Install Disk Drill on a different drive.
- Pick the RAW drive or RAW partition.
- Click Search for Lost Data. On an external drive, use Universal Scan if it asks. If you’re trying to recover fragmented video from a camera or drone, use Advanced Camera Recovery instead.
- Let the scan finish.
- Preview what it finds.
- Restore the files to another disk.
I would not try to repair the partition until I had checked a sample of the recovered files and confirmed they open.
After that, if the partition used NTFS before, CHKDSK sometimes fixes boot sector damage or file system corruption. I still would not run it before recovery, because it writes changes to the volume. If CHKDSK fails, or the file system was not NTFS, I’d move to TestDisk. If neither one brings the partition back, I’d recreate it in Disk Management with a quick format, then copy the recovered files back onto it.

Yes, RAW does not mean your files are gone. It means Windows lost access to the file system.
First thing, do not format it. Do not copy new stuff to it. Do not run repair tools yet.
I agree with @mikeappsreviewer on one big point, recover first. I disagree a bit on CHKDSK as a next move for most people. On a drive with family photos and work docs, I would leave repair attempts for later. CHKDSK has a habit of ‘fixing’ things by changing the file system, and sometimes your folder structure takes the hit.
What I would do:
- Try a differrent USB cable and port.
- Check the drive on another PC.
- Look in Disk Management.
- If the size looks correct, make a byte-for-byte image first if you have room. Use HDD Raw Copy Tool or ddrescue.
- Scan the image, not the original drive, with recovery software.
This is the safer route. If the disk is starting to fail, imaging first saves you from repeat reads. Labs do this for a reason.
For software, Disk Drill is a solid pick for RAW hard drive data recovery. It tends to pull photos, docs, and office files well, even when Windows shows the partition as RAW. If your goal is to recover files from a RAW hard drive without formatting, start there after imaging.
If you want a plain explainer, this video is decent for how to recover files from a corrupted hard drive.
If the drive clicks, disappears, or reads at 0 bytes, stop messing with it. That points more toward hardware than file system damage. At taht point, a recovery shop is the safer bet.
Yes, you can often recover files from a RAW hard drive. RAW usually means the file system got scrambled, not that every file vanished into the void.
I mostly agree with @mikeappsreviewer and @sognonotturno, but I’m a little less eager about trying any repair command after recovery attempts. Even ‘safe’ fixes can make a messy drive messier. If the data matters, think preservation first, repair second.
What I’d add:
- Check Event Viewer for disk errors like bad blocks or controller resets.
- If it’s an external HDD, feel the drive. If it’s getting weirdly hot or keeps spinning down, that’s a red flag.
- If the partition shows RAW but the used space still looks about right, that’s acctually a decent sign.
- If this is a Seagate or WD external, test the bare drive with another enclosure if possible. Sometimes the USB bridge board is the real problem, not the disk.
One thing people skip: look at SMART data with CrystalDiskInfo before doing big scans. If health is bad or caution, stop hammering it with repeated reads.
For recovery, Disk Drill is still a sensible choice for RAW hard drive recovery because it can find files even when Windows wants to format the disk. I’d recover to another drive only, never back onto the RAW one. If you want a simple walkthrough, this RAW hard drive file recovery guide is easy to follow.
If the drive is clicking, disappearing, or showing 0 bytes, stop DIY stuff. That’s lab territory, full stop.
