How to Recover Data from RAW USB Drive? 5 Methods

A RAW USB drive may still contain your files even though Windows or macOS cannot open it. Start with a non-destructive scan, then move to imaging or specialist recovery if the device acts unstable.

Quick answer

Do not format the RAW USB drive. Scan it with Disk Drill, preview the results, then recover files to a different healthy drive. If the USB device disconnects or reports read errors, create a byte-for-byte image before running a full scan.

Stop writing to the USB drive. Formatting, running CHKDSK, initializing the disk, or saving recovered files onto it can overwrite recoverable data. If the device clicks, overheats, or repeatedly disconnects, unplug it plus consider a recovery lab.

When Software Recovery Is Unsafe for a RAW USB Drive

Skip DIY scans when the USB drive becomes hot, has a loose connector, disappears during light use, or causes the computer to freeze. Those symptoms can point to a hardware fault rather than ordinary file-system corruption.

One scan may be harmless for a stable device, but repeated reads can push failing flash memory past the point where it responds. If the files cannot be replaced, a lab should inspect the drive before more power cycles.

Choose the Right RAW USB Recovery Method

Start with the least invasive option that fits the drive's condition.

Top 5 Methods to Recover Data From a RAW USB Drive

01

Scan the RAW USB Drive With Disk Drill

Best first move when the drive appears in Disk Management or Disk Utility

~15–60 min
Difficulty Easy
You need Disk Drill plus a second drive
Works for Windows, Mac

A RAW label usually means the operating system cannot interpret the USB drive's file system. Disk Drill can search the device below that damaged file-system layer, letting you preview recoverable files before saving them elsewhere.

  1. Stop using the RAW USB drive. Do not format it, copy anything onto it, or accept a repair prompt.
  2. Download Disk Drill from the official Disk Drill website, then install it on your computer's internal drive or another healthy device.
  3. Connect the RAW USB drive directly to the computer, open Disk Drill, then select the physical USB device rather than an individual volume.
  4. Click Search for lost data, then allow the full scan to finish if the drive remains stable.
  5. Filter the results by file type, date, or name. Preview several important files to check that they open correctly.
  6. Select the files you need, click Recover, then save them to a healthy drive with enough free space.

02

Create a Disk Image Before Scanning

Safer for a USB drive that disconnects, freezes, or produces read errors

~30 min–several hours
Difficulty Moderate
You need Disk Drill plus free storage
Works for Windows, Mac

Repeated scans put extra strain on unstable flash storage. A byte-for-byte image captures readable sectors in one file, so later recovery attempts can work from the image instead of repeatedly touching the original USB drive.

  1. Find a healthy destination drive with free space at least equal to the RAW USB drive's full capacity.
  2. Open Disk Drill, locate its byte-to-byte backup feature, then select the physical RAW USB device as the source.
  3. Choose the healthy destination drive for the image file. Confirm that the save location is not the damaged USB device.
  4. Start the backup, keep the computer awake, then avoid moving the USB drive during the copy.
  5. When the image is complete, disconnect the original USB drive plus store it safely.
  6. Load or attach the disk image in Disk Drill, scan it for lost data, then recover selected files to a separate healthy location.
i If the image process stalls for long periods or the drive repeatedly vanishes, stop home recovery rather than forcing more read attempts.

03

Carve Files From the USB Drive With PhotoRec

Free fallback when folders or original filenames no longer matter

~30 min–several hours
Difficulty Moderate
You need PhotoRec plus a second drive
Works for Windows, Mac, Linux

PhotoRec ignores the damaged file system, looking for recognizable file signatures instead. It may retrieve photos, documents, archives, or videos from a RAW USB drive, though filenames plus folder structure are commonly lost.

  1. Download the TestDisk package from the official CGSecurity website, then open QPhotoRec for a graphical interface or PhotoRec for the terminal version.
  2. Select the physical RAW USB drive carefully by checking its capacity. Picking the wrong disk can waste hours.
  3. Choose the relevant partition if one appears. If the partition layout is missing, select the whole device.
  4. Open File Formats, then enable only the file types you need to reduce clutter plus scanning time.
  5. Set the recovery destination to a different healthy drive, never the RAW USB device.
  6. Start the search, then inspect the numbered recovery folders after the scan finishes.
i Recovered files may have generic names such as f123456.jpg, so expect to sort results manually.
04

Rebuild the Lost Partition With TestDisk

Useful when partition metadata is damaged but the file system may still exist

~20–90 min
Difficulty Advanced
You need TestDisk plus a disk image
Works for Windows, Mac, Linux

TestDisk can search for lost partitions, display files from a detected partition, or rewrite partition information. This route may restore normal access, but a wrong write can make later recovery harder, so work from an image whenever possible.

  1. Create a complete disk image first. Do not experiment with partition repairs on the only copy of valuable data.
  2. Launch TestDisk with administrator privileges, create a log, then select the disk image or physical USB device.
  3. Confirm the partition-table type suggested by TestDisk unless you know the device uses a different layout.
  4. Choose Analyse, run Quick Search, then highlight a found partition.
  5. Press the file-list key shown on screen. Copy important files to a healthy drive if the expected folders appear.
  6. Use Deeper Search if needed. Write a recovered partition table only when the size, boundaries, file list, plus partition type all look correct.
i Copying files from a detected partition is less risky than writing changes to the USB drive's partition table.
05

Send the USB Drive to a Recovery Lab

Right choice for physical failure, irreplaceable files, or failed software scans

~3–14 days
Difficulty Easy
You need A reputable recovery lab
Works for Physically damaged USB drives

Software cannot fix a broken connector, failed controller, damaged circuit board, or worn-out NAND memory. A lab may access the memory chips directly, though flash recovery can be costly plus results are never guaranteed.

  1. Unplug the USB drive if it becomes unusually hot, smells burnt, appears physically bent, or disconnects every few seconds.
  2. Do not open the casing, resolder the connector, freeze the drive, or run repeated scans.
  3. Write down what happened before the failure, including any drop, power issue, format attempt, or repair command.
  4. Contact two or three established recovery labs, then ask about evaluation fees, return shipping, privacy, plus what happens if no files are recovered.
  5. Describe the exact device model, capacity, symptoms, plus the most important folders or file types.
  6. Pack the drive in an antistatic bag or protective case, then use tracked shipping if the lab is not local.
i For irreplaceable business records or family media, choosing a lab before DIY scanning can preserve the best remaining recovery chance.

Which RAW USB Recovery Method Should You Use?

Scanning the RAW USB drive with Disk Drill is the sensible first move when the device stays connected plus appears in the computer's disk utility. Create an image first if the drive is unstable, use PhotoRec when a free file-carving option is enough, or try TestDisk only if you understand partition layouts. Physical damage or truly irreplaceable data belongs with a recovery lab.

Recover the most valuable files first, save them to another drive, then reformat or replace the USB device only after you verify the recovered copies.

RAW USB Drive Recovery Questions

How do I recover files from a RAW USB drive without formatting it first?
Stop using the USB right away, then try a file recovery tool that can scan RAW storage and copy files to your computer. If the drive keeps asking to be formatted, do not click Format because that can make recovery harder.
What does it mean when a USB drive shows up as RAW?
RAW usually means Windows cannot read the file system on the USB drive, often because of corruption, unsafe removal, or a failing flash chip. Your files may still be there even if the drive looks empty or unreadable.
Which is better for a RAW USB drive, data recovery software or CMD repair tools?
Recovery software is usually the better first step because it focuses on copying your files out safely. CMD repair tools like CHKDSK can sometimes help after recovery, but they can also make things worse if the file system is badly damaged.
Can I use CHKDSK on a RAW USB drive to fix it?
Usually no, because CHKDSK needs a readable file system to work properly. If Windows says the USB is RAW, recover the data first, then decide whether the drive is worth reformatting.
How do I recover deleted photos from a RAW USB flash drive?
Connect the drive, run a recovery scan, then filter results by image formats like JPG, PNG, or HEIC. Save the recovered photos to a different drive so you do not overwrite anything still on the USB.
Why does my USB drive become RAW after I unplug it?
An unsafe removal can interrupt writes to the file system, which can leave the USB unreadable the next time you plug it in. Power loss, bad ports, or a worn-out flash drive can cause the same problem.
What are the first steps before trying RAW USB data recovery?
Do not copy new files onto the USB, do not format it, then check whether it appears in Disk Management. If it shows the correct size, use recovery software right away since the drive is still being detected.
Can I recover data from a RAW USB drive on Mac instead of Windows?
Yes, many recovery tools work on macOS too, so you can scan the USB from a Mac if that is the computer you have available. Just make sure the app supports raw drive scanning before you start.
How much does RAW USB data recovery usually cost?
Software recovery often ranges from free limited scans to paid licenses for full recovery. If the USB has physical damage or is not detected at all, professional recovery can cost more because the work is done in a lab.
Is it safe to format a RAW USB drive if I already backed up most files?
Yes, if you have recovered what matters most, formatting can restore the drive so you can use it again. Still, make sure the backup is complete because a full format will erase what is left on the USB.
What file types can be recovered from a RAW flash drive?
You can often recover documents, photos, videos, archives, audio files, and many more common formats. The exact result depends on how damaged the file system is plus whether the files were overwritten.
Why does my RAW USB drive show the wrong capacity in Windows?
A wrong size reading can mean partition corruption, firmware trouble, or a badly failing drive. If the USB still shows a recognizable capacity, recovery may still work, but a wildly incorrect size is a warning sign.
Can I recover a RAW USB drive if it asks for formatting every time I plug it in?
Yes, that prompt often means the file system is broken, not that the files are gone. Cancel the format message, then use recovery software before you try any repair step.
What is the best free way to recover data from a RAW USB drive?
A free trial recovery tool is often the best starting point because it lets you see what can be found before you pay. If the preview looks good, recover the files to another drive, then decide whether the paid version is worth it.
How do I know if my RAW USB drive is physically damaged?
If it disconnects repeatedly, gets unusually hot, or is not detected in different ports, physical damage is possible. When the computer cannot see the USB at all, software recovery may not be enough.
Should I use a quick format or full format after RAW USB recovery?
A quick format is usually enough if the USB seems healthy after recovery. A full format takes longer and is only worth considering if you want a deeper check before using the drive again.
Can a RAW USB drive recover files if it was used on both Windows and Android?
Yes, cross-device use can sometimes trigger file system damage, but recovery is still possible if the USB is detected. Try to recover the data on a computer first, since phones and tablets usually offer fewer recovery options.
What should I do if the RAW USB drive is not showing in File Explorer?
Open Disk Management to see whether Windows detects the drive at all. If it appears there with the right size, recovery software may still be able to scan it even when File Explorer cannot.
Are there any alternatives to software for recovering RAW USB files?
Yes, you can try copying the drive image first, using a different USB port or computer, or seeking professional data recovery if the drive is unstable. Those options can help when the drive is failing too fast for a normal scan.
How can I avoid getting a RAW USB drive again in the future?
Always use Safely Remove Hardware before unplugging, avoid cheap or counterfeit flash drives, plus keep an extra copy of important files elsewhere. If a USB starts acting flaky, replace it before it turns into a recovery job.
