A RAW USB drive is not necessarily empty. Leave it unformatted, recover the files to separate storage, then rebuild the USB only after the data is safe.
Do not format the RAW USB drive. If it appears with the correct capacity, scan it with Disk Drill, preview the important files, then recover them to another device. Create a byte-for-byte image first if the USB is unstable.
Stop writing to the USB drive. Formatting, running repair tools, saving recovered files back to it, or accepting an initialization prompt may overwrite recoverable data. A clicking sound is unusual for flash media, but heat, disconnects, 0-byte capacity, or a damaged plug are reasons to stop DIY work.
Scans storage that cannot mount normally · Previews found files before recovery · Available for Windows plus macOS
A RAW label usually means the computer cannot interpret the USB drive's file system. Disk Drill can scan the physical device without requiring that damaged file system to mount normally. If the USB disconnects, freezes, or reports read errors, create a byte-for-byte image first.
Before running several long scans, check whether the USB data exists elsewhere. Camera imports, email attachments, cloud folders, old computers, NAS snapshots, plus automatic backups often contain more than people expect.
TestDisk can search for lost partitions, inspect recognized file systems, plus copy files to another disk. Start with its read-oriented listing and copy features. Do not write a replacement partition table unless you have a full image plus understand the proposed layout.

to list files. If the folder tree looks correct, select the needed items plus press
C
to copy them.PhotoRec ignores the damaged file system, then searches storage for known file signatures. This can recover documents, photos, video, plus archives from a severely corrupted USB, though original names or folders are often lost.
Software cannot fix a cracked connector, failed controller, damaged NAND chip, or unstable electrical connection. A specialist may repair the electronics or read the memory chips directly, though USB flash recovery can be expensive.
RAW is the operating system's way of saying it cannot identify or safely mount the current file system. The cause might be a damaged FAT32 or exFAT structure, an interrupted write, an unsafe removal, a failing controller, or corruption in the partition information.
The RAW label alone does not prove the files were erased. It also does not tell you whether the trouble is logical or physical, which is why the drive's capacity, stability, temperature, plus connection behavior matter.
Repair is not the first goal when the USB contains files you still need. Commands that modify file-system metadata can remove damaged records that recovery software might otherwise interpret. Windows may also report that CHKDSK is unavailable for a RAW volume.
Make an image or recover the files first. Once two verified copies exist elsewhere, you can format the USB for testing, though replacing an unreliable flash drive is usually the sensible choice.
Match the method to the drive's condition, not just the RAW message.
| Method | Best for | Time | Success rate |
|---|---|---|---|
| 1. Scan the RAW USB Drive With Disk Drill TRY FIRST | Stable USB detected at the correct capacity | ~15–60 min | ● 82% |
| 2. Restore the USB Files From Another Copy | Files previously synced or backed up | ~5–30 min | ● 100% |
| 3. Copy Accessible Files With TestDisk | Recognizable lost partition or folder tree | ~20–90 min | ● 68% |
| 4. Carve Files From the USB With PhotoRec | Severe file-system damage | ~30 min–several hours | ● 57% |
| 5. Send the USB Drive to a Recovery Lab | Physical damage or unstable hardware | ~3–14 days | ● 65% |
For a USB drive that remains stable plus shows its normal capacity, scan it with Disk Drill first. Its preview feature lets you check results before committing to a large recovery job. Use TestDisk if the original partition or folder tree is detectable, while PhotoRec is better suited to carving files from badly damaged structures.
If the USB overheats, disconnects, reports 0 bytes, or has a broken connector, stop scanning it. A recovery lab is more appropriate because the problem is probably below the file-system level.
Recover everything to a different physical drive, verify the files, then replace or reformat the problem USB instead of trusting it with the only copy.
