A RAW drive is unreadable to the operating system, but its files may still be present. Start with the least destructive option, then escalate based on the drive's condition.
Do not format the RAW drive or save anything to it. If the device stays connected without strange noises, scan it with Disk Drill, preview the results, then recover files to a different disk. Image unstable media before scanning it.
Stop using the affected drive. Formatting, repair commands, fresh files, or repeated scans can reduce recovery options. Power it off if it clicks, grinds, overheats, or keeps disconnecting.

The percentages are rough planning estimates, not guarantees. Drive condition matters more than the tool.
| Method | Best for | Time | Success rate |
|---|---|---|---|
| 1. Scan the RAW Drive With Disk Drill TRY FIRST | Stable, visible RAW volumes | ~15 min | ● 78% |
| 2. Create a Byte-to-Byte Disk Image | Slow or mildly unstable media | ~1–8 hr | ● 72% |
| 3. Restore the Files From a Backup | Files covered by a recent backup | ~10 min | ● 98% |
| 4. Rebuild the Lost Partition With TestDisk | Lost partitions on healthy disks | ~30–90 min | ● 55% |
| 5. Send the Drive to a Recovery Lab | Physical failure or critical files | ~3–14 days | ● 70% |
Do not run a long scan on a hard drive that clicks, spins down unexpectedly, disappears during reads, or reports rapidly increasing hardware errors. Each extra power cycle can leave less readable data for a lab.
A broken USB cable, weak power supply, or faulty enclosure can mimic drive failure. You may test one known-good cable or compatible adapter, but stop if the symptoms continue.
RAW is not a file system you normally choose. Windows commonly uses the label when it cannot identify or mount the expected NTFS, exFAT, or FAT structure. The cause may be damaged metadata, a missing partition, unsafe removal, bad sectors, encryption, or hardware trouble.
This distinction matters. Reformatting creates a usable empty file system, while recovery tries to copy the old files out first. Treat those as separate jobs.
A RAW label often means the operating system cannot understand the file system, not that every file has vanished. Disk Drill can scan the physical device without requiring you to format it first.
An image preserves readable sectors in one file, which lets you scan a copy instead of repeatedly stressing the original device. Use this route before a long recovery scan if the drive behaves oddly but remains readable.
A recent backup can sidestep RAW-drive repair completely. Check backup dates carefully since the newest snapshot may have been made after the volume became unreadable.
TestDisk can search for missing partitions, inspect boot-sector details, or copy files from structures it recognizes. Its write options change disk metadata, so work from an image whenever possible.
P
on a candidate partition to see whether your expected folders appear.Software cannot repair damaged heads, failed controller hardware, seized motors, or broken flash components. A qualified lab can diagnose the device with tools meant for unstable media.
Disk Drill is the practical first move for a stable RAW drive that still appears in Disk Management or Disk Utility. Preview important results before recovery, then save them somewhere else.
Create an image first if the device is slow or unreliable. Use a backup when one exists, reserve TestDisk for careful partition work, then choose a recovery lab at the first sign of physical failure.
Start with the least destructive method, recover priority files first, then verify every copy before formatting or reusing the original drive.
