How it failed · corrupted & RAW
A RAW drive has lost the grammar, not the words: the structures that describe the file system are damaged, while the files themselves usually sit exactly where they were. The danger isn't the corruption — it's the repair tools that finish the job.

| What you see | What it means | First move |
|---|---|---|
| You need to format the disk in drive X: before you can use it | Windows can't parse the file system — the classic RAW prompt | Never click Format |
| The type of the file system is RAW. CHKDSK is not available for RAW drives. | CHKDSK admitting it can't help here | Don't force it further |
| The file or directory is corrupted and unreadable (0x80070570) | Damaged file records in the MFT | Stop opening files |
| The disk structure is corrupted and unreadable (0x80070571) | Damaged partition or MFT structures | Image before repair |
| Location is not available — X:\ is not accessible. The parameter is incorrect. | File-system corruption, often with bad sectors beneath | Suspect the hardware too |
| This volume does not contain a recognized file system. | Volume metadata lost | The data underneath survives |
| macOS: The disk you inserted was not readable by this computer | The Mac equivalent — with an Initialize button that must not be pressed | Choose Eject, not Initialize |
Your device is logged with its own case reference the moment it arrives. An engineer assesses the fault, confirms what's actually recoverable, and you get a fixed price in writing — no diagnosis fee, no obligation, and no paid work until you say go.
The whole drive is imaged before any repair is attempted — bad sectors mapped, weak areas read last. Corruption plus failing hardware is common, and the image protects against both.
Boot sectors, MFT records and partition tables are rebuilt on the image, where a wrong turn costs nothing and can be undone.
Where the MFT is too far gone, files are carved by signature from the image — contents complete, structure reconstructed as far as the evidence allows.
Before you pay the recovery fee you approve a full listing of what came back. Your data returns on new media with free return postage, and the case only closes once you've confirmed everything opens on your side.
The repair-tool paradox: the utilities most people reach for first — CHKDSK, First Aid, free 'fix RAW drive' tools — all write to the drive they're repairing. On corrupted-but-healthy media they sometimes work; on corrupted-and-failing media they routinely turn a full recovery into a partial one. Image first costs a day; repair-in-place can cost the lot.
Pulled mid-write one evening; by morning it wanted formatting. Imaged in full, the boot sector and a damaged MFT mirror rebuilt on the copy, and fifteen years of a translator's client work returned with its folder tree intact.
Formatting writes a new, empty file system over the damaged one, destroying the structures recovery uses to restore your names and folders. Decline the prompt; recover first.
One whose file system Windows can no longer interpret — usually a damaged boot sector, MFT or partition table. The user data beneath is typically intact.
Not here. It refuses RAW volumes anyway, and on failing hardware its repair passes accelerate the failure. Repairs belong on an image of the drive, not the drive.
Unsafe removal mid-write is the single most common cause, but it damages the paperwork, not the files. It's also one of the most cleanly recoverable faults we see.
Every restart of a damaged device costs data. Open a case first — the diagnosis is free either way.
