NTFS
The File or Directory Is Corrupted and Unreadable
Scan before chkdsk rewrites the damaged NTFS structures.
Written by the Refindo Recovery Team · Published · Updated
The error "The file or directory is corrupted and unreadable" points at damaged NTFS metadata — usually the Master File Table or the index that lists a folder's contents. It can hit a single folder or the whole drive, and it often follows an unsafe removal, bad sectors, or an interrupted write. The data the records describe is frequently still on the disk; it is the structures pointing to it that are broken. That is why scanning before chkdsk gives the best result.
Do not run chkdsk yet
The error is about broken structures, not erased files. The data those records point to is usually still there, so scan the drive before chkdsk rewrites the metadata a recovery would rely on.
- Do not run chkdsk /f as your first move on the affected drive.
- Do not keep reopening the corrupted folder and retrying.
- Do not copy new files onto the drive before scanning.
- Recover to a separate disk, not back onto the corrupted drive.
What causes this NTFS error
- A damaged Master File Table or folder index on NTFS.
- Bad sectors landing in the file-system metadata.
- An unsafe removal or power loss during a write.
- A failing drive or cable introducing read errors.
How to scan past the corruption
Refindo can scan a volume showing this error as long as Windows still detects it, reading past the damaged records to find files. It does not modify the source the way chkdsk does.
- Note whether the error affects one folder or the whole drive, and check Disk Management.
- Reconnect the drive directly with a known-good cable to rule out read errors.
- Open Refindo and select the affected NTFS volume without running chkdsk.
- Run Quick Scan, then Deep Scan to rebuild files from surviving records and signatures, and recover elsewhere.
When the corruption keeps spreading
- The error spreads to more folders or the whole drive over time.
- The drive holds the only copy of critical data.
- Disk Management or SMART reports bad sectors or drive errors.
- The drive disconnects or reads with constant errors.
The MFT, folder indexes, and bad sectors
What the error tells you about NTFS
This message means Windows reached a file record or a folder index and found it inconsistent — a broken entry in the Master File Table, or a damaged B-tree index that lists a folder's contents. When a folder's index is corrupt, everything inside it becomes unreachable through normal browsing even though the files still exist. Recovery tools bypass the broken index and read the underlying records and data directly.
When bad sectors are behind it
If the corrupted records sit on failing sectors, the error can recur or spread as the drive degrades, and each read attempt stresses the drive further. Checking SMART status helps tell software corruption (often a one-time event from an unsafe removal) from hardware decline (worsening over time). On a failing drive, imaging or recovering sooner rather than later protects more data, because continued use can turn recoverable sectors into unreadable ones.
Frequently Asked Questions
What does "the file or directory is corrupted and unreadable" mean?
It means an NTFS structure — the Master File Table or a folder index — is damaged. The files it points to are often still on the drive and recoverable.
Should I run chkdsk to fix it?
Not before recovery. chkdsk can rewrite the damaged records and move files into found.000 folders, reducing what a scan recovers. Scan first.
Only one folder is affected — are those files gone?
Usually not. A corrupted folder index makes its contents unreachable through Explorer, but the files still exist and a scan can recover them.
Why does the error keep coming back?
A recurring or spreading error often means bad sectors on a failing drive. Recover your data promptly and check the drive's SMART status.
Can I recover the files without fixing the drive?
Yes. A read-only scan recovers files to another drive without repairing the source, which is the safer order when the data matters.
Scan before you repair
Run a read-only scan first, preview what is recoverable, then save selected files to a different drive.
