Files that disappear after CHKDSK? They may be detached from their original folders, saved as CHK fragments, or still recoverable from disk. This guide explains 4 practical solutions to recover files deleted by CHKDSK.
CHKDSK is a Windows file-system checking and repair utility, not a file-deletion or data-recovery tool. Running CHKDSK without repair parameters reports a volume's status. Parameters such as /frepair logical file-system errors, while /ralso looks for bad sectors and attempts to recover readable information. Those repairs can change directory entries, indexes, allocation records, or links between filenames and stored data.
Therefore, CHKDSK does not normally target healthy files, but files may seem deleted after it repairs inconsistent metadata. A damaged directory entry can be removed, a lost cluster chain may be detached from its original name, or readable fragments may be placed in a FOUND.000, FOUND.001, or similar folder as FILE0000.CHK. If the underlying storage is physically failing, unreadable sectors can also make part or all of a file unavailable.
Minimize writes after the loss. Do not copy new files to the volume, install software on it, initialize it, or run another repair pass. If a drive disconnects, clicks, reports the wrong capacity, or disappears from Disk Management, disconnect it and consider a professional recovery service.
Start with the least invasive matching method. A FOUND folder can provide quick clues, backup methods retrieve earlier copies, and a recovery scan is useful when neither is available. The data recovery results depend on the original corruption, later writes, and device condition.
On FAT-family volumes, CHKDSK can save lost allocation chains as .CHK files. A CHK file may be complete, partial, or unidentifiable. Work only on copies so the original fragments remain available.
Step 1. Open File Explorer, select View > Show > Hidden items, and inspect the root of the affected drive. If necessary, open Folder Options> View and temporarily clear Hide protected operating system files. Restore that protection setting after the check.
Step 2. Look for FOUND.000, FOUND.001, or another FOUND-number folder. If access is allowed, copy the entire folder to a different healthy drive before opening or renaming anything.
Step 3. Sort copied CHK files by size and date. Use a trusted file-type identification tool or inspect a copy with an application that supports the expected format.
Step 4. If the original file type is known, rename only a copy from .CHK to the likely extension, such as .jpg or .docx, and test it. Do not mass-rename every fragment. Some files are split across multiple chains, so a new extension cannot repair missing content.
You can use Backup and Restore (Windows 7) when it contains a backup made before CHKDSK changed the volume. It restores a stored copy rather than reconstructing data from the affected disk.
Step 1. Connect the disk that contains the backup. Open Control Panel > System and Security > Backup and Restore (Windows 7).
Step 2. Select Restore my files. If Windows does not show the expected set, choose Select another backup to restore files from and locate the correct backup.
Step 3. Use Search, Browse for files, or Browse for folders to add the missing items. Check that the backup date precedes the CHKDSK incident.
Step 4. Restore to a different folder first when possible. After the process finishes, open the restored files and confirm that the selected backup version contains the required data.
File History can also restore earlier versions from protected personal folders only if it was enabled before the loss. Connect the original File History drive or its network location.
Step 1. Open Control Panel > System and Security > File History, then choose Restore personal files.
Step 2. Browse to the folder that previously contained the missing items. Use the left and right arrows to review versions from before CHKDSK ran.
Step 3. Select the required files or folders. Preview a file when possible to confirm that it is the correct version.
Step 4. Select the green Restore button to return the item to its original location. To avoid replacing a current file with the same name, right-click Restore and choose Restore to when available.
If no useful FOUND folder or backup exists, a scan can look for deleted entries and recognizable data. AOMEI FastRecovery is suitable for Windows logical data loss when the device is detected. Install it elsewhere and recover to a separate healthy disk.
Step 1. Launch AOMEI FastRecovery and choose Deleted Files Recovery or the recovery entry that best matches the incident.
Step 2. Select the drive on which CHKDSK ran and click Scan. Confirm the drive letter, capacity, and device model when several disks are connected.
Step 3. Browse results by path or file type. Use search, filters, and preview to identify relevant files. If the first scan is incomplete, use Deep Scan when available and allow it to finish.
Step 4. Select only the needed files, click Recover, and choose a different healthy disk. Open important files and compare their sizes and contents with what you expected.
#1. Should I run CHKDSK again if files are still missing?
Usually not before recovery. Another repair pass can modify file-system metadata again. First copy accessible data, inspect FOUND folders, restore a backup, or scan the drive.
#2. Can every CHK file be converted back to its original format?
No. Renaming works only when the fragment contains a sufficiently complete file and the correct format is known. Some CHK files contain partial or combined data and will remain unusable.
#3. Why is there no FOUND.000 folder?
CHKDSK may not have saved lost chains, the folder may use another number, protected files may still be hidden, or the relevant records may no longer be available. The absence of the folder does not prove that recovery is impossible.
#4. Does CHKDSK /r recover deleted files?
No. The /rparameter locates bad sectors and attempts to recover readable information, but it is not a deleted-file recovery command. It can change the file system while repairing it.
#5. Can I recover data from an SSD after CHKDSK?
Possibly, but recovery is less predictable if deleted blocks have been cleared. Stop writes and do not install the recovery application on that SSD.
To recover files deleted by CHKDSK, preserve the affected drive first. Check a copied FOUND.000 folder for usable CHK fragments; use AOMEI FastRecovery when no backup exists and the disk is stable, which supports data recovery from external hard drives as well as local drives; or restore a known copy through Backup and Restore (Windows 7) or File History. Save every recovered item to another healthy disk and verify its contents before making further repairs or returning the source drive to normal use.
