FSCTL_REPAIR_COPIES IOCTL (winioctl.h)

Repair data corruption by selecting the proper copy to use. This control code was introduced in Windows 8 and Windows Server 2012 for use on Storage Spaces and Streams on NTFS and ReFS and non-integrity streams on ReFS (streams with integrity on ReFS handle this automatically.)

To perform this operation, call the DeviceIoControl function with the following parameters.

BOOL DeviceIoControl(
 (HANDLE) hDevice, // handle to file or directory
 FSCTL_REPAIR_COPIES, // dwIoControlCode
 (LPDWORD) pInBuffer, // REPAIR_COPIES_INPUT
 (DWORD) InBufferSize, // size of input buffer
 (LPDWORD) pOutBuffer, // REPAIR_COPIES_OUTPUT
 (DWORD) OutBufferSize, // size of output buffer
 (LPDWORD) lpBytesReturned, // number of bytes returned
 (LPOVERLAPPED) lpOverlapped // OVERLAPPED structure
);
