3/26/2014

This function scans a volume for errors in the FAT and directories, and for lost clusters.

Syntax

DWORD ScanVolumeEx(
  HANDLE hVolume,
  PSCAN_PARAMS psp,
);

Parameters

  • hVolume
    [in] Handle to disk or partition. Call the CreateFile function to obtain a handle to the volume.
  • pdp
    [in, out] Pointer to a SCAN_PARAMS structure used to pass in parameters and receive results of the scan.

Return Value

The following table shows return values for this function.

  • ERROR_SUCCESS
    Occurs if the call to ScanVolumeEx succeeded. Examine the structure returned in the pdp parameter for detailed results.
  • ERROR_GEN_FAILURE
    Occurs when the system could not successfully call GetPartitionInfo on the store passed in hVolume.
  • ERROR_SHARING_VIOLATION
    Occurs when the store specified by hVolume is mounted; mounted stores cannot be scanned.
  • ERROR_READ_FAULT
    Occurs when the system could not read from the store specified in hVolume.
  • ERROR_WRITE_FAULT
    Occurs when the system could not write to the store specified in hVolume.
  • ERROR_UNRECOGNIZED_VOLUME
    Occurs when the store specified in hVolume does not contain a recognized file system; needed file system drivers may not be loaded, or the store may be corrupt.
  • ERROR_DISK_FULL
    Occurs when the store specified in hVolume does not contain enough space to perform the scan.
  • ERROR_CANCELLED
    Occurs when the operation was canceled by the user.

Remarks

To obtain results of a scan, use the correct type of handle. For example, if the store to be scanned is partitioned, use a handle to the partition. If the store is not partitioned, use a disk handle.

If the scan completes, this function returns the scan results through the SCAN_RESULTS structure embedded in the SCAN_PARAMS structure.
