DEVICE_DSM_RANGE_ERROR_INFO structure

Description

The DEVICE_DSM_RANGE_ERROR_OUTPUT (or DEVICE_DSM_RANGE_ERROR_INFO) structure stores information about whether one or more logical block ranges contain any media errors.

Members

`Version`

Version of this structure. Set to sizeof(DEVICE_DSM_RANGE_ERROR_OUTPUT).

`Flags`

Flags associated with the range error information. Possible values are:

Value	Meaning
DEVICE_STORAGE_NO_ERRORS	There are no media errors in any of the requested ranges.

`TotalNumberOfRanges`

Number of DEVICE_STORAGE_RANGE_ATTRIBUTES structure(s) needed to satisfy a DeviceDsmAction_GetRangeErrorInfo request.

`NumberOfRangesReturned`

Number of DEVICE_STORAGE_RANGE_ATTRIBUTES structures returned in Ranges.

`Ranges`

Array of DEVICE_STORAGE_RANGE_ATTRIBUTES structure(s) in which to return media error information.

Remarks

The output block in the payload of an IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES request is formatted as a DEVICE_DSM_RANGE_ERROR_OUTPUT structure when the action is DeviceDsmAction_GetRangeErrorInfo. See DEVICE_DSM_ACTION Descriptions for more details about this action.
