| Name | Data Type | Default Value | Qualifiers |
| Name | Data Type | Value |
| LBAEnd | uint64 | |
| Description | string | This property is used by a client to specify the end of a region to be tested. If LBAEnd is NULL, then the default value is the number of the last disk sector. If multiple target HDDs are selected, then the same end address is used for each. |
| ModelCorrespondence | string | CIM_RAIDDiagnosticServiceCapabilities.RegionSupported |
| LBAStart | uint64 | |
| Description | string | This property is used by a client to specify the start of a region to be tested. If LBAStart is NULL, then the default value of 0 is used. If multiple target HDDs are selected, then the same start address is used for each. |
| ModelCorrespondence | string | CIM_RAIDDiagnosticServiceCapabilities.RegionSupported |
| Seed | uint32 | |
| Description | string | This property is used by a client to specify the seed that initiates the random number sequence used by the test. In order to replicate the same random number sequence for successive tests, one should use the same seed value. If this property is NULL, then the diagnostic randomly selects its own seed using a vendor-specific algorithm. If multiple target HDDs are selected, then the same seed is used for each. |
| ModelCorrespondence | string | CIM_RAIDDiagnosticServiceCapabilities.SeedSupported |
| TargetHDDs | string[] | |
| Description | string | This array property is used by a client to specify the HDDs managed by the RAID controller to be tested. If this property is NULL, then all HDDs are tested. Otherwise, the value of each array entry shall be the value of the DeviceID property for the corresponding CIM_DiskDrive instance to be tested. |
| ModelCorrespondence | string | CIM_RAIDDiagnosticServiceCapabilities.TargetHDDsSupported, CIM_DiskDrive.DeviceID |
