BUG: IOCTL SMART_GET_VERSION Returns Invalid bIDEDeviceMap Info

ID: Q196120

The information in this article applies to:

SYMPTOMS

The IOCTL call for SMART_GET_VERSION returns invalid bIDEDeviceMap information in the GETVERSIONINPARAMS structure. If the IOCTL succeeds, the bIDEDeviceMap will always be 1. The bIDEDeviceMap is a bitmask that typically provides device information, indicating IDE or Atapi, primary or secondary controller, drive 0 or drive 1.

NOTE: SMART stands for Self-Monitoring, Analysis and Reporting Technology.

The SMART_GET_VERSION IOCTL is sometimes referred to as the DFP_GET_VERSION IOCTL. NOTE: DFP stands for Disk Fault Protection.


CAUSE

The Atapi.sys driver incorrectly fills in the bIDEDeviceMap information when the SMART_GET_VERSION IOCTL is issued.


RESOLUTION

There is no resolution at this time.


STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.
