 * }

Q196120

-

The information in this article applies to:


 * Microsoft Win32 Device Driver Kit (DDK) for Windows NT, version 4.0

-

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.
