AtaPortBusChangeDetected function (irb.h)

  • Article

The AtaPortBusChangeDetected routine notifies the port driver of changes in the device configuration on the indicated channel.

Note  The ATA port driver and ATA miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.

  PVOID ChannelExtension
);

Parameters

ChannelExtension

A pointer to the channel extension.

None

Remarks

The miniport driver uses this routine to report the arrival or removal of any device that is attached to the channel. In response, the port driver will initiate a re-scan to discover and initialize the device.
