IOCTL_DISK_FORMAT_TRACKS_EX

IOCTL_DISK_FORMAT_TRACKS_EX control code

Is similar to IOCTL_DISK_FORMAT_TRACKS, except that it allows the caller to specify several more parameters. The additional extended parameters are the format gap length, the number of sectors per track, and an array whose element size is equal to the number of sectors per track. This array represents the track layout.

Input Parameters

The buffer at Irp->AssociatedIrp.SystemBuffer contains the FORMAT_EX_PARAMETERS data. Parameters.DeviceIoControl.InputBufferLength in the I/O stack location of the IRP indicates the size, in bytes, of the buffer.

Output Parameters

The device driver returns an array of BAD_TRACK_NUMBER values to the buffer at Irp->AssociatedIrp.SystemBuffer. BAD_TRACK_NUMBER is currently defined as a WORD on 32-bit systems.

I/O Status Block

The driver sets the Status field to STATUS_SUCCESS. Otherwise, the driver sets the Status field to STATUS_INVALID_PARAMETER if the input buffer length is < sizeof(FORMAT_EX_PARAMETERS) or if the format parameters supplied by the caller will not work on the drive to be formatted.

Requirements
