what does STATUS_NO_MEDIA_IN_DEVICE mean??

when I pass IOCTL_DISK_GET_PARTITION_INFO_EX to the partition device object
I get STATUS_NO_MEDIA_IN_DEVICE errorcode.
what does it mean???
ntstatus.h says that there is no disk in the drive.
what does that mean???will the above IOCTL fail for dynamic disk with this error code.
I thought if it is dynamic disk it will fail only with STATUS_INVALID_DEVICE_REQUEST errorcode.
any help on this.

I dont have the machine details.jus the log.
