Sending IOCTL from AddDevice routine

OSR_Community_User · July 19, 2004, 2:03pm

Hi,

My driver is a disk class filter driver. Is it legal to send
IOCTL_STORAGE_QUERY_PROPERTY from my AddDevice routine on w2k or w2k3?

Thanks,
JT

Better to do this from MN_START_DEVICE.

Did you mean that you can do it in AddDevice but better do it from
MN_START_DEVICE?

Thanks,
JT

There is no guarantee that the target PDO is operational when your AddDevice
routine is called.

At this point our geek chorus ought to chime in:

“Why don’t you tell us what you are trying to do rather than how you are
trying to do it?”

Note that PnP queries are legitimate in AddDevice, and perhaps they would
satisfy your needs.

You should wait until IRP_MN_START_DEVICE.

Better to not send any requests down the stack from AddDevice. They can
fail.
