What is this IOCTL? (2D9404)

Bob_Kroeter · July 25, 2009, 5:03am

I am seeing an IRP with IoControlCode=0x002d9404 going down the storage stack in Windows 7 with InputBufferLength=48. Is it possible to find the defintion of this ioctl as well as the corresponding data buffer layout?

This looks like IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES in api/winioctl.h.
