It could be IOCTL_DISK_CLUSTER_TEST and it can be ignored. Generally you
can ignore IOCTLs that are not documented either in the docs or in the
source code (i.e. reverse engineering scsiport from disk.sys gives you a
good hint about what IOCTLs you need to be concerned with.)

Subject: [ntdev] unkown IoControlCode == 0x4144c
Hi
I’m developing a ScsiPort driver.
I receive a device control request IRP with IoControlCode == 0x4144c.
Device:CONTROLLER (0x4)
Function:0x513 <=What`s this?
Access:FILE_ANY_ACCESS
Method:METHOD_BUFFERED
I tried to find it from NTDDK\inc*.h ,
But I can’t.
Does anybody knows what code is it?
