Hi all,
I am going a bit nuts trying to get something working. I have spent far
too long trying to solve this one problem, so it’s probably something
simple.
What I am trying to do is, I have a disk that has a non standard
partition map. I need to have these partitions mount as drives
(accessible via drive letters). So far I have written a bus driver that
enumerates all of the partitions, creates PDOs for them…ultimately I
call IoRegisterDeviceInterface(…, &MOUNTDEV_MOUNTED_DEVICE_GUID,…)
for each device object representing a partition.
I do respond to a bunch of IOCTLs, but I never see the ones for the
mount manager (IOCTL_MOUNTDEV_QUERY_UNIQUE_ID,
IOCTL_MOUNTDEV_UNIQUE_ID_CHANGE_NOTIFY,
IOCTL_MOUNTDEV_QUERY_DEVICE_NAME)
Any tips on what I might be missing?
Thanks
The best way is to filter reads and writes to sector 0 and assemble
the standard partition table in it on the fly.
