Re: Regarding storage drivers.

there is plug and play notification to the mount manager during the arrival
of volume interface.
Is there any similar notification to mount manager when the volume
goes.(removal of pnp device)
The drive letter is missing in the explorer window.
when a open the disk management console and right click the volume for
properties it shows a messgae saying that there is an internal error and the
property window doesnt appear.

thanks in advance

Thank u Maxim.

I have problem.
I have a mirror filter driver which sits below filesystem driver and above
volume manager.I have a drive which is mirrored between 2 nodes.I make one as
source and the destination.The destination is controlled by my application.no
other application can access it.any IOCTL I send to the destination nodes
gets rejected as my application takes control of that drive.

when I insert a plug and play device to the destination node my mirror drive
is missing in the explorer window as the IOCTL
(IOCTL_MOUNTDEV_QUERY_DEVICE_NAME) send by my mount manager is being rejected.
when I supported the above IOCTL by just passing it thru my driver so that
volume manager takes care of it,now I see the my mirror drive in the explorer
window,but when I remove the plug and play device from the destination node
my drive is missing again.

Initially my mirror drive was missing when I plugged in the pnp device(for
example memory stick).Now after supporting the above IOCTL my mirror drive is
missing when I remove the pnp device.

Is there any thing I need to take care in my filetr drive.

Thaks in advance

when pnp manager detects a pnp device in the system.
which driver will respong to this IOCTL.Is it the partition
manager.partmanager.sys.
or volume manager?????

Volume manager - FtDisk or DmIo

For removable media, Disk or CdRom will respond.

I am I making any sense here.I am confused.who will respond to this IOCTL.

Volume manager.
