Re: Regarding storage drivers.

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.
