Hi there,

I am developing a Volume filter. During debugging on VMWare i am seeing that for each volume AddDevice is being called twice. There are two volume on my system and i am getting 4 calls to AddDevice. Is iit right to get calls to AddDevice twice for the same volume or i am messing something up.

Thanks

Have you run CHKINF?

Check your INF file. My experience has been that AddDevice gets called at
least twice if you have the following sequence:

[Manufacturer]
%Mfg%=MyDeviceSection,NTX86,NTamd64

[MyDeviceSection]
% MyDevice.DeviceDesc%= MyDevice, root\MyDevice

[MyDeviceSection.NTX86]
% MyDevice.DeviceDesc%=VED MyDevice, root\ MyDevice

[MyDeviceSection.NTamd64]
% MyDevice.DeviceDesc%= MyDevice, root\ MyDevice

Drop the non-processor specific section. Or, remove the NTX86 and NTAMD64
sections since it will default to the processor you are installing upon.
