CDAUDIO Filter Driver Dynamic Load
Hi, Is there a way that I can get the CDAUDIO filter driver example in the DDK to load and unload dynamically? I have used the addfilter app in the DDK to install it but the driver does not load until the next reboot. Thanks Ceri -----Original Message----- From: Siddharth Aggarwal [mailto:xxxxx@persistent.co.in] Sent: 28 March 2003 09:38 To: File Systems Developers Subject: [ntfsd] Re: File owner of NTFS Thanks for your reply. I used the GetSecurityInfo() + LookupAccountSid() APIs and they seem to work. But the only problem is that for most files on my C drive, the account name is reported as "Everyone". On the other hand, for files on other drives, the account is correctly reported as "Administrator" or other valid users (actually visible via the NT user manager) What is the reason for this behavior?

RE: CDAUDIO Filter Driver Dynamic Load
You cannot dynamically add filters to the middle of a driver stack. Thus, it isn't generally possible to have a device filter load properly until the next boot of the system. The exception is that you may add a new driver to the TOP of the stack - in this case the I/O Manager will adjust to send new requests to the new top driver. Other OS components, however, may not handle a new driver nearly so well.

RE: CDAUDIO Filter Driver Dynamic Load
Tony, What I'm trying to achieve is to filter SCSI Commands sent to a CDROM drive. What would be the best approach for me to do this while being able to load the driver dynamically? I am very new to programming drivers so if I sound un-knowledgeable then it's because I am.

RE: CDAUDIO Filter Driver Dynamic Load
For w2k+, make a PnP filter and use UpperFilters or LowerFilters to install it. On NT4, you will need a boot-loaded driver.

RE: CDAUDIO Filter Driver Dynamic Load
