The Storage Family does not return EACCES on a read in any other context, however, it is plausible the error came from a driver below the family, of course. This is the case... the device was closed, but I'm pretty sure it wasn't by our driver. If I load my FileSystem from within a login the strategy succeeds. What I find is when I log out and then back in (even as the same user) I get the EACCES error. I initially ran into this problem by starting my FileSystem on boot and trying to do tests as a user. I have traced using gdb into the media layer which returns the error. I can only assume that another entity is closing the device (maybe prompted by the logout or login). This is why I want to have a debug version of IOStorageFamily so I can see when the device is closed. Any ideas? Thanks.

I need to be able to build and install a debug version of IOStorageFamily. Building it is easy (with either ProjectBuilder or pbxbuild)... the problem is when I install and restart the system I get the "No Entry" symbol. Could somebody explain why my kext isn't working... * do I have to copy more than just the kext? * is there a difference between building with ProjectBuilder or pbxbuild?
