Reggie --

Thanks for the pointers. I finally got around to working on this some more, and after much reading I have one more road block. After changing my class to be based of IOBlockStorageDevice the module will not load. When doing a "kextload -tv" I get the following error:

kextload: extension IOSDHCIBlockDevice.kext/ appears to be valid
Can't find superclass for 18IOSDHCIBlockDevice : 20IOBlockStorageDevice
kextload: a link/load error occured for kernel extension IOSDHCIBlockDevice.kext/
load failed for extension IOSDHCIBlockDevice.kext/
(run kextload with -t for diagnostic output)

Anyone have some advice, I will be glad to post code if needed.

Does your kext's Info.plist file have an OSBundleLibraries entry that includes com.apple.iokit.IOStorageFamily with a version of 1.0.0?
