This email sent to site_archiver@lists.apple.com Hi, I have 3 partitions created on a disk and have written a filter scheme driver, which matches on ContentHint property of these partitions and successfully loads my driver. But after loading the driver, it is exposing only one IOMedia object instead of 3 IOMedia objects for all 3 partitions. For this I have created one media object in the start() routine in my filter scheme driver as mentioned in SampleFilterSchemeDriver code in Mass_Storage.pdf If I want to expose all the partitions as IOMedia objects through my filter scheme driver then How will i create IOMedia objects for all partitions and how will I iterate through all the IOMedia objects created by my driver from user space application. If your driver is set up properly you should have a separate instance of the driver loaded for each partition, and each instance will publish a new IOMedia object. Can you please run "ioreg -lw 0" and post the part of the output where it shows your three partitions? That will help us understand what behavior you're seeing. http://developer.apple.com/technicalsupport smime.p7s
