I've written some code which uses the diskArbitration framework to unmount (and eject) a disk. It works, in that the disk gets unmounted, but my callback isn't being called, even though the operation is successful. Any chance of spotting the mistake in this code fragment? :- printf("------Wait..."); sleep(1); // instead of sleep, I want to wait on a semaphore here, until the unmount is complete. // unfortunately the callback isn't being called! You'll find hereafter an amended version of your code. For legibility purposes, I kept it very verbose and as as close as possible to your own version. But please check and double-check! I wrote it very quickly and am not very well versed myself into those matters. ;-) void AndygDiskArbCallback( DADiskRef disk, DADissenterRef dissenter, void * context); void AndygDiskArbCallback( DADiskRef disk, DADissenterRef dissenter, void * context) { printf("If I ever see this, my problems are over\n"); if (dissenter == NULL) ((Nothing *)context)->dummy = 0; else ((Nothing *)context)->dummy = DADissenterGetStatus(dissenter) ?
