In order to read _current_ HFS data from a mounted disk we need to flush the HFS cache to disk before we start to read. - Calling sync() does not do the job - data on disk is not updated with HFS cache. - Opening the disk with open("/dev/rdsk0s10", O_RDWR) or (open("/", O_RDWR) and calling fsync(diskfd) or ioctl(diskfd, DKIOCSYNCHRONIZECACHE) does not do it - data on disk is not updated with HFS cache. - Starting Disk Utility does the job - afterwards the HFS data on disk is updated with current information. Any idea how Disk Utility forces to flush the HFS cache to disk, and how we can do it in our code (without having to start Disk Utility ;-))? This email sent to site_archiver@lists.apple.com
