In a perfect world, bcache could see when the drive is spun up and write it opportunistically, or one day, whichever occurs first. > thing is there's all kinds of partitions on your hard disk no doubt. Are they *ALL* unmounted or mounted RO except the bcache-enabled one? I have the rootfs on the SSD (a different partition than bcache), so on the hard disk there is only one partition and the one mount is the bcache backing one.
