Hi !
I am working on a software power management for my HDDs connected to the Raspberry Pi 4 USB. My Python script will put in standby a drive after a period of idle time. The problem is that I want to sync the drive first, before puting it in standby. The only command I know is the `sync`, but they say that this flushes the buffers of all drives connected to the system. Or not ?
What I want to do is that, if I put a drive in standby and I'm not reading/writing it, it must not wake up when I shutdown the Pi and the system unmount all the partitions. Or this is not possible even if I find a way to sync the drive before standby ?
