I have BusLogic controller and 2 disks, jumpered to be spinned up
via START command. I have instructed the controller not to send
the command to the 2nd disk since I do not currently use it, I just
have it 'in'. Hovewer, linux spins up the second disk. It is not
a *problem*, I was just wondering why is linux doing that?
Thank you,
Linux spins up a disk if it returns NOT READY at boot time, regardless of
whether you've told the host adapter not to do it itself. See sd_init_onedisk
in linux/drivers/scsi/sd.c.
