I have a single WD Green HDD which would serve as a backup.
However, it's just loud (the oscillation of the HDD, etc) and just runs for nothing. It'd be only for backup and that's it.
So far, I wrote a script back then which can power down a HDD (and power up, vica versa). Literally. Once you power it down, it won't come up until you run the other .bat , or issue the command from 'cmd'. It uses smartctl
.
But how could I prevent the PC from even powering it up before I want? Is there a .. hardware switch? Or this is only possible with an external USB HDD case? (Because ... if I do the power down stuff, it takes at least 4 spin up, spin down one day. Like. Start -> spin up; I stop it -> Spin down; Then if I want to backup -> Spin up; Finish with backup -> Spin down.)
