HDD spin up

[wintermute000]

I have spindown on idle working fine, and have a query re: spin up.

My system appears to spin up the drives sequentially - you can hear it clearly, and as a consequence takes ages (around 30 seconds for all 6 drives to come online).

Is there any way to make the drives spin up concurrently? I have a 400W seasonic PSU so no worries on the power front. my drives are all SATA into the motherboard directly and I'm using ataidle to achieve the spindown.

I even wrote a script to do this and even the script (which sequentially calls ataidle -i) runs completely serial i.e. each ataidle command waits to completely finish spinning up before proceeding to the next.

Please no OT discussions on the merits or downsides of spindown.

Thanks

Check out your bios settings once. My Supermicro motherboard has options for staggered drive start-up.

checked, nothing. (interestingly enough manual has the staggered option described but the actual BIOS doesn't - it is running latest, manual is probably describing release)

Can multiple instances of ataidle run at once? If so, rewrite your script to start multiple instances before the first one returns.
