How can I make a HDD shut down automatically if it is not being used?
I recently installed Windows in dual boot with Linux (on two different SSDs) and I noticed that Windows automatically "shuts down" or stops the HDD if it is not being used.
I have a HDD (WD) connected by SATA cable where I usually keep my games. The HDD is not always in use but it is always constantly running and honestly the noise it makes is quite noticeable. I'm sure I don't have any program in the background using it constantly.
I have already tried to solve this problem using hdparm and hd-idle and although in theory they work I still hear the noise from the HDD.
You're viewing a single thread.
Checkout smartctl. You can either force shutdown immediately or after some idle time. Command is something like this:
smartctl -n -s standby,VALUE /dev/sda with value either "now" or something between 0 and 255. From the manpage:
Values from 1 to 240 specify timeouts from 5 seconds to 20 minutes in 5 second increments. Values from 241 to 251 specify timeouts from 30 minutes to 330 minutes in 30 minute increments. Value 252 specifies 21 minutes. Value 253 specifies a vendor specific time between 8 and 12 hours. Value 255 specifies 21 minutes and 15 seconds.
Value 252 specifies 21 minutes.
That's interestingly specific. Any idea why?

The ATA specification takes the values that way. https://people.freebsd.org/~imp/asiabsdcon2015/works/d2161r5-ATAATAPI_Command_Set_-_3.pdf252 * 5 sec = 1260 sec or 21 min. I wonder what 254 does...
Also, why is 255 21 minutes and 15 seconds? And why is there no 254?
