ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6

Hey,

I have 2 HDDs and I'm trying to put one of them to sleep when I am not using it (it's a spinning disk so the noise is annoying and drains power when on battery..)
I do that with

hdparm -Y /dev/sda

However periodically something turns it on and I have identified it as an event in dmesg:

[ 3167.076431] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6
[ 3167.076434] ata1.00: waking up from sleep
[ 3167.076437] ata1: hard resetting link
[ 3167.396660] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[ 3169.053096] ata1.00: configured for UDMA/100
[ 3169.053113] ata1: EH complete
[ 3767.460103] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6
[ 3767.460106] ata1.00: waking up from sleep
[ 3767.460110] ata1: hard resetting link
[ 3767.780331] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[ 3769.431289] ata1.00: configured for UDMA/100
[ 3769.431301] ata1: EH complete

EDIT:

This seems to be happening every 600 seconds.

Any ideas what is causing this?

My victim you are meant to be
No, you cannot hide nor flee
You know what I'm looking for
Pleasure your torture, I will endure...
