Hi all,
I`ve read lot of topics here and there, and i`m still not able to make my hdd go sleep/standby. I have two disks in my NAS build. One of them is 128GB SSD, where i`ve installed DSM at the begining and i`m using it as Volume1 (every package is installed there). Then i`ve connected second disk (1TB HDD) and i`ve created Volume2, which i`m using as storage for my music/movies/photos. I`m aware of that DSM is installing itself on every connected disk to machine. I`m accessing Volume2 occasionally, but HDD is never sleeping, it is always active/idle. I`ve tried to change disk settings using hdparm but i can`t see no difference. When I try to use "hdparm -Y /dev/sdc" command, disk is waking up after few seconds. Additionaly when i use dstat to track disk IO i can see that every 60 seconds (or something like that) some process is writing 4096b to disk. Do you have any ideas what is the problem?
