How-to disable HDD suspend

as many of us know, Vero4k will suspend/power down external HDD connected via USB after some amount of time.

Does anyone know how to set up this time amount, or, even better, cancel this suspend of HDD? So it will spin forever until disconnected from USB.


Currently, spin down is provided by the hdparm package. In the future, we will likely change this to hd-idle.

You should be able to configure things via /etc/hdparm.conf


Thanks very much :slight_smile:

Trying hdparm to show me APM setting, so I can disable spin down and let it run indefinitely. But it giving me errors like:

hdparm -B /dev/sda1
HDIO_DRIVE_CMD(identify) failed: Inappropriate ioctl for device

…it means that its not compatible with my HDD?

That may mean that it won’t spin down – as the caddy doesn’t support this. So you may not need to do anything.

Spin down is working. I have observed and heard it to spin up every time after not using Vero4k for few hours. Its a 500GB WD Blue HDD in SATA-USB 3.0 enclosure. Maybe the SATA-USB converter preventing hdparm, I dont know. I will rather not mess with it :slight_smile: Anyway, thank you for support.
