[Odroid HC4] HDD immediately shuts down after use

Hello everyone,

I recently bought an Odroid HC4 to replace my NAS, Raspberry Pi 3 and NVIDIA Shield TV.

I’ve installed an HDD (Samsung HD204UI) and was able to copy everything over from my NAS. But the issue is that as soon as a write or read operation finishes, the HDD spins down. So when I open dietpi-drive_manager, it spins up, only to spin down a second later. When I start a benchmark, it spins up again and stays that way until the benchmark is over. Immediately after it spins down again.

In the dietpi-drive_manager, I’ve set the spindown time to 30 minutes. Seems like the HDD doesn’t care about that.

I’ve run smartctl, which reports:

SMART overall-health self-assessment test result: PASSED

So yes, the drive is old, but is that already the reason why it immediately shuts down? Doesn’t really make sense to me.

Thanks for your help!
