Hi,
For a couple of days I am running an Orange Pi Zero Plus (OPI0+) together with an external USB 2.0 HDD (Western Digital) as a mini NAS. I installed an OMV ISO image based on Armbian.
The HDD has a separate power adapter, independent from the OPI0+. The OPI0+ has very little power consumption, particularly in idle. The power cable/adapter of the Western Digital HDD is plugged into a remote Wi-Fi (WLAN) power plug, which can be turned off and on - from almost everywhere.
Would it be okay to turn off the HDD power, means to turn off only the HDD, when I don't use the NAS?
Remarks: I will use the HDD very rarely. The power consumption of the HDD is much higher than the OPI0+. An OPI0+ shut down, via OMV, causes a permanent shut down. It keeps on being off, even after turning on the power plug, means it doesn't boot. It boots only, if I remove the micro-USB cable/adapter at the OPI0+ and plug it in again.
Thanks for your advise,
Joe
