External HD starting twice on boot.

Thu Jun 14, 2018 2:15 am

Hello people from raspberry pi troubleshooting,

I am having a problem with my External HD, which is a Seagate 2 Tb.
The problem occurs when I start the Pi with the HD connected, and the HD spins up during the initial start,
and then it shuts down, to restart again after the big Raspberry logo screen appears.
I was wondering if I could get the HD to start spinning up after the Raspberry logo screen so it doesn't start twice during the boot.

After the boot, it works perfectly so I think it is not a power problem, since the power adapter of the Pi3 can deliver sufficient energy to the HD.

Well for the moment this is it.

Any help would be appreciated.

Daniel.

Rpi3B or RPi3B+?

The 3B needs the OTB to be set to boot from USB, but the 3B+ has it already set, so it might be trying to boot from the USB HDD first.

OTB has nothing to do with it.

I believe it is a "power save" function of the drive that gets "tickled" during startup of the Pi. I have an external drive that does the same thing. I have not seen any issues because of it - as you stated, once all is up and running, it's fine. It's not a full power down, just stops the platter(s) from spinning.

Yes. I think it is just a minor hiccup, but it doesn’t bother much. Anyways, it is left on for 90% of the time, and I never reboot it too much, so nothing to be worrying.

Besides that, thanks for the response and help!!!
I hope I’ll be returning here for more help and understanding of the pi!
