I have a Raspberry Pi 3 configured to boot from ssd drive and it works great and fast, until I attach any other drives (planning on using it as a media server). Once I attach any other drive it stops booting. It powers up but that's it. No output to screen, but all drives spin up and ssd boot drive also powers up.
I have 2 powered hard drives that work fine on another Pi 3 that is running from a micro sd.
I've tried running the drives through a powered hub and it made no difference.
If I attach the media drives after it boots everything is fine. I thought if I could delay the power up on the other usb drives maybe that would solve it, but I don't know if that's possible.
Any suggestions would be great.
