[Trouble]
HDD won't start running from default SATA power port

I can't power up my Hitachi 500GB HDD with the 5V output. I can hear it trying to start but no luck.
Error log:
tail -f /var/log/messages
kernel: [ 2784.458100] ata1: hard resetting link
kernel: [ 2786.815591] ata1: reset failed (errno=-32), retrying in 8 secs
Any help? |

Okay, problem solved. I was using a 5V - 700mA phone charger which obviously wasn't enough to power up the HDD so I changed for a 5V - 2A and that one is powering everything great!
Thanks |

Hi,
What HDD are you using?
And what charger?
I have a 2.1A charger and the 1TB Hitachi and I have the same errors in the log.
Also, I am running Bananian 15.01. |

If your drive won't spin up with 2.1A, I would not try with a larger charger : you may burn the very tiny slope on the bPI mother board.
I suggest to power your disk externally. |

Yes, I did that eventually. |

You should keep in mind that using the wrong USB cable between PSU and BPi the voltage might drop substantially: http://forum.lemaker.org/forum.php?mod=viewthread&tid=8312
Regarding current: The Micro-USB connector is specified for 1.8A max. and the PMU has protection mechanisms. You should check current/voltage as outlined in this thread. |

If you have a look on bPI's schema (and I guess it's the same on bPro), the SATA power connector doesn't pass thru the PMU : it's why you can power the board using this connector  |

That's right. The sata power just connects to the DC-IN. |

i was having the same issue. moving to a shorter cable made it so that a platter hard drive (500g/7200rpm) would power up and be stable. my OCZ SSD's however are still having the same issues.
