Every SATA connector? External connectors yes. Internal connectors no. |

Interested readers should be _VERY_ careful about listening to |
| 15 |
previous advice. The major difference between the internal and |
| 16 |
external SATA cables & connectors, a ***particularly*** important part |
| 17 |
of hotplugging, is that the external connector ensures that ground is |
| 18 |
connected before the signals. This ensures that in the case of static |
| 19 |
electricity the drive becomes grounded to the computer which is done |
| 20 |
to eliminate ESD (electro static discharge) events which will damage |
| 21 |
either the drive or the controller. (Depending n which is charged.) |

If you are using an internal power supply and have drive power already |
| 24 |
attached when you hotplug an internal cable then likely you will be |
| 25 |
just fine. |
| 26 |
|
| 27 |
If, on the other hand, you have a SATA drive sitting on a bench using |
| 28 |
a separate power supply then hotplugging with an internal cable is not |
| 29 |
recommended. |

Hope this helps, |
