The SATA spec allows for hot plugging, so technically yes, but it also |
48 |
assumes the drives are in some sort of container so that power and |
49 |
signals are applied at the right time. |

The plug on the front of your case is probably eSATA which looks |
52 |
similar but has some small changes. What you want to do is figure out |
53 |
which of your MB SATA ports are eSATA compatible and then run one of |
54 |
those channels to the connector at the front inside your case. |
55 |
Typically SATA drives are converted to eSATA external drives by |
56 |
putting them in a case you can get at most computer shops for < $30 or |
57 |
so. |
