28 No, I totally believe you, but that's not the issue.
29
30 The connectors on the motherboard are ALWAYS internal connectors so
31 that you can use all of them with internal disk drives, etc. using
32 internal cables.
33
34 The eSATA connector is, however, different. You can see it in the link
35 I sent earlier, copied here:

37 http://www.serialata.org/technology/esata.asp
38
39 There is a _special_ SATA-to-eSATA assembly to make the conversion. If
40 your case has a cable built into the case and already hooked up to the
41 eSATA connector then it will have an internal SATA connector on the
42 cable. However if you look at the eSATA connector itself, on the
43 outside of the case, it will look like the one in the picture on the
44 above link. More below...

66 Your cables are perfect for internal drives. Keep in mind that the
67 internal connectors are only spec'ed for 50 insertions in their
68 lifetime. They aren't made to be messed with very much. eSATA
69 connectors are spec'ed for (IIRC) 6000 insertions.
70
71 Here is an example of an eSATA bracket if your motherboard or case
72 didn't come with one. It has an internal SATA connector on one end
73 which you plug into your motherboard. It has an eSATA connector on the
74 bracket.

77
78 That one would use a back panel slot but essentially steals a PCI slot.
79
80 Again, I think you've done everything perfectly as far as I can tell.
81 I only got involved in the thread at all because (IMO) incorrect info
82 was being tossed around about eSATA, SATA and hotplugging. If you're
83 not going to use eSATA then none of this matters to you today. In my
84 case I had to learn this because not all internal SATA ports on my
85 Intel MB were eSATA compatible and I needed to do it the right way.
86
87 Cheers buddy,
