the SATA connectors on the motherboard are colored ORANGE for three and BLACK for one. What does the color coding mean? Is the black a higher speed connector, or lower speed? Is it reserved for the DVD drive, or for the primary Hard drive?

The one that's different is eSATA, probably. Have you looked it up in the Hardware Maintenance Manual for your specific system?

It doesn't even say in the manual that there is a different color coded sata on the mainboard. what is eSata? What would be different about eSata versus the others?

I looked up eSata and it says it has a different size connector, but the connector for this black connection is the same shape - L shaped... but I think it definitely must have some different qualities. **bleep** is the ThinkCentre M series specifically the Lenovo ThinkCentre M57p (9088-BGU). It should have some simple explanation which should have been in the manual but was not...

Awesome, thanks so much. when I searched for significance, it says that the only thing it really offers is longer distance for cable, but it was not a faster connection. But on the chance it is better, should I attach the main hard drive to it? thanks for finding this for me...

One more question. This is meant to connect to an external device, so it is meant for a longer length of cable. I imagine it has the L shaped connector so alternatively someone could plug an additional sata internal drive, but with no special benefit. My one question is do these four sata drives work in a hierarchical order, so that the external one mounts after the first three, in sequence, so in theory it should be used for the last drive? I hooked the DVD to it, and it appears to work as the "D" drive but was wondering if that is NOT a good use? maybe these are silly questions...

thanks again. I want to clone a hard drive, so need to free up two drive ports to do this. Now running into problems of signature collisions - <sigh> I am just innocently trying to have a back up hard drive in case one fails, and MS makes doing this so difficult. Guess I might just go back to an XP version and see if I can clone using that system for windows 7 hard drives as it worked for window vista, but there appears to be a way around this problem of using a windows 7 system to clone a windows 7 disk... hoping that it will work for a windows 8 disk cloning as we now have one of those to worry about. Again, only doing this to make sure we can survive a hard disk crash which Microsoft makes so difficult. Their disk backup tools DO NOT reliably work. Again, thanks so much...
