I am using the tool Intel Rapid Storage Technology (IRST) v9.6.61001 to display the current status of several disks that are built-in and/or connected to a Lenovo W701 Model 4323. The status window shows disks connected on Port 0, Port 1, Port 2 and Port 5. Port 4 shows empty and Port 3 - well, that one I have never ever seen.

The device-name says that there are 6 ports on the Intel AHCI controller: Intel(R) 5 Series 6 Port SATA AHCI Controller

But the system report says there are only 5 ports. Number of SATA ports: 5

The status windows and the report assigns disks to ports numbered from 0-5. That would result in 6 ports but that is not the case (according to Intel and the report).

So how comes there is a port numbered with 5 (that port corresponds to the eSATA port) even though that port should be numbered as 4 (ports 0 - 4 >> 5 ports).

And where are the connectors for Port 3 and/or Port 4 on that Laptop?

Anybody knows?

I occupied each available port with either a USB- , eSATA or 1394- device, I can access them all and still port 4 remains empty and port 3 remains to not show up at all.

I am puzzled and hope someone can shed light on this.

Lenovo may have chosen not to enable the ports in the chipset if the design of the complete system didn't use them. They also may be enabled but reserved for internal use (for example, on other models with different options). What actual problem are you facing? –  Ƭᴇcʜιᴇ007 May 28 '12 at 1:53
    
@techie007 You certainly got a good point about Lenovo to keep certain ports disabled. I am not facing any hard- or software problem, I want to optimize and to know and understand the internals. –  snahl May 28 '12 at 14:12
