OS Drive and SATA Question

by wildbird / August 12, 2015 5:43 AM PDT

I have a question about to choose a right SATA for OS Drive. I am not an expert but I love to build and assemble PC, sorry for these silly question.

Many years I have been using my assembled desktop pc without problems but it was a bit noisy I think it could be because of my 5 drives and 1 OS drive. Sometimes I blamed to the Crosair H80 CPU heatsink and Thermaltake Level 11 Case. Only this month I found that I was wrong. How it was happening is funny and a shameful experience.

My OS was Windows 7 Ultimate I am allowed to upgrade to Windows 10 for free. So I upgraded and having problems of Outlook 2007. To find the cause of the problems I uninstalled and reinstalled the OS many times.

My Motherboard is Rampage III Extreme, the CPU is Intel i7 950 @3.07GHz and had 6.00 GB of RAM. About two months ago, I replaced the OS drive Croair SSD to Samsung SSD 850 Pro. I got Samsung Megician software I have not used it a lot. This time I use and test the performance of the drives and I found that same HDD has different performance according to the SATAs. 3 of the SATAs my motherboard has cannot installed the OS (AHCI mode is ON) but IDE mode is OK. I checked and tested repeatedly and finally found the right SATA for the OS. Now the computer is not noisy and it is faster than before.

My request here is to get some useful links or books’ names and your educational explanation for assembling PC.

Hmm, "right SATA"?

I always used the lowest numbered SATA port for the OS or boot drive of the OS or rather boot manager. Now while there are RAID setups that would be specific to the RAID implementation and would not be found in a book on PCs in general.

Why a book for what I found to be a simple thing? That is, the lowest number port.

SATA Port6 [Not Detected]

Thank you, your answer is what I was looking for. It is a good lesson for me.

I found the Port numbers. I am lucky the OS or boot drive is on the lowest port number the port 1.

My motherboard has 6 drives:
Hard Disk Drives
1st Drive [HDD: P0-Samsung SSD]
2nd Drive [IDE: S0 SAMSUNG HD1]
3rd Drive [IDE: S1 Hitachi HDS]
4th Drive [HDD: P1-SAMSUNG HD1]
5th Drive [HDD: P2-Corsair CSS]
6th Drive [HDD: P4: WDC WD20EAR]

All these above drives see in the BIOS but in AHCI Settings SATA Port 6 is not detected.

AHCI Settings

AHCI CD/DVD Boot Time Out [35]

*SATA Port 1 [Hard Disk]
*SATA Port 3 [Hard Disk]
*SATA Port 4 [Hard Disk]
*SATA Port 5 [Hard Disk]
*SATA Port 6 [Not Detected]

Motherboard has 3 particular SATA connectors. 2 Connectors are Marvell Serial ATA 6.0Gb/s Connectors (7-pin SATA-6G-1/2 [red]) and 1 JMicron JMB363 Serial ATA connector (7-pin SATA_E1 [black]) I do not know the reason port 6 is not detected or is it normal but I think may be related above these 3 connectors. If you have any idea about this please explain to me.

Next time if I assemble a new computer I will remember to select the lowest port number for Boot or OS Drive.

Thank you all

*Thermaltake Level 10

SATA Port 6 [Not Detected]
by wildbird / August 17, 2015 4:05 AM PDT

I have read the motherboard manual again SATA 1-6 they are ports but Marvell Serial ATA 6.0Gb/s two connectors are not recognized as Port. I have installed two Drives but they are not appeared in the BIOS ports information. Windows cannot boot from these Marvell Serial ATA drive too. Out of SATA 1-6 Ports I used only 5 Ports. Now I found that why the SATA Port 6 is not detected.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
