New HDD detected as Slave

Solution
Oh - your sata controller is configured into IDE mode. That's why it shows that.
Normally is should be in AHCI mode.

Anyway - if windows is already installed, then just forget about it and leave it be.


I'm not understanding the issue here. The computer works correctly? it boots fine and everything is accessible? Were you wanting the new 1TB HDD to be your boot drive?

As already stated, PATA/EIDE/IDE has master/slave attributes. SATA does not.

What you probably see is a listing of attached drives ORDERED BY which SATA connection they use
 


This is what is shown in Post screen of PC.

IDE CHANNEL 0 MASTER : NONE
IDE CHANNEL 0 SLAVE : NONE
IDE CHANNEL 1 MASTER: HL-DT-ST DVDRAM DRIVE
IDE CHANNEL 1 SLAVE : NONE


IDE CHANNEL 2 MASTER: NONE
IDE CHANNEL 2 SLAVE : WD10EZEX WD BLUE 1TB
IDE CHANNEL 3 MASTER: WD BLACK 500GB
IDE CHANNEL 3 SLAVE : NONE
 


Agreed. If it isn't acting like its broken, don't fix it (where you're guaranteed to break it and require a reformat and re-install of everything.)
 


Oh, that maybe. Cant it be changed to AHCI after windows installation?
 


It changes how the data is accessed. The different modes are not compatible with each other.
 


Solved it. Now HDD is detected as SCSI 0 and SCSI 1. And doesnt show as IDE
 


I did that onlty, changed registry values from 3 to 0 on the respective fields and changed bios to AHCI from port 0 to 3 and IDE from port 4 to 5
