My new 1tb wd blue is detected as Slave, I connected it to sata no 2 and my old 500gb primary(MASTER AND WINDOWS IS IN IT) to sata no 1. How to solve this?
Entire system in signature
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
