You have 2 systems. It works in one motherboard and it doesn't in the other one. What model are the motherboards? I'm not trying to convince you that there is an incompatibility issue, but that most likely is the case unless the SATA ports are not working on that motherboard. I presume that you've already determined that SATA drives work properly on that motherboard?
I plugged the converter (sata cable) in the sata port where my old HDD was (it still is and works fine). So i guess the problem is caused by another hardware....if you don't have anything else on me...
It's because a new drive costs much more than 20$ here in my country, plus i got the adapter already, so I just wanted to know if there's anything that could solve the problem.
Thanks though! I appreciate it
