No I am not using SATAs, yes it does have SATAs, I am using the Promise PRI Raid controller on board, not for RAID arrays (Striping or Mirror) just to use another hdd as an additional storage device.
And trust me, I searched before I posted here and read everything i could find, everyone was talking about setting up arrays which i do not need for now.
As a matter of fact, the pins on the WD hdd are(were) set to master. But, what i discovered was that it needs to be set to Cable Select. I rebooted, went to Ctrl+F, Auto Config, it set it to default Array 1, Performance (Stripe), etc. nothing. I was out of my mind by then, and rebooted again, i missed the control F twice as my children decided to interrupt me several times, and after i rebooted 3 times (by accident) it finally recognized the hdd. Figure that one out.
Thanks for your attempt to help.
