Hello,
I recently bought a 2nd hard drive for my computer. I'm decent at using computers and learning computer terminology bought i'm confused as to why my new hard drive doesn't seem to be detected by my machine and i need to know if this is incompaibility between the hardware or if the new hardware was DOA. I have the HP D4996t with an Asus IPIBL-TX motherboard. According to the HP website, this motherboard has:

Six SATA connectors:
o Supports 1 SATA-150 or SATA-300 disk drive on each SATA connector
o Speed up to 1.5 Gb/sec or 3.0 Gb/sec, complying with SATA 1.0 and SATA 2.0 specifications

NOTE: The faster rate of 3.0 Gb/sec requires that both the hard drive and the motherboard support it. If one or the other does not support 3.0 Gb/sec, the PC negotiates down to the slower 1.5 Gb/sec.

Now my first primary hard drive is a Western digital hard drive which i'm assuming is a SATA 1 drive. The name on the drive is WD3200YS-01PGB0. I believe it is supposed to have 320GB of space. This is where I currently have windows vista ultimate installed.

The new hard drive is a Western Digital Caviar Black WD1001FALS 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s Hard Drive I bought from newegg .com. Now I'm assuming that it should be compatible with my computer as the hp site says that my computer can support both SATA 1 & 2. So when i received my package and plugged in my new hard drive i was disappointed to find that it wasn't being detected by windows vista. I went to Disk Management to see if there was any sign of new hardware being detected but the only thing displayed was my main c: drive. When i would select the option to rescan disks, it would result with no new hardware being deteced. The same thing occurs when I do this from the device manager. All the connections have been double checked and i seem to have everything set up as accurately as possible. But the issue still persists and i have no idea how to fix it.
