I'm not a computer hardware wiz, so please bear with me. I bought a new 7200 rpm WD black hard drive to replace the primary drive in my G75. I opened up the casing, put it in the second bay (left one), and closed it up, thinking that was all I had to do to use my new drive. When I open up My Computer or Disk Management, the new drive isn't there. I opened up the BIOS and under boot devices it appears as "P1 WD7500BPKX" Do I need to download a driver or something for it to work??
