I was searching for a TB hard drive and happened to system info profile my current drives to see what model I had specifically. Then I noticed when I pulled up the model number it says it is a WD Caviar Blue drive, not a Black drive. Could the Mac system profiler be wrong? Or is it the wrong drive? The model number should be WD10000LSRTL but the mac says it is WD10EALS. I bought a boxed version from Best Buy and I am comparing the serial number to the box to the serial number on the profiler so I know I am looking at the right thing. I attached the profile info and the registration info I just got when I registered it. Am I going crazy? It just doesn't seem right.
