iMac 27" HD upgrade
I know you have to use the same brand HD because of different internal temperature sensor interface, which controls cooling and fan speed.
Mine is a seagate, and you do not have the 2TB disk available.
If you use a new, for different brand, temperature sensor cable (see: http://www.shopwiki.com/iMac+Hard+Drive+...
bottom part), could you use a different brand HD?
Is the MB end of the cable the same on all brands of HD?
Is the HD brand somehow "embedded" in the imac firmware or bios?Thanks
