HDD fan stuck on full blast after HDD replacement
I followed the instructions to replace the 320GB Hitachi hard drive with 1 TB Western Digital - and it worked great.
Unfortunately, after starting up the early 2008 iMac, the HDD is going full speed.
The temperature on the HDD reads - 33C - which seems quite normal. I have tried to reset the SMC controls, rebooting many times and I was unable to run the Apple Hardware Test. (I upgraded my machine to Lion and I can't get the AHt to run).
I saw the HDD Fan control program - which looks like it was setup for the 2011 HDD problems. I'm not sure I want a software program for this.
Any suggestions to reduce the HDD fan or other checks?
