Thanks for the swap idea but I will be following the instructions that Brad Struges posted online to convert to an iMaCC.

Thanks Netfreak and System7 but I had beaten you to the suggestion. No luck. Boots up fine but no HD and I hear it spin up but then slows down and stops. Also tried the command option P R to zap the pram but no success.
Again thanks for the suggestions.
Color Classic2009 I'm curious as to what results you found on your Color Classic as mine has the same symptoms and I did determine it was the hard drive. [:D] ]'> Rather then try and find a replacement I'm in the process of getting an Imac motherboard into mine and don't worry everyone...
