My iMac's internal drive recently died (the second one, the first was under warranty) so I purchased a Seagate 1TB external drive from Walmart to get it back up and running. To make a long story short, it will not boot my iMac. After discussions with Apple (they even sent me a Leopard disc to install before upgrading to Snow Leopard thinking it was a firmware thing) we have concluded that my iMac can't boot from the Seagate drive. I get the kernel panic foreign language grey screen. After research I was led to OCW and after calling them I was recommended this - http://eshop.macsales.com/item/NewerTech/MSQ7500GB16/ - as a drive to boot my iMac. My question is does anybody have experience with my situation and how did you resolve it? Has anyone had experience with the NewerTech drive and was it favorable? Thanks for any input.
