What kind of HD do I need for replacement?
I need help and tips on changing my HD in my iMac. My hard drive has been failing since I've been getting slow startups and shutdowns, tried a disk utility repair and did a clean install of the OS and I still get a slow imac and the spinning rainbow a lot.
I just wanted to know if the HD I need to buy is a regular 3.5 SATA 500gb HD for replacement? Does it need to be a SATA 2 or a SATA 3? I don't really know if there's a difference or if I will encounter any compatibility issues if I replace my HD with a SATA 3 since it's the one usually available here in my country(Philipp
Any help would be appreciated. Thank you so much!
Before spending any money, try re-formating the hard drive using the "write zero" option to map out any bad blocks. Then give it one partition, this will ensure it's set to GUID. The new hard drive may need to be jumpered down to 1.5 GB speed to be seen by your machine so make sure the new drive can be slowed down. These setting can be fund on most drives by doing a web search for the name of your drive and jumpers. Here's the one on Western Digital SATA II drives: http://wdc.custhelp.com/app/answers/deta...
