Hi there, I'm trying to change my hard drive to solid state. I purchased a Samsung 250g SSD and a 2.5" SATA External Case with USB 2.0. I connected the SSD to the SATA external case and then connected to my MacBook (Model identifier: 3,1) with a USB. I can't see the SSD in my Disk Utilities, so cannot format it to begin the carbon copy transfer. Can anyone suggest a solution? Once I've used Carbon Copy to transfer the contents of my existing HDD to SSD I'll put the SSD into my MacBook permanently. I just need to be able to see it and format it first!!! Any help would be great! Thanks!
