No option to erase or partition Samsung 850 SSD for MacBook Pro
I trawled the internet to find a solution as to why my MacBook was freezing and after days of attempts I came to the conclusion that the HD needed replacing. Now I've replaced the HD with this new highly recommended SSD from Samsung, I can't erase the drive and I have no option in Disk Utility to partition it either. I try to erase and the machine tells me the process has failed. I've tried booting off a USB and I get the same result. It's driving me nuts. I need help. Thanks in advance.
MacBook Pro, iOS 8.0.2
