Deleting Partitions on a SSD
I have a SSD which I partitioned into three sections. I am now wanting to take out the partitions. I have deleted all the information from the three sections. I have used Disk Utility to erase all three sections. Each section still shows some MB of information, however when I open them on the computer nothing shows up.
What I am now trying to accomplish is to remove the partitions so I am back to one single storage unit. When I am in Disk Utility I am unable to click on the partition button, it is grayed out. When I put the mouse over the button it says Disks with master boot partition maps cannot be partitioned.
How do I remove the partitions?
