Can't Departion disk—Lost 500 GB in storage
So I was playing around with partitions on my external hard drive because I had planned on using bootcamp, and it required me to have a flashdrive with >5GB which I didn't have. So now it is looking like half of my drive is available and the other half is referred to as "free space." I have tried to add a journaled mac partition but it won't execute the task, even though I can make the screen look like it is about to do it. How can I get my memory back?
