Hi all, thanks for any responses in advance.
I have a 1 TB external hard drive that I need to be able to use on both Mac and PC computers. Additionally, I need to be able to encrypt it with a password. The issue that I'm having is combining these two needs. Currently I have the drive formatted to exFAT (to use on both operating systems) but I am unable to encrypt using Disk Utility, as I get the message "A GUID Partition Table (GPT) partitioning scheme is required."
When I try to repartition, I get "You can't resize the partitions on this disk because it uses the Master Boot Partition scheme."
How can I get past this? Ideally, I would not like to download any additional software and use Disk Utility, but I don't know how to get past the error messages.
There is nothing on the drive I need so I am prepared to wipe the HD if required.
