When I try to check Read/Write speeds on my new MyBook Duo, it give me an error message “Speed test can not be run on selected location because it is Read only”.
How do I change it to Read/Write?
I would like to know what kind of read/write speeds I am getting with this external hard drive.
I have an iMac and have it as RAID1. I am using it primarily for all my Photography files for Lightroom and Photoshop; as well as backup, timemachine, store movies, etc.
