Can't erase to format EasyStore for MAC

I just hooked up my EasyStore tonight. The computer (El Capitan OS) recognizes the drive, but it is read-only. The instructions indicate that I need to format it for MAC by erasing, using DisK Utility. When I try that, it gives the message that “erase process has failed.” What can I do to start using my new drive?

Hello davidigor,

What is the files system you are in selecting in Disk utility to format the drive?

Have you tried disconnecting the drive>> restating your Mac system>> Plug in the drive again and format?

I am having the same issue. I’ve tried: disconnecting the drive>> restating your Mac system>> Plug in the drive again and format, but it still does not work. Can anyone help, please? Thanks!
