Hi Stephen, Just a thought... " "The disk you inserted was not readable by this computer." I read somewhere about this happening to a guy and he finally worked out while it happened and was able to correct it. I kept a note about it... The solution to this person's encrypted drive not readable in El Capitan was:
/Begin Quote: "I just figured my issue out, my 5TB drive was in process of being encrypted when I updated to El Capitan, and that was the reason why I couldn't use it. I plugged it into my mac running older version of OS and allowed it to finish the encryption. Once that was done I was able to use the drive on El Capitan" /End Quote: Cheers, Ronni Sent from Ronni's iPad4 > On 6 May 2016, at 3:52 PM, Stephen Chape <chap...@bigpond.com> wrote: > > Hi Peter and thank you. > He needs to encrypt the HD’s because he is an Emirates Captain and sometimes > carries one of them with him to different countries around the world.
