I have a Western Digital 6TB external hard drive that i use for TimMachine. I was wondering if it's possible to password protect this drive, so that if it fell into the wrong hands, a password would be required to access the files in the backup? Also, is it possible to password protect the internal drives in my MacPro, so that if it was stolen, the drives could not be removed from my password protected MacPro and put into another computer to access the files there? Sorry if this is a dumb question but i cant seem to find any info on this on the web. Thanks.
