I am useing wd my book essential with my Mac mini
I would
like to have the wd 2TB as my main back up disk mainly for
films
I download the files/films on the 500GB hard drive of the
Mac mini and use time machine to automatically back up to the
wd disk so when my Mac hd is almost full I can delete files on
the Mac hd knowing they are safely stored on the wd disk.
But when I delete files on the Mac they also get deleted from
the external wd disk only had my book essential for almost a
week can anybody advise me on where I may be going
wrong?
