Thanks you for this. I have a 6TB external drive and a 3TB external drive. I don't have room on my iMac hard drive for my complete photo library. What I want to do is to move the iphoto library to the 3TB external drive and use that to work from. I would then back up the 3TB AND my iMac hard drive on the 6TB time machine drive. I am trying to basically find a way of seriously extending my storage capacity without having to spend another 4k+ on a computer with 2TB+ storage.
so can I
move iPhoto library to external hard drive
partition 6TB drive and use half for time machine and half to store an iPhoto library back up?
could I also store other files and folders in the iPhoto partition bit?
I cant link my OneDrive cloud storage to the external drive as it is USB and removable drives aren't supported my OneDrive.
Any help is much appreciated as I am really finding my way here and am not naturally very technologically savvy.
