I recently had a problem with My Passport and had to buy a new one. I have plugged it in and reformatted it and now Time Machine won't recognize it even though it shows on my desktop and the disk utility doesn't see any problem. Any ideas?
Did you choose HFS+ as file system for the external hard drive?
I reformatted and used Mac OS Extended (Journaled).
Disable Time Machine from System Preferences.
Choose Select disk button, remove the old TM backup disk and add the new one.
Oh so easy! Thank you so much
