Unless you copied the files from one place to another, so you may then point your program to the new physical location, I don't think there is anything you may do
That is what I was afraid of. I did not save it to my MAC yet and then the external hard drive was dropped. Thank you for responding.
For anything important, buy TWO external drives and copy files from main drive to backup drive
Easy with a Windows computer with more than one USB port, should be easy with a Mac as long as you have 2 external connections
It had 4 years of photos and videos on it.
To what did your camera record those photos and videos - camera's internal memory, inserted memory card, other?
Any remote chance that the latter may still exist for you to use to download the camera files to your new external hard drive?
