Time Machine deleted data off external hard drive
Apple support was not able to solve my issue:
I attempted to add an external hard drive (with files already on it) to back up my computer using time machine.
When prompted to add the disk to time machine, I selected yes.
Then, time machine began to delete all the existing data off the hard drive. There was NO prompt to accept this. I was also not able to cancel.
This is a serious issue. Beware.
Don't use time machine, just backup your information as needed.
