I want to use Time Machine on my Mountain Lion. I have 1TB external HDD I use for storing various stuff.
The thing is I selected the drive for Time Machine to work on but nowhere it is mentioned that it will either format the disk or Time Machine will create a separate folder leaving other stuff on the disk untouched. I am bit skeptical that it might erase my disk. I dont want that to happen.
What will happen if I let Time Machine take backups on that disk? Will it erase everything? Can I use that for time machine without erasing the stuff on it?
