    i hope this wasn't a duplicate thread, i did my due diligence of searching the forum prior to posting.

    do i have to use an external drive that's solely to be used for a time machine back up? i have a 1 tb drive, but it has all sorts of other files on it and i would hate to have to use it only for a time machine back up (as i have a new macbook air, and 1 tb is a lot to waste on a time machine)


    thanks!

    You can use it for other data as well. TM requires you to use HFS+ so if it's in another format, you will have to create a new partition or reformat the whole drive.

    Yeah. Just go to System Preferences > Time Machine and select your external HD.

    that's what i thought, but so it's not going to "wipe" my external and then put on the backup for time machine? i guess that's what i'm terrified of :/

    No, as it is in the correct format. It will just create a folder for the backups.
