no, it has to be on another hard drive or on a partition of another hard drive. it will format the drive before the first backup.
 
yep. sorry didnt make that clear. but its recommended to be on another drive because if that drive dies your backup dies too.
 
A backup on a different partitian on the same drive would be pointless. If the drive fails or gets stolen the backup also fails or gets stolen.

Unless you often delete files you need its pointless.

Best thing to do is use an external drive.
 
can TMachine make backups in a folder in my primary HD?
Why would you want to do this, since one of the primary reasons for a backup is in the event the primary (internal) HD fails? If it fails, you would lose both your drive and the backup. Not the best solution.
