time machine on mac

hey there i have never used time machine before because it keeps saying i need to format my external drive and it will only work on a mac alone and to me that is wasting a 1 Tb hard drive

is there some way for me to use a tb hard drive with Time Machine that it would be able to back up my mac plus also be able to work on a mac and pc???

by the way i have a few stuff on the Tb but not much at the moment.....

You could try partitioning the drive. Make one partition a Mac partition for Time Machine and the other a PC partition.

You will have to back up the drive first, because partitioning will erase it.

No.

Time Machine is only Mac supported.

Time Machine used on Mac only supports Mac.

You need to partition your hard drive as I suggested in my previous comment:

I think you keep misinterpreted me

I don't want to use time machine on a pc but I want to use it on 1 Mac partition and the other partition I want to be able to use it on a pc or Mac if i want to copy stuff from a pc or Mac to it

Split the external drive into two partitions using Disk Utility. Make one partition Mac Extended Format (Journalled) to use with Time Machine, and make the other partition ExFat to use with Mac and PC for storage.

This link will explain the advantages of ExFat:  http://www.tech-recipes.com/rx/2801/exfat_versus_fat32_versus_ntfs/

Note though, that it is only supported on the PC side for Vista and newer. It won't work with Windows XP, for instance.
