I'd suggest moving the data to another drive and then partitioning your 500GB drive. When finished, move your data back to partition 1 and set up Time Machine on partition 2. Sizes will vary based upon your HD and your stuff.

Just make sure you choose "Mac Os Extended (journaled)" when you initialize your drive. Partitioning is an option, but is not necessary if you have enough contiguous space on it to back up your main drive.

A PC? Are you one of those people who are installing Leopard illegally on a non- Mac machine. This is Blasphemy!
The God-of-All-Macs must be really pissed off by now!
i'm confused. Really. I thought it was your external drive that had stuff on it you wanted to preserve? It would help to use punctuation. But, yes, the point is to empty your external drive, erase it, format it and still have enough room to use it to back up your time machine after putting the stuff back on it. A simple Mac task. But maybe I misunderstood. The PC thing got me confused.

you missunderstood...i have the external with about 190gigs of stuff then a pc with 200 gigs free space so i want to dump the external onto the pc then dump it back to the external once formatted but i don't think it would be able to since they are different formats you know

I think I still misunderstand.
1. You have a computer with Leopard on it, and 200gigs of free space. What kind of computer is it? If it is a Mac that you call a PC, than it's OK, just a weird choice of letters.

2. You have an external drive with 190 gigs of stuff and it's not properly formatted

3. U transfer your external drive stuff to your computer with 10 gigs to spare

4. You format your Ext HD with you computer (Mac extended journaled)

5. Now your computer sees a lovely virgin drive properly formatted and it's happy

6. U transfer the 190 gigs back on the ext drive.

7. U get rid of the same 190 gigs on your computer.

8. Now u all set to go to use your time machine. You have 310 gigs available on the external drive to back up the 200 gigs from your computer.

Of course, this is all assuming your computer is a Mac running Leopard, not just alien computer in Mac clothing.

I don't know that I know the answer to that one! Is the external drive Mac or PC formatted at this point? If it is PC formatted, then if you connect it to the PC, there shouldn't be any problem transferring all the files to it.
You can then connect it to the MBP and initialize it. You can then create 2 partitions with the Disk utility, one that's formatted for the Mac, the other one for the PC. When you reconnect to the PC, you should be able to transfer the PC stuff back on the PC-formatted part and have the other partition available for the Time Machine. I've never tried that one, but I don't see why it shouldn't be feasible.

160gb on the mbp
If you're going to get it almost full, you'll need MORE than 160 GB to back it up since each time it gets backed up (every hour, every day...depending on what you decide), a little bit more info will be added to the previous back-up. I'd give it at least 200 GB.

You'll need a utility to allow PC to read Mac

Unless I'm mistaken PC can't read/write Mac formated drive without a utility to enable this and for Time Machine to work the drive must be Mac formated?

So unless you copy via a network (which can be tricky) find yourself a copy of MacDrive-7 and then you can copy directly to drive in Mac format.

Right, but the Mac can PC-format the HD without extra software and then the PC can read it. No need for complicated network transfer.
