Partitioning an "in use" USB HD

I have a USB 500 gig USB Hd,( "L" drive) on which I keep an ATI image of each of my master HD's two partitions, and some other "normal" files, such as a mirror image copy of "My Documents" and my eMail back up. In use about 150 Gig.
I would like to partition it such that I have about 200 Gig for ATI Images, and the other for normal files and copies.
I have the 64 bit Easus Partition Manager.I am not sure how to start the operation - presumably make space? I would prefer not to have to format the HD, but would, reluctantly, do so, case need as I have a slave drive as a cloned back up as well. I would like to end up with "L" 200 Gig and "M" 300 gig.

I Use Acronis Disc Manager 10 it would be easy with that, but no Idea about the one you have got. if you create a Image on the Drive, its easy to then drag things to other partition after. But with Easus Partition Manage I have no Idea as to how secure it would do the Job without loosing anything

Using Easus, click on the L: drive and choose the Resize/Move option. Move the slider down on the GUI until L = 200GB and Unallocated Space = 300GB and click OK. When the process finishes, select the Unallocated Space and click the "Create Partition" option, you will be able to give it the Letter M in that process.

You know the usual warnings, john bunyan. BACKUP before doing it.

Thank you woodchip, and Maj
I will back up - I have my main data partition plus a recent clone of the primary drive, so would not loose anything vital , even with a format.Will mark as resolved.

Happy to help, john bunyan. BTW it can also be done without third-party software, in Vista and W7 Disk Management.

Worked very well! I just find Easus a bit more user frienly eg allocating partition letters.
In another thread I commented that trying to defragment a drive that contains images seems very long winded, as I suspect the defrag is puzzled by a couple if big image files. Now, I can keep the images seperate from day to day ,easy to access, data and back ups.
