I have a 1000G external hard disk formatted with Mac OS plus. It is a Omega drive, which came by default with that format. Now I have 200G free space and would like to reformat this free space to NTFS. Is it possible to resize the partition without losing the 800G data?

You can use
/Applications/Utilities/Disk Utility.app
for that. It allows non-destructive resizing of partitions. See for example this article on how to do this. Alternatively, you can use thediskutil
command line tool, see here.Although it's possible to resize without data loss, you should always have a backup at least of your more important data on that disk. Power outages and system crashes while reformatting a disk aren't fun.
Once your HFS+ partition's size is reduced, you can create a new partition in the empty space (though you cannot create NTFS partitions from OS X).
