The thing is that on most file systems there is an inode for every 2K or every 4K. So, if you've filled your disk with 1K files (each of them needs it's own inode) and you have 1 inode every 2K then it would be safe to assume that you'll run out of inodes when filling half the disk. As far as I know, the only thing you can do is change your filesystem to use more inodes. I remember that I had a linux system once, set to 1 inode/512bytes or 1 inode/1K and I doubt that you can further reduce that.
