Um, no. PlusOptimizer is an HFS+ formatter that doesn't actually loose your data.
Here, an excerpt from the read me of PlusOptimizer: Optimizing Your Startup Disk Your startup disk is the disk containing the current System Folder. Since the open system files on the disk containing the current System Folder cannot be defragmented, you need to start up from another disk to defragment these files and completely optimize the disk. If you do not have another hard disk with a System Folder, you can startup from your Mac OS system CD. To optimize Mac OS Extended (HFS Plus) disks, the Mac OS system CD must be Mac OS 8.1 or higher. snip Directory Damage PlusOptimizer performs an examination of the disk directory data structures on which it relies. If PlusOptimizer finds that your hard disk directory is damaged, try running Disk First Aid (supplied with your computer) to see if it can repair the damage. Because Disk First Aid does not check for every type of directory damage that PlusOptimizer checks for, it is possible that Disk First Aid will not be able to confirm the damage. PlusOptimizer may be unable to optimize your disk until the damage is repaired. If necessary, use Alsoft's DiskWarrior to repair the directory damage.
