bad blocks on 250GB G5 drive

I am the law!
I've experienced file system corruption twice on my G5 so far (I've had it since the beginning of November)

I finally got tech tool pro and I'm running a surface scan on the drive as I write this. So far its found 15 bad blocks (its about 1/4th of the way done). In the TTP documentation it says

bad blocks are areas of media that cannot store data reliably. All hard disks have a few bad blocks when they are created. These are “mapped-out” by the manufacturer at the factory or when a drive is reinitialized using the “zero all data” option. Mapping out bad blocks stores their location in a “bad block table.” Once a bad block is mapped out, data is no longer written to that defective area of the disk. Occasionally a good block will go bad. If this occurs in a block storing a file, the file may be corrupted.

...

You would typically use Apple’s Disk Utility or Drive Setup to reinitialize your drive. Be sure to choose the option to “zero all data.” This may take several hours (depending on the size of your drive). It will test for and attempt to lock out any bad blocks that are found anywhere on the disk surface. If the re-initialization is successful then the drive should be fine at that point.

So should I get the drive replaced or should I just reinitialize it and write all zeros to it?
