missing disk utility?

i've got an old powermac that i have installed a few large hard drives in. i got the pci card to let you do it some time ago. i just installed a hard drive, but found that i had partitioned it sometime ago when i was still using windows. i went to go to disk utility to format the disk, but oddly enough, disk utility is not in my utilities folder. this is an install of tiger.

i have no idea why there is not a copy of disk utility on this computer. does anyone know how i can get it? i got the computer off of ebay, so tehre were no install disks.

 

well, i don't have install disks, didn't come with the computer. do you think someone with a ppc edition of tiger could send it to me through email, then i just drag it to utilities? would that be a possibility?
