If a sector is bad on the drive, a program like Drive 10 can map out that sector so that the operating system doesn't see it. You would then be able to use the drive.

Actually, when you initialize a disk on a Macintosh, it's only formatting the catalog. When you 'Zero all data, it erases everything from block 0 to xxx,xxx,xxx hence it takes forever! You should try it on a 500Gb Raid! Man, i leave the machine for a week and it's just about finished.
If you have warranty, just return the machines to apple, they'll fix it and maybe replace your drive. Has been know to happen, especially when they have a faulty batch of drives. Manufactures only test the first Drive in every 10,000 or something stupid.
