____________________________________________________________You can download factory diagnostic disks for just about any hardrive in existence by going straight to the maker of the hardrive, or through links provided in the Utilities section at http://www.bootdisk.com, and most all have the ability to wipe the entire drive clean, or LLF the drive, or write disk pack the drive, which all accomplish the same thing, which is to completely remove the prioritary info, I know because I've done it many times.

I am sorry to contradict with ur theory. Yes! Zero-Filling does the job of wiping the hard drive but still Zero-Filling and Low Level Format are two entirely different things.
In LLF the u make the hard drive empty (filling a hard drive with 0's doesn't nake it empty. It makes the hard drive full of 0's). I still stick to the same argument that Zero-Filling is not LLF.
Just because everybody makes the mistake of calling Zero-Flilling LLF, it doesn't mean u should too.
Why don't you read the following.
"Low-level formatting is the process of outlining the positions of the tracks and sectors on the hard disk, and writing the control structures that define where the tracks and sectors are. This is often called a "true" formatting operation, because it really creates the physical format that defines where the data is stored on the disk. The first time that a low-level format ("LLF") is performed on a hard disk, the disk's platters start out empty. That's the last time the platters will be empty for the life of the drive. If an LLF is done on a disk with data on it already, the data is permanently erased (save heroic data recovery measures which are sometimes possible).
If you've explored other areas of this material describing hard disks, you have learned that modern hard disks are much more precisely designed and built, and much more complicated than older disks. Older disks had the same number of sectors per track, and did not use dedicated controllers. It was necessary for the external controller to do the low-level format, and quite easy to describe the geometry of the drive to the controller so it could do the LLF. Newer disks use many complex internal structures, including zoned bit recording to put more sectors on the outer tracks than the inner ones, and embedded servo data to control the head actuator. They also transparently map out bad sectors. Due to this complexity, all modern hard disks are low-level formatted at the factory for the life of the drive.
*****There's no way for the PC to do an LLF on a modern IDE/ATA or SCSI hard disk*****
, and there's no reason to try to do so.
Older drives needed to be re-low-level-formatted occasionally because of the thermal expansion problems associated with using stepper motor actuators. Over time, the tracks on the platters would move relative to where the heads expected them to be, and errors would result. These could be corrected by doing a low-level format, rewriting the tracks in the new positions that the stepper motor moved the heads to. This is totally unnecessary with modern voice-coil-actuated hard disks.

Hard drive manufacturers have created for modern drives replacements for the old LLF utilities. They cause some confusion, because they are often still called "low-level format" utilities. The name is incorrect because, again, no utility that a user can run on a PC can LLF a modern drive. A more proper name for this sort of program is a zero-fill and diagnostic utility. This software does work on the drive at a low level, usually including the following functions (and perhaps others)

. It means that if another person try to download the service pack1 with a copy of WinXP with the same serial number it won’t let it happen cause it was used already and it’s on the MS database. In the other hand, it will let you download all the other updates. The best choice is to get a serial number of a corporate version of WinXP. Another way could be to order a CDROM with service pack1.
Good or Bad have no meaning at all, depends on what your point of view is.
