Formatting??

When vista starts loading it will show you the drive it found and at the bottom of the screen it has an option to format the drive.

Actually, it will Partition the drive first. That means deciding how to divide up the available space into one or more logical drives. I recommend making one drive that takes up all the HDD space available, but others have different ideas. You have to make a choice and tell it how you want that done. Then you let it know which logical drive will be the Boot Drive - if you chose to make only one drive, the answer is obvious and it may never even ask you.

It also may ask you which File System to use - FAT32 or NTFS. If you have a choice, definitely go with NTFS. It is much better and handles large HDD's properly. The only downside is that you cannot read/write an NTFS disk on an older DOS machine, which you probably will never need to do.

Once it does that, it will do the Format for you, also. IF it gives you a chance, you can choose between a Quick format which defines all the places to put data and creates the root directory and related data-tracking structures, or a Full format which will do those jobs and then test out every section of the disk surface. A Full Format will take MANY hours with a large HDD, but if you want the security of knowing the entire disk has been tested and proven, you can let it do that.

When all that prep work is done, vista will proceed with the actual installation to the new disk.

im ahving trouble getting my HDD back xD.
