I do not think its slim size to maintain on the size to define the system, and all of the activity to find the all things to depend the bad sector and formatting system to use them the way to find the activity.purchasing the things its matter to define the things of Slim.
I am chooses the this product from the other product.and its not choice only for bad sector problem .and the things to be chosen. Formatting the more things its not depending the all things.
I only like the WD hard disk to find the all of the activity to using them.and product to using of them.WD harddisk is the world like to chooses as comparison to this hard disk.
