About Hard Disk Drive 
Your Notebook is equipped with a 2.5-inch IDE (Integrated Drive Electronics) 
hard disk drive. The hard disk drive is a storage device with much higher speed 
and larger capacity than other storage devices, such as the floppy disk drive and 
optical storage devices.  Therefore, it is usually used to install the operating 
system and software applications.
