Why does My Computer Show a Smaller Hard Disk Size than the Advertised
Size, e.g. 112GB Instead of the Advertised 120GB?
Solution: The reason is the different units used for calculating this value. All
manufacturer documents use units referring to base 10 digits. Therefore, 120 GB
correspond to 120 billion bytes (this is a 120 followed by 9 zeros). However, the
computer calculates using units based on 1024. 1 GB is equal to 1024 * 1024 *
1024 bytes = 1 073 741 824 bytes. Thus, for the computer 1 GB is a little more
than 1 billion bytes. The conversion of the (decimal) 120 GB is: (120 billion)
divided by (1 073 741 824) = approx. 112 GB in units of 1024 for the computer.
How can I determine the exact capacity of the hard disk?
Solution: Open the Control Panel, followed by the Administrative Tools folder. All
system programs of this folder are displayed. Open Computer Management .
Computer Management is a general program that includes an area with the name
Storage. Click on the + symbol in front of this area and select the suboption Disk
Management . On the right of the window, all the existing data media are
displayed. Disk 0 represents the system hard disk. The list also displays the total
size and the partitions on each medium, along with the size of each partition.
Please note: currently there is more than one partition because of the Recovery
and Driver partitions. These partitions total the following size of the hard disk.
