Understanding hard disk drive space

The hard disk drive on the Hewlett-Packard and

Compaq computers with the Microsoft®

Windows® operating system preinstalled may

appear to be smaller than the size stated in the

product specifications, in the documentation, or

on the box. Hard disk drives are described and

advertised by manufacturers in terms of decimal

(base 10) capacity. Microsoft Windows and

other programs, such as FDISK, use the binary

(base 2) numbering system.

In decimal notation, one megabyte (MB) is

equal to 1,000,000 bytes, and one gigabyte

(GB) is equal to 1,000,000,000 bytes. In the

binary numbering system, one megabyte is

equal to 1,048,576 bytes, and one gigabyte is

equal to 1,073,741,824 bytes. Because of the

different measuring systems, you may see a

difference between the size reported by

Microsoft Windows and the size advertised. The

storage capacity of the hard disk drive is as

advertised.

Microsoft Windows reports smaller capacity in

the Windows Explorer tool and in the computer

window because it shows information about one

partition on the hard disk drive at a time. One of

the partitions contains the System Recovery

information.

Note about systems configured with 4 GB of

memory

For computers with a 32 bit operating system,

all memory above 3 GB may not be available

because of system resource requirements.

This limitation is not limited to HP and Compaq

systems. The memory above 3 GB is used for

system resources.

Confirming total memory

The system BIOS displays the full 4 GB of

installed memory.

1. Turn on the PC.

2. Press F10. The BIOS menu is displayed.

Confirm the Total Installed Memory.
