On the Windows Advanced Options menu, use the arrow keys to select Safe Mode
and press the Enter key.

Log on to Windows Vista. When the Desktop message appears, click Yes to continue
in Safe Mode.

After Windows Vista starts, use the procedure described above to run the Disk
Defragmenter program.

Hewlett-Packard and Compaq computers with the Windows Vista operating system
preinstalled may appear to have a hard disk drive smaller than what is 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.
Windows Vista 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 Windows Vista and the size advertised. The
storage capacity of the hard disk drive is as advertised.
Windows Vista 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.
